Approach Considerations

Assess serum electrolyte levels, particularly potassium, in all patients with acute arrhythmias.

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

Echocardiography has become the standard diagnostic modality to assess chamber enlargement, left ventricular (LV) wall motion abnormalities, hypertrophy, valvular disease, and systolic dysfunction. In patients at risk for coronary artery disease, additional cardiac imaging (eg, perfusion imaging, echocardiography) may be required.

Upon resolution of holiday heart syndrome and return to sinus rhythm, treadmill stress testing is reasonable in some patients to look for exercise-related arrhythmia after the acute effects of alcohol have resolved.
