The atrial electrocardiogram was studied in eight patients who developed intermittent atrial fibrillation following myocardial infarction. Thirty-two episodes of onset of atrial fibrillation and 28 episodes of spontaneous cessation were observed. An atrial premature beat followed by atrial tachycardia of variable duration always preceded the onset of atrial fibrillation. Spontaneous cessation o...

Atrial fibrillation (AF) and hypertrophic cardiomyopathy (HCM) are two very common clinical entities, which often occur simultaneously, giving a hard time to both patients cardiologists. Myocyte hypertrophy, myocyte disarray interstitial fibrosis in the left atrium (LA) predisposes atrial arrhythmias due modifications of substrate that promote re-entry. AF is usually poorly tolerated shortening...
