Evaluation of analgesic interaction between morphine, maropitant and dexmedetomidine in dogs undergoing ovariohysterectomy.

N Z Vet J 2021 May 5:1-27. Epub 2021 May 5.

School of Veterinary Science, Massey University, Palmerston North, New Zealand.

Aims: To compare the analgesic effect of morphine combined with maropitant and/or dexmedetomidine to morphine alone given at a higher dose, and to evaluate the pharmacokinetics of the drug combinations, in dogs undergoing ovariohysterectomy (OHE).

Methods: Forty client owned-dogs were randomised into four treatment groups (n=10 per group) each to receive a different analgesic protocol. After premedication with I/M acepromazine anaesthesia was induced with propofol to effect and maintained with isoflurane in 100% oxygen delivered via a circle system. Read More

Remote Heart Rhythm Monitoring by Photoplethysmography-Based Smartphone Technology After Cardiac Surgery: Prospective Observational Study.

JMIR Mhealth Uhealth 2021 Apr 15;9(4):e26519. Epub 2021 Apr 15.

Department of Cardiac Surgery, University Hospitals Leuven, Leuven, Belgium.

Background: Atrial fibrillation (AF) is the most common arrhythmia after cardiac surgery, yet the precise incidence and significance of arrhythmias after discharge home need to be better defined. Photoplethysmography (PPG)-based smartphone apps are promising tools to enable early detection and follow-up of arrhythmias.

Objective: By using a PPG-based smartphone app, we aimed to gain more insight into the prevalence of AF and other rhythm-related complications upon discharge home after cardiac surgery and evaluate the implementation of this app into routine clinical care. Read More

Second-degree atrioventricular block after administration of methylergometrine for treatment of uterine atony during cesarean section.

Rev Esp Anestesiol Reanim 2021 Apr 7. Epub 2021 Apr 7.

Servicio de Anestesiología y Reanimación, Complejo Hospitalario Universitario de Canarias, San Cristóbal de La Laguna, Santa Cruz de Tenerife, España.

Mortality due to cardiovascular disease in pregnancy is a growing problem in developed countries, being nowadays the leading cause of maternal death. Within this group, the most common cause of death are congenital or acquired heart diseases, representing a challenge in the management of these patients, since the pregnancy-related physiological alterations can impair their basal condition and treatment. We present the case of a 34-year-old patient, without any relevant pathological antecedents, who developed a second-degree atrioventricular block, Mobitz type I, following the administration of methylergometrine during cesarean section due to failure to progress in labour.

Clinical symptoms of limited exercise capacity linked to AAI-DDD functionality: An in silico and in vivo approach.

Pacing Clin Electrophysiol 2021 May 21;44(5):943-951. Epub 2021 Apr 21.

Cardiovascular Research Center, Onze-Lieve-Vrouw Hospital Aalst, Moorselbaan 164, Aalst, B-9300, Belgium.

Background: Exercise capacity is an important aspect of quality of life in patients undergoing pacemaker implantation. Device algorithms for ventricular pacing avoidance have been developed to avoid unnecessary and potentially harmful effects of right ventricular pacing. However, little data exists on the immediate response of these algorithms to sudden AV block during exercise. Read More

A Validated Smartphone-based Electrocardiogram Reveals Severe Bradyarrhythmias during Immobilizing Restraint in Mice of Both Sexes and Four Strains.

J Am Assoc Lab Anim Sci 2021 Mar 26;60(2):201-212. Epub 2021 Feb 26.

Center for Animal Resources and Education, Cornell University, College of Veterinary Medicine, Ithaca, New York.

Mouse handling and restraint affect behavior, physiology, and animal welfare, yet little information is available on how various mouse restraint methods affect cardiovascular parameters. We validated the use of a smartphone-based ECG sys- tem in mice by performing simultaneous smartphone and telemetry ECG recordings in conscious, restrained mice and in anesthetized mice. We observed that mice held in standard immobilizing restraint ("scruffing") experienced severe bradycardia. Read More

Complete atrioventricular block and permanent pacemaker implantation following percutaneous coronary intervention to left anterior descending artery chronic total occlusion.

Cardiovasc Revasc Med 2021 Jan 23. Epub 2021 Jan 23.

Cardiology Department, AHEPA General Hospital, Aristotle University of Thessaloniki, Greece.

A 72-year-old male patient, with first degree atrioventricular block and LBBB on his baseline ECG, developed persistent complete atrioventricular block after recanalization of a chronic total occlusion of his left anterior descending artery (LAD) and ultimately underwent permanent pacemaker implantation. Occlusion of the second septal branch, probably supplying the right branch of the His bundle is speculated to have led to this complication. During elective intervention to the LAD territory in patients with prior conduction abnormalities on the ECG, care should be taken to preserve normal blood flow to the septal perforators. Read More

High-risk atrioventricular block in Brugada syndrome patients with a history of syncope.

J Cardiovasc Electrophysiol 2021 Mar 19;32(3):772-781. Epub 2021 Jan 19.

Department of Cardiovascular Medicine, Division of Arrhythmia and Electrophysiology, National Cerebral and Cardiovascular Center, Osaka, Japan.

Background: Determining the etiology of syncope is challenging in Brugada syndrome (BrS) patients. Implantable cardioverter defibrillator placement is recommended in BrS patients who are presumed to have arrhythmic syncope. However, arrhythmic syncope in BrS patients can occur in the setting of atrioventricular block (AVB), which should be managed by cardiac pacing. Read More

Curr Med Sci 2020 Dec 11;40(6):1191-1202. Epub 2021 Jan 11.

Department of Cardiology, Remin Hospital, Wuhan University, Wuhan, 430060, China.

Lorenz-RR scatter plot has an obvious shortcoming in that it does not indicate the time when the scatter point happens. On the Lorenz RR scatter plot, one cannot know the time during which the cardiac rhythms take place. Since occurrence of cardiac rhythms is time-related, time should be introduced to such plots.

Immune-Mediated Fetal Complete Atrioventricular Block: Can Dexamethasone Therapy Revert the Process?

Isr Med Assoc J 2020 Nov;11(22):711-716

Department of Pediatric Cardiology, Hadassah Hebrew University Hospital, Jerusalem, Israel.

Background: Fetal complete atrioventricular block (CAVB) is usually autoimmune mediated. The risk of developing CAVB is 2% to 3% in anti-Ro/SS-A seropositive pregnancies and it increases 10 times after previous CAVB in siblings. Despite being a rare complication, CAVB carries a 20% mortality rate and substantial morbidity, as about 65% of newborns will eventually need life-long pacing. Read More

Interferons and innate immune activation in autoimmune congenital heart block.

Scand J Immunol 2021 Jan;93(1):e12995

Division of Rheumatology, Department of Medicine, Karolinska Institutet, Karolinska University Hospital, Stockholm, Sweden.

Autoimmune congenital heart block (CHB) may develop in foetuses of women carrying anti-Ro/SSA and La/SSB autoantibodies and is characterized by disruption of signal conduction at the atrioventricular (AV) node, resulting in partial or complete AV block. If not fatal in utero, complete CHB typically requires lifelong cardiac pacing. No treatment has so far been unequivocally demonstrated to prevent or treat autoimmune CHB, and the relatively low incidence (1%-5%) and recurrence (12%-16%) rates of second/third-degree AV block add to the complexity of managing pregnancies in women with anti-Ro/La antibodies.

Pectus excavatum requiring temporary pacemaker implantation before Nuss procedure: a case report.

J Thorac Dis 2020 Sep;12(9):4985-4990

Department of Thoracic Surgery, Cancer Hospital of China Medical University, Liaoning Cancer Hospital & Institute, Shenyang, China.

Pectus excavatum is the most common chest wall deformity, and some patients also have it combined with cardiac arrhythmias. It is a rare occurrence for there to be a severe conduction block that requires a temporary pacemaker implantation before the surgical correction. Here we reported a case of pectus excavatum with a second-degree atrial-ventricular (AV) block (Mobitz II) who had temporary pacemaker implantation before the Nuss procedure. Read More
