Premature Atrial Contractions: Causes & Reasons

Possible Causes for Premature Atrial Contractions

In several patients there seemed to be a transition from multifocal premature atrial contractions through chaotic atrial tachycardia to atrial fibrillation. [ahajournals.org]

Six patients had 3 to 6 premature atrial contractions per minute. No adverse effects were noted, and arterial blood gases before and after therapy were comparable. [ncbi.nlm.nih.gov]

Unifocal or multifocal premature atrial contractions preceded the arrhythmia in 20 cases (64%). The arrhythmia developed during an acute illness in 18 cases (58%). [ahajournals.org]
