ECG and arrhythmias in peripartum cardiomyopathy.

Peripartum cardiomyopathy (PPCM) is a rare but life-threatening heart disease, with onset in the last month of pregnancy or in the first months after delivery. Extensive studies on the burden of supraventricular and ventricular arrhythmias are lacking. Patients with PPCM present with electrocardiographic findings typical in acute heart failure. Management of arrhythmias in PPCM depends on the severity and the onset (during pregnancy or after delivery). Studies on the use of the wearable cardioverter-defibrillator in patients with PPCM show a substantial burden of ventricular tachyarrhythmias and sudden death in patients with severely reduced left ventricular function. The aim of the present article is to summarize actual knowledge on electrocardiogram findings, arrhythmias, and sudden cardiac death in patients with PPCM.
