J Electrocardiol 2020 Apr 28;60:175-176. Epub 2020 Apr 28.

202 Birkdale Lane, Jupiter, FL 33458, United States of America. Electronic address:

A 42-year old female with no significant past medical history, normal physical exam, and normal routine lab studies presents with "thumps" in her chest. A Holter monitor evaluation revealed normal sinus rhythm with two different PR intervals suggesting "dual AV nodal pathways" and occasional blocked P waves with junctional escape complexes. The behavior was most suggestive that no conduction through either pathway reached the His bundle, suggesting distal block must be beyond each pathway, but still within the AV node. Read More

Pathophysiology, Diagnosis, and Ablation of Atrioventricular Node-dependent Long-R-P Tachycardias.

J Innov Card Rhythm Manag 2020 Mar 15;11(3):4046-4053. Epub 2020 Mar 15.

Department of Medicine, Division of Cardiology, Thomas Jefferson University Hospital, Philadelphia, PA, USA.

Atrioventricular (AV) node-dependent long-R-P tachycardias are a unique group of supraventricular tachycardias that include atypical AV nodal reentrant tachycardia (AVNRT), atypical AVNRT with a concealed bystander nodofascicular (NF)/nodoventricular (NV) accessory pathway inserting into the slow pathway of the AV node, the permanent form of junctional reciprocating tachycardia, and orthodromic NF/NV reciprocating tachycardia. Here, we discuss the complex pathophysiology, diagnosis, and ablation of these intriguing arrhythmias. Read More

[CME ECC 65: The Athlete's ECG].

Praxis (Bern 1994) 2020 ;109(4):253-258

Universitätsspital Zürich, Klinik für Kardiologie.

CME ECC 65: The Athlete's ECG Regular, intensive training in athletes causes a modulation of the heart due to higher vagal tone and emerging hypertrophy. To assess these changes, which can be seen in an athlete's ECG as well, an international group of experts constituted contemporary standards for ECG interpretation in athletes, the "Seattle Criteria" which are discussed in this article: Athletes often have a physiologic sinus bradycardia with a heart rate between 30 and 60 bpm and a pronounced respiratory arrhythmia. A junctional rhythm with retrograde depolarisation of the atria frequently occurs as well, especially at rest. Read More

Unusual variants of pre-excitation: From anatomy to ablation: Part III-Clinical presentation, electrophysiologic characteristics, when and how to ablate nodoventricular, nodofascicular, fasciculoventricular pathways, along with considerations of permanent junctional reciprocating tachycardia.

J Cardiovasc Electrophysiol 2019 12 14;30(12):3097-3115. Epub 2019 Nov 14.

Post Graduation Department, Faculdade de Ciências Médicas, Belo Horizonte, Brazil.

The recognition of the presence, location, and properties of unusual accessory pathways for atrioventricular conduction is an exciting, but frequently a difficult, challenge for the clinical cardiac arrhythmologist. In this third part of our series of reviews, we discuss the different steps required to come to the correct diagnosis and management decision in patients with nodofascicular, nodoventricular, and fasciculo-ventricular pathways. We also discuss the concealed accessory atrioventricular pathways with the properties of decremental retrograde conduction that are associated with the so-called permanent form of junctional reciprocating tachycardia.

A rat model of complete atrioventricular block recapitulates clinical indices of bradycardia and provides a platform to test disease-modifying therapies.

Sci Rep 2019 05 6;9(1):6930. Epub 2019 May 6.

Department of Pediatrics, Emory University, Atlanta, GA, USA.

Complete atrioventricular block (CAVB) is a life-threatening arrhythmia. A small animal model of chronic CAVB that properly reflects clinical indices of bradycardia would accelerate the understanding of disease progression and pathophysiology, and the development of therapeutic strategies. We sought to develop a surgical model of CAVB in adult rats, which could recapitulate structural remodeling and arrhythmogenicity expected in chronic CAVB. Read More

Vasopressin antagonist-like effect of acetazolamide in a heart failure patient: a case report.

Authors:
Hajime Kataoka

Eur Heart J Case Rep 2018 Sep 2;2(3):yty076. Epub 2018 Jul 2.

Division of Internal Medicine, Nishida Hospital, Tsuruoka-Nishi-Machi 2-266, Saiki-City, Oita, Japan.

Background: Hyponatraemia is easily corrected by treatment with an oral vasopressin antagonist, but these medications are costly and their use at outpatient clinics is restricted by government-managed insurance in Japan. Acetazolamide could be an alternative diuretic to a vasopressin antagonist.

Case Summary: An 83-year-old dyspnoeic male patient was emergently admitted to the hospital due to decompensated heart failure (HF), hypotension, and hyperkalaemia-associated sinus arrest with a junctional escape rhythm. Read More

Transient sinus arrest due to sinus node artery thrombus after revascularisation of the left circumflex artery.

BMJ Case Rep 2019 Feb 22;12(2). Epub 2019 Feb 22.

Cardiology, Albany Medical Center Hospital, Albany, New York, USA.

We present a case of sinus arrest and junctional escape rhythm from sinus node artery (SNA) thrombus in a 55-year-old man after revascularisation of right coronary and proximal circumflex arteries for infero-posterior wall ST-segement elevation myocardial infarction (STEMI). Sinus arrest from occlusion of the SNA is uncommon. The ensuing bradycardia may have haemodynamic consequences requiring temporary pacing but is almost always self-limited. Read More

Spinal Shox2 interneuron interconnectivity related to function and development.

Elife 2018 12 31;7. Epub 2018 Dec 31.

Department of Neurobiology and Anatomy, Drexel University College of Medicine, Philadelphia, United States.

Neuronal networks generating hindlimb locomotion are located in the spinal cord. The mechanisms underlying spinal rhythmogenesis are unknown but network activity and interconnectivity of excitatory interneurons likely play prominent roles. Here, we investigate interconnectivity within the Shox2 interneuron population, a subset of which has been suggested to be involved in locomotor rhythm generation, using paired recordings in isolated spinal cords or slices from transgenic mice.

Transient systolic anterior motion with junctional rhythm after mitral valve repair in the intensive care unit.

Crit Ultrasound J 2018 Nov 12;10(1):30. Epub 2018 Nov 12.

Department of Intensive Care Medicine, Tokyo Women's Medical University, 8-1, Kawada-cho, Shinjuku-ku, Tokyo, Japan.

Systolic anterior motion (SAM) after mitral valve repair (MVR) can adversely affect hemodynamics due to exacerbation of left ventricular outflow tract obstruction and mitral regurgitation. Intraoperative transient SAM after MVR can usually be managed with hemodynamic maneuvers under continuous monitoring by transesophageal echocardiography (TEE). However, during postoperative intensive care management, transient SAM is seldom diagnosed and the start of treatment may be delayed. Read More
