Abstract

In anesthetised cats, following vagal stimulation with short bursts of pulses, a narrow zone was identified within the cardiac cycle where even a small change of the vagal burst position produced sharp alterations in the magnitude of the chronotropic effect. Somatostatin diminished the size of this zone whereas its antagonist exerted an opposite effect.

Cardiac Electrophysiology

Cardiac electrophysiology is the study of electrical activities of the heart and includes the assessment, diagnosis, and treatment of cardiac events. Find the latest research on cardiac electrophysiology here.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
