Approach Considerations

Assess serum electrolyte levels, particularly potassium and magnesium, in all patients with acute arrhythmias. Hypomagnesemia and hypokalemia are common in alcoholics, particularly on presentation to the hospital. [32]

Twelve-lead electrocardiography (ECG) is essential to exclude other cardiac pathology such as ischemia, infarction, pulmonary embolism, or hypertrophy.

Echocardiography is the standard of care for assessment of cardiac chamber enlargement, left ventricular (LV) wall motion abnormalities, hypertrophy, valvular disease, and both systolic and diastolic dysfunction. In patients at risk for coronary artery disease, additional cardiac imaging (ie, perfusion imaging) may be required.
