EKG of the Week 2017 4-16

This EKG comes courtesy of Dr. Altberg.

A 19 year old male presents to the ED intoxicated. He also complains of palpitations. His EtOH level is 261. (This is equivalent to a blood alcohol content of 0.26).

His vital signs are: Pulse 140, Respirations 18, BP 120/80.

His EKG is below.

1.       What does the EKG demonstrate?

2.       How would you manage this patient?

ANSWER:

The EKG demonstrates atrial fibrillation. In the setting of acute alcohol intoxication, this is known as Holiday Heart Syndrome.

The heart rate is normal. No specific interventions are necessary. The patient should be observed on telemetry until the a-fib resolves.

 

Patients who “binge drink” are at risk for supraventricular arrhythmias, with atrial fibrillation being the most common. It can also cause atrial flutter, atrial tachycardia, and PVC’s. These patients are typically healthy with no past history of cardiac disease. When they stop drinking, the symptoms go away. This is known as Holiday Heart Syndrome. The arrhythmias can occur at the time of drinking or up to 36 hours later.

Patients with Holiday Heart Syndrome typically present with palpitations. They may also have chest pain and syncope. There are several mechanisms that have been proposed to explain why Holiday Heart occurs.

Initial treatment of patients with Holiday Heart is the same as other patients with atrial fibrillation. If they are tachycardic, their rate should be controlled with AV nodal blockers. However, they are typically at low risk for clots and usually do not require anticoagulation. Rhythm control is usually unnecessary as the arrhythmia usually resolves spontaneously within 24 hours. They should be admitted to a monitored setting.
