Audible atrial contractions were recorded in a case of rheumatic heart disease during atrial fibrillation and the transition stage to atrial flutter. With coarse atrial fibrillation these correlated ...

Atrial fibrillation is the most common chronic arrhythmia. It is characterized by erratic atrial electrical activity with atrial rates of 400 to 600 beats per minute. The P wave is absent on the ...

This work shows the two independent structures of cardiac amyloids formed by non-native atrial natriuretic peptide (ANP) dimers extracted from atrial fibrillation patients. These data point at dimeric ...

Atrial cardiomyopathy is a condition that causes electrical and contractile dysfunction of the atria, often along with structural and functional changes. Atrial cardiomyopathy most commonly occurs in ...
