Syncope and hypotension associated with carotid sinus hypersensitivity in a patient with nasopharyngeal carcinoma: A case report.

Medicine (Baltimore) 2018 Sep;97(37):e12335

Department of Cardiology.

Rationale: Carotid sinus hypersensitivity (CSH) is traditionally classified into 3 subgroups: cardioinhibitory, vasodepressor, and mixed subtypes. However, the underlying mechanism of CSH in head and neck cancer is controversial. Several pathological mechanisms of CSH have been proposed: atherosclerotic noncompliance, sternocleidomastoid proprioceptive denervation, and generalized autonomic dysfunction. Read More

Adenosine hypersensitivity and atrioventricular block.

Herzschrittmacherther Elektrophysiol 2018 Jun 29;29(2):166-170. Epub 2018 May 29.

Service de Cardiologie, CHU La Timone, 13005, Marseille, France.

Adenosine is a ubiquitous substance that is released under several physiological and pathological conditions and has cardiovascular effects including cardioinhibition and vasodilation. It has been shown to be an important modulator implicated in several forms of syncope. In patients with chronic low plasma levels of adenosine, a transient release of endogenous adenosine can be sufficient to block conduction in the atrioventricular node and induce prolonged asystole; conversely, when plasma adenosine levels are chronically high, adenosine release is responsible for vasodepression.

Purines and Carotid Body: New Roles in Pathological Conditions.

Front Pharmacol 2017 12;8:913. Epub 2017 Dec 12.

Centro de Estudos de Doenças Crónicas, NOVA Medical School - Faculdade de Ciências Médicas, Universidade NOVA de Lisboa, Lisboa, Portugal.

It is known that adenosine and adenosine-5'-triphosphate (ATP) are excitatory mediators involved in carotid body (CB) hypoxic signaling. The CBs are peripheral chemoreceptors classically defined by O, CO, and pH sensors. When hypoxia activates the CB, it induces the release of neurotransmitters from chemoreceptor cells leading to an increase in the action potentials frequency at the carotid sinus nerve (CSN).

Carotid sinus hypersensitivity: block of the sternocleidomastoid muscle does not affect responses to carotid sinus massage in healthy young adults.

Physiol Rep 2017 Oct 16;5(19). Epub 2017 Oct 16.

Department of Biomedical Physiology and Kinesiology, Simon Fraser University, Burnaby, British Columbia, Canada

The arterial baroreflex is crucial for short-term blood pressure control - abnormal baroreflex function predisposes to syncope and falling. Hypersensitive responses to carotid baroreflex stimulation using carotid sinus massage (CSM) are common in older adults and may be associated with syncope. The pathophysiology of this hypersensitivity is unknown, but chronic denervation of the sternocleidomastoid muscles is common in elderly patients with carotid sinus hypersensitivity (CSH), and is proposed to interfere with normal integration of afferent firing from the carotid baroreceptors with proprioceptive feedback from the sternocleidomastoids, producing large responses to CSM.

[Carotid sinus massage is not a benign intervention].

Ned Tijdschr Geneeskd 2017 ;161:D1312

AMC, afd. Cardiologie, Amsterdam.

Carotid sinus massage for diagnosis and termination of supraventricular tachycardia (SVT) is still a widely used vagal manoeuvre in the A&E department. However, itsefficacy is limited (termination of the SVT in approximately 20%) and carotid sinus massage may be complicated by (potentially devastating) neurologic complications in 0.2-1% of the patients.

Swallow-induced syncope and carotid sinus hypersensitivity: Coincident or associated conditions?

J Electrocardiol 2017 Jul - Aug;50(4):523-525. Epub 2017 Mar 14.

Department of Cardiology, Soroka University Medical Center and Faculty of Health Sciences, Ben-Gurion University of the Negev, Beer-Sheva, Israel.

Swallow induced syncope is a rare clinical condition which is thought to result from an abnormal vagal reflex leading to bradycardia and cerebral hypoperfusion. It mostly occurs in patients with organic or functional disorders of the esophagus, and often requires permanent pacemaker implantation, along with treatment of the underlying esophageal pathology. In the following case, we report of a 71-year-old male with achalasia post per oral endoscopic myectomy, who presented with syncope and documented AV-block while eating solid food. Read More

A case of asystole from carotid sinus hypersensitivity during patient positioning for thyroidectomy.

BMC Anesthesiol 2016 10 6;16(1):85. Epub 2016 Oct 6.

Department of General Surgery, University Hospital of Crete, Heraklion, Crete, Greece.

Background: We present a case of a patient with multinodular goiter disease who suffered asystole during head hyperextension for surgical positioning on the operational table.

Case Presentation: Manipulation of carotid sinus may trigger bradycardia or even asystole even in patients without prior history of carotid sinus hypersensitivity. The time proximity between patient positioning and asystole, the late responsiveness to atropine, the immediate increase of heart rate after head elevation and the lack of any other trigger factor or prior history support the hypothesis of carotid sinus syndrome.

Neurocardiovascular Instability and Cognition.

Yale J Biol Med 2016 03 24;89(1):59-71. Epub 2016 Mar 24.

Professor of Medical Gerontology, Mercer's Institute for Successful Ageing, St. James' Hospital, Hospital 4 Top Floor, Dublin 8, Ireland.

Neurocardiovascular instability (NCVI) refers to abnormal neural control of the cardiovascular system affecting blood pressure and heart rate behavior. Autonomic dysfunction and impaired cerebral autoregulation in aging contribute to this phenomenon characterized by hypotension and bradyarrhythmia. Ultimately, this increases the risk of falls and syncope in older people. Read More

Chronic Interactions Between Carotid Baroreceptors and Chemoreceptors in Obesity Hypertension.

Hypertension 2016 07 9;68(1):227-35. Epub 2016 May 9.

From the Department of Physiology and Biophysics, University of Mississippi Medical Center, Jackson (T.E.L.); Department of Pharmacology (R.I.) and Department of Physiology (I.T.), University of Medicine and Pharmacy, "Gr. T. Popa," Iasi, Romania; Colonial Pipeline Company, Atlanta, GA (R.C.); CVRx, Inc., Minneapolis, MN (A.W.C., D.G.); and North Memorial Medical Center, Trauma Services, Robbinsdale, MN (E.D.I.).

Carotid bodies play a critical role in protecting against hypoxemia, and their activation increases sympathetic activity, arterial pressure, and ventilation, responses opposed by acute stimulation of the baroreflex. Although chemoreceptor hypersensitivity is associated with sympathetically mediated hypertension, the mechanisms involved and their significance in the pathogenesis of hypertension remain unclear. We investigated the chronic interactions of these reflexes in dogs with sympathetically mediated, obesity-induced hypertension based on the hypothesis that hypoxemia and tonic activation of carotid chemoreceptors may be associated with obesity.

Tilt table test today - state of the art.

World J Cardiol 2016 Mar;8(3):277-82

Nicholay Teodorovich, Moshe Swissa, Kaplan Medical Center, the Hebrew University, Jerusalem 91120, Israel.

A tilt table test (TTT) is an inexpensive, noninvasive tool for the differential diagnosis of syncope and orthostatic intolerance and has good diagnostic yield. The autonomic system malfunction which underlines the reflex syncope is manifested as either hypotension or bradycardia, while an orthostatic challenge is applied. The timing of the response to the orthostatic challenge, as well as the predominant component of the response help to differentiate between various forms of neurocardiogenic syncope, orthostatic hypotension and non-cardiovascular conditions (e.

Dipartimento di Medicina Clinica e Molecolare - Azienda Ospedaliera Sant' Andrea, University of Rome, Italy.

Nowadays, syncope still generates complicated challenges for clinicians for the alarm it arises in patients and, at the same time, for the multiple causes it has determined by. In almost one third of cases, syncope is neuromediated, in young subjects in vasovagal, whereas in elderly is often determinated by carotid sinus hypersensitivity. These two kinds of syncope have two completely different diagnostic approach. Read More

Symptomatic presentation of carotid sinus hypersensitivity is associated with impaired cerebral autoregulation.

Institute for Ageing and Health, Newcastle University and Falls and Syncope Service, Royal Victoria Infirmary, Newcastle upon Tyne, United Kingdom (S.J.K., S.W.P.).

Background: Carotid sinus hypersensitivity (CSH) is associated with syncope, unexplained falls, and drop attacks in older people but occurs asymptomatically in 35% of community-dwelling elders. We hypothesized that impaired cerebral autoregulation is associated with the conversion of asymptomatic CSH to symptomatic CSH. We therefore conducted a case-control study evaluating individuals with CSH with and without the symptoms of syncope or unexplained falls, as well as non-CSH controls, to determine whether the blood pressure and heart rate changes associated with CSH are associated with symptoms only when cerebral autoregulation is altered.

Implications of carotid sinus hypersensitivity following preoperative embolization of a carotid body tumor. An indication for prophylactic intraoperative cardiac pacing.

JAMA Otolaryngol Head Neck Surg 2014 May;140(5):459-63

IMPORTANCE Carotid body tumors are rare neoplasms of neural crest origin that are both highly vascularized and locally invasive. Treatment options for these tumors often include surgery with preoperative embolization, which can pose major cardiovascular risk to patients. As demonstrated by this case report, hemodynamic instability following preoperative embolization of a carotid body tumor may indicate severe carotid sinus hypersensitivity and the need for temporary cardiac pacing.

Aerobic training in older adults with type 2 diabetes and vasodepressive carotid sinus hypersensitivity.

Aging Clin Exp Res 2013 Dec 22;25(6):651-7. Epub 2013 Oct 22.

VITALiTY (Vancouver Initiative to Add Life to Years) Research Laboratory, Division of Geriatric Medicine, Department of Medicine, University of British Columbia, Vancouver, BC, Canada,

Background And Aims: Vasodepressive carotid sinus hypersensitivity (V-CSH) is a common but incurable etiology for fainting in older adults with diabetes (OADM), and is diagnosed by carotid sinus massage (CSM). Aerobic exercise has been shown to be an effective therapy for other neuroautonomic etiologies of syncope (such as orthostatic hypotension), but the effectiveness of aerobic training in V-CSH remains unknown. We examined whether aerobic training could attenuate the vasodepressive response to CSM in OADM (older adults with type 2 diabetes) subjects complicated by V-CSH. Read More

Head turning-induced hypotension in elderly people.

PLoS One 2013 16;8(8):e72837. Epub 2013 Aug 16.

Department of Geriatric Medicine Radboud University Nijmegen Medical Centre, Nijmegen, The Netherlands.

Carotid sinus hypersensitivity has a high prevalence in the elderly and is a possible cause of falls. In carotid sinus hypersensitivity, external triggers cause sudden reductions in blood pressure, leading to dizziness or syncope, resulting in falls. Turning of the head is considered an important example of such an external trigger in everyday life, wherein rotation of the neck is thought to manipulate the hypersensitive carotid sinus. Read More

Neurocardiogenic syncope and associated conditions: insight into autonomic nervous system dysfunction.

Turk Kardiyol Dern Ars 2013 Jan;41(1):75-83

Department of Syncope and Electrophysiology, ND Secours/USEK University Hospital, Byblos, Lebanon.

Neurocardiogenic syncope is known to be associated with autonomic nervous system dysfunction, although the mechanism has not been entirely elucidated. In this study, we sought to highlight the pathogenic role of the autonomic nervous system in neurocardiogenic syncope and to review the associated co-morbidities known to have a dysautonomic basis. Herein we discuss migraine, orthostatic hypotension, postural orthostatic tachycardia syndrome, endothelial dysfunction, chronic fatigue syndrome, and carotid sinus hypersensitivity with a focus on the pathogenic role of the autonomic nervous system and any consecutive clinical implications.

At the heart of the arterial baroreflex: a physiological basis for a new classification of carotid sinus hypersensitivity.

J Intern Med 2013 Apr;273(4):345-58

Department of Internal Medicine, Academic Medical Centre, University of Amsterdam, Amsterdam, the Netherlands.

The aim of this review is to provide an update of the current knowledge of the physiological mechanisms underlying reflex syncope. Carotid sinus syncope will be used as the classical example of an autonomic reflex with relatively well-established afferent, central and efferent pathways. These pathways, as well as the pathophysiology of carotid sinus hypersensitivity (CSH) and the haemodynamic effects of cardiac standstill and vasodilatation will be discussed. Read More

Prevention of falls in the elderly--a review.

Osteoporos Int 2013 Mar 8;24(3):747-62. Epub 2013 Jan 8.

Clinical and Molecular Osteoporosis Research Unit, Department of Orthopedics and Clinical Sciences, Skåne University Hospital, Lund University, 205-02 Malmö, Sweden.

The proportion of elderly in the society increases and fall frequency increases with advancing age. Many falls result in fractures and also soft tissue injuries, longstanding pain, functional impairment, reduced quality of life, increased mortality, and excess in healthcare costs. Due to the magnitude of these negative effects, a variety of single- and multicomponent fall-preventive intervention programs has been initiated. Read More

Carotid sinus hypersensitivity was first reported more than 200 years ago. Nevertheless, a complete understanding of this relatively common clinical finding in older patients has proven elusive. There is evidence to support an association between symptoms, particularly syncope, and a hypersensitive response to carotid sinus massage. Read More

Geriatric hypotensive syndromes are not explained by cardiovascular autonomic dysfunction alone.

J Gerontol A Biol Sci Med Sci 2013 May 15;68(5):581-9. Epub 2012 Oct 15.

Department of Geriatric Medicine, Radboud University Nijmegen Medical Centre, The Netherlands.

Background: Though highly prevalent, the pathophysiology of orthostatic hypotension (OH), postprandial hypotension (PPH), and carotid sinus hypersensitivity (CSH) are rarely studied together. Therefore, we conducted such a comprehensive study focusing on the common role of the cardiovascular autonomic system. We hypothesized that in geriatric patients, OH, PPH, and CSH are manifestations of cardiovascular autonomic dysfunction and investigated state-of-the-art cardiovascular autonomic function indices in a group of geriatric falls or syncope patients.

Recurrent syncope in patients with carotid sinus hypersensitivity.

ISRN Cardiol 2012 10;2012:216206. Epub 2012 Sep 10.

UO Emergency Medicine and Syncope Unit, Ospedale Santa Maria Nuova-Firenze, Piazza S. Maria Nuova, 1-50131, Florence, Italy ; Cardiology Unit, Electrophysiology and Syncope Unit, Ospedale Santa Maria Nuova-Firenze, Piazza S. Maria Nuova, 1-50131, Florence, Italy.

Syncope recurrence in pacemaker-implanted subjects for the cardio-inhibitory response to sinus carotid massage (SCM) was investigated. The study-hypothesis was that recurrences had significant vasodepressor responses that could justify the loss of consciousness. Forty-six patients were enrolled (16 patients and 30 controls), followed and revaluated after 5-7 years. Read More
