Arrhythmogenic right ventricular cardiomyopathy associated with severe left ventricular involvement in a cat. [PDF]

, 2009
An 8-year-old, 4 kg, intact female, domestic shorthaired cat was referred for tachypnea and pleural effusion. A 24-h Holter recording showed numerous polymorphic ventricular premature complexes with left and right bundle branch block morphology ...

Trade-off between elimination of premature ventricular complexes and loss of synchronized left ventricular pacing improved cardiac function in a patient with heart failure

Indian Pacing and Electrophysiology Journal, 2016
Synchronized left ventricular pacing (sLVP) via adaptive cardiac resynchronization therapy (aCRT) algorithm might enhance the efficacy of CRT. A 71-year-old female was admitted with the diagnosis of heart failure.

New methods for the analysis of heartbeat behavior in risk stratification

Frontiers in Physiology, 2011
Developing better methods for risk stratification for tachyarrhythmicsudden cardiac remains a major challenge for physicians andscientists. Since the transition from sinus rhythm to ventriculartachycardia/fibrillation happens by different mechanisms in ...

Electrocardiographic markers of myocardial conduction and repolarization in Boxer dogs [PDF]

Pesquisa Veterinária Brasileira, 2020
: Electrocardiographic markers have been used in people to classify arrhythmogenic risk. The aims of this study were to investigate electrocardiographic markers of conduction and repolarization in Boxers and non-Boxer dogs, and compare such findings ...

Electrocardiographic surrogates of structural myocardial alterations in the Dorper sheep heart

Onderstepoort Journal of Veterinary Research, 2005
In this study we evaluated the validity of well-known human electrocardiographic markers of myocardial pathology in Dorper sheep. These markers include: the duration of the QRS complex of premature ventricular complexes (PVCs), the presence of ...
