Gradation of the reflex response from atrial receptors.

Abstract

1. In anaesthetized dogs, distension of balloons so as to stimulate atrial receptors resulted in a reflex increase in heart rate. 2. Successive distensions of one, two and three balloons positioned in the left upper and middle pulmonary vein-atrial junctions and in the left atrial appendage resulted in a progressive increase in the magnitude of this response. 3. It is concluded that the magnitude of the increase in heart rate is related to the extent of receptor area stimulated.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

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.
