What is the effect of large amounts of alcohol on the heart?

Immediate effect of an alcoholic binge is development of atrial fibrillation, an irregular fast heart beat, also known as “Holiday Heart Syndrome”. This occurs mostly in those individuals prone for it.

Long term use of alcohol in large amounts weakens the heart muscle leading to alcoholic cardiomyopathy, a form of dilated cardiomyopathy (heart muscle disease) eventually leading to heart failure.
