INTRODUCTION: Atrial premature complexes have been reported to be the most common arrhythmia in cattle and is suspected to be secondary to systemic disease, especially gastrointestinal disease. In order to properly identify pathologic arrhythmia in cattle, the normal rhythm and arrhythmia prevalence should be defined. The objective of this study was to determine the normal heart rate, rhythm, number of ventricular premature complexes (VPCs), and atrial premature complexes (APCs) in unrestrained Angus steers...

Bayés syndrome is an under-recognized clinical condition characterized by inter-atrial block (IAB). This is defined electrocardiographically as P-wave duration > 120 ms and can be categorized into first, second and third degree IAB. It can be caused by inflammatory conditions such as systemic sclerosis and rheumatoid arthritis, abnormal protein deposition in cardiac amyloidosis, or neoplastic processes invading the inter-atrial conduction system, such as primary cardiac lymphoma. It may arise transiently during volume overload, autonomic dysfunction or electrolyte disturbances from vomiting...

A female ferret was referred as an emergency for severe respiratory distress symptoms. At presentation, the patient was listlessness, dyspnoeic, and hyper-responsive. The clinical examination evidenced dyspnea with cyanosis, altered cardiac rhythm, and hepatomegaly. Electrocardiography showed an advanced second-degree atrioventricular (AV) block. The liver aspirate was diagnostic for lymphoma. The patient did not respond to supportive therapy and rapidly died. Post-mortem exams confirmed the presence of lymphoma with hepatic involvement...

Mutations in the lamin A/C gene (LMNA) have been associated with several phenotypes ranging from systemic to prevalent of muscle, heart, skin, nerve etc. More recently they have been associated with dilated cardiomyopathy (DCM) and severe forms of arrhythmogenic right ventricular cardiomyopathy (ARVC). We report four novel mutations - 3 missense and 1 deletion - in 4 unrelated patients showing different phenotypes, ranging from the early onset congenital form of laminopathy to classical LGMD phenotype, to LGMD and heart involvement...

PURPOSE: Intraoperative neuromonitoring of recurrent laryngeal nerve function after stimulation of the vagus nerve has been embraced as a risk minimization tool in thyroid surgery to prevent recurrent laryngeal nerve injury. Because this technology is increasingly used in an elderly and sicker population, the present study was conducted to determine the safety of this method in patients with second- or third-degree atrioventricular block. METHODS: This study aimed at evaluating the feasibility and safety of continuous intraoperative neuromonitoring (CIONM) in patients with second- or third-degree atrioventricular block...

BACKGROUND: We evaluated the outcomes of patients undergoing surgical repair of partial atrioventricular septal defect (AVSD) and analyzed the effect of age on outcome. METHODS: In this single-center retrospective study, we included all children who underwent repair of partial AVSD between 1990 and 2014. We divided the patients into 4 age quartiles (first quartile: 0-0.75 years, n = 22; second quartile: 0.75-1.5 years, n = 21; third quartile: 1.5-3.75 years, n = 22; and fourth quartile: >3...

Acute excessive alcohol consumption is associated with heart rhythm disorders like atrial fibrillation but also premature ventricular contractions, collectively known as the "holiday heart syndrome". More rarely but clinically significant are reports of atrioventricular (AV) conduction disturbances in binge drinkers with no underlying heart disease or chronic alcohol consumption. To obtain better insights into common denominators and the potential underlying mechanisms we collected and compared individual case reports of AV block following acute alcohol intoxication in otherwise healthy people...

BACKGROUND: Patients initiated on Gilenya (fingolimod) require cardiovascular monitoring for 6h after the first dose. Novartis has engaged an independent provider (Regent's Park Heart Clinics [RPHC]) to provide a first dose observation (FDO) service to UK neurologists. OBJECTIVES: To describe routinely-documented clinical observations (heart rate [HR], blood pressure [BP], cardiac rhythm [CR]) and outcomes from the RPHC fingolimod FDO service. METHODS: Pseudonymised data (clinical observations pre-dose and for 6h after the first dose and any requirement for extended monitoring) were collected retrospectively from RPHC records for the first 850 RPHC FDO episodes (undertaken Jul-2012 to Jan-2015)...

AIMS: Although syncope is the main reason for cardiac pacing in ∼40% of patients affected by atrioventricular block (AVB), very few data are available on the benefit of cardiac pacing in preventing syncopal recurrences. METHODS AND RESULTS: We retrospectively evaluated 229 consecutive patients (124 males, age 80 ± 10 years) who had received a permanent pacemaker from January 2009 to December 2013 for AVB and syncope (94 patients, 41%) or AVB without syncope (135 patients, 59%)...

Cardiac arrhythmias are commonly reported in freedivers during maximal voluntary breath-holds, but their influence on the cardiological status and their long-term effects on the cardiac health of these athletes have not been investigated. Here we present the results of a study on 32 healthy young men (mean age 32.6 ± 1.3 years) who were divided into two groups of 16 subjects. One group included 16 continuously training freedivers at the "high achievers in sports" level (DIVERS group). The CONTROL group included 16 healthy young men not involved in sports...

In the first part a prospective cohort study was reported to evaluate the efficacy and safety of a treatment protocol including plasma exchange (PE) or PE plus intravenous immunoglobulins (IVIG) or immunoadsorption (IA) plus IVIG administered in addition to conventional therapy to 22 pregnant women with high-risk APS. The results indicate that PE or IA treatments administered along with IVIG and conventional antithrombotic therapy could be a valuable and safe therapeutic option in pregnant APS women with triple antiphospholipid antibody positivity along with a history of thrombosis and/or one or more severe pregnancy complications...

Regulatory agencies encourage sponsors to submit 24-hour ambulatory ECG data for assessing cardiac safety of new drugs, and some arrhythmias, hitherto considered rare, have been observed in some early-phase studies. Interpretation of these observations is difficult given the dearth of published data on the prevalence of cardiac arrhythmias seen during 24-hour continuous ECG monitoring in healthy volunteers (HV) from clinical trials. We analyzed drug-free ambulatory ECG recordings from 1273 HV (1000 males, 273 females; age 18-65 years) from 22 phase 1 studies that were analyzed in a core ECG laboratory; all subjects had normal screening ECGs...

OBJECTIVE: To evaluate the cardiac and pulmonary effects of siponimod (BAF312) and propranolol co-administration in healthy subjects. METHODS: Healthy subjects (n=76) were randomized in a doubleblind manner to receive propranolol at siponimod steady state (group A), siponimod at propranolol steady state (group B), placebo (group C) and propranolol (group D). Pharmacodynamic evaluations included maximum change from baseline in time-matched hourly average heart rate (Emax HR) and mean arterial blood pressure (Emax MABP) over 24 hours postdose, change from baseline in PR intervals, cardiac rhythm, and forced expiratory volume in 1 second (FEV1)...

BACKGROUND: Cardiac neonatal lupus syndrome is due to anti-SSA or SSB antibodies and mainly includes congenital heart block (CHB) and dilated cardiomyopathy (DCM). Its optimal management is still debated. We report a large series of autoimmune high degree CHB. METHODS: Inclusion criteria in this retrospective study were fetuses or neonates with high-degree CHB associated with maternal anti-SSA/SSB antibodies. RESULTS: 214 CHB were included: 202 detected in utero at a median term of 23 weeks' gestation (WG) [range 16 to 39 WG] and 12 neonatal cases diagnosed at a median age of 0 days [range birth to 8 days]...
