Yes: Dehydrating and electrolyte depletion can result from excess alcohol consumption. Low potassium can lead to heart arrhythmias.

Damage heart: Alcoholism does not cause low potassium. Rather it can cause magnesium deficiency. Alcohol is very toxic to heart muscle in some individuals and can cause alcoholic cardiomyopathy which can then lead to heart failure and serious issues.
