BackgroundHeart failure (HF) with chronic arrhythmias is associated with autonomic dysfunction and poor outcomes. Heart rate variability (HRV) reflects autonomic dysfunction and predicts outcomes in HF. This study invest...

OBJECTIVES: Sudden cardiac death (SCD) is common in patients with end-stage renal disease receiving hemodialysis. SCD may be caused by electrolyte imbalance or malignant arrhythmias in hemodialysis patients. We aimed to ...

Abstract Multifocal Ectopic Purkinje-related Premature Contractions (MEPPC) syndrome is a recently recognized rare channelopathy caused by gain-of-function mutations in the SCN5A gene, leading to a high burden of prematu...

ABSTRACT Background Daily variability of heart rate in 24‐h Holter recordings in dogs with atrial fibrillation (AF) receiving antiarrhythmic drugs (AAD) is unknown and could influence medical decisions. Hypothesis/Obje...

Abstract Background Reliable ECGs are crucial for diagnosing arrhythmias, yet a lack of standardization impedes arrhythmia diagnosis and treatment in horses. Objectives To objectively determine an optimal position of Ein...

Drug-induced cardiac arrhythmias are central to physiology and pharmacology education, yet students often struggle to connect electrophysiological mechanisms with dynamic electrocardiographic (ECG) changes. We developed ...

Abstract Background Myocardial sleeves of the caudal vena cava are the predilection site for atrial tachycardia (AT) in horses. Caudal vena cava isolation guided by the ablation index, a lesion quality marker incorporati...

Abstract BackgroundAtrial fibrillation (AF) and atrial flutter (AFL) are common arrhythmias associated with the risk of ischemic stroke, which can be reduced with anticoagulation therapy. Thus, early diagnosi...

Abstract Background The protozoal parasite Trypanosoma cruzi causes myocarditis in dogs. Objectives To describe the cardiac diagnostic test results and outcomes of dogs naturally infected with T. cruzi. Animals Forty‐f...

Carbamazapine is a commonly used antiepileptic agent. Neurological abnormalities which can progress to coma, arrhythmias, respiratory depression and eye abnormalities such as nystagmus are seen in an intoxication setting...
