Peripartum cardiomyopathy presenting with complete heart block

A 33-year-old woman presented with unconsciousness and complete heart block 20 days postpartum. On admission, her blood pressure was 70/50 mmHg and heart rate was 30/min. Immediately, a temporary transvenous pacemaker was inserted via the right femoral vein and her blood pressure increased to 100/70 mmHg with restoration of consciousness. Echocardiographic examination showed reduced left ventricular systolic function. The following day, complete heart block resolved spontaneously to sinus rhythm with right bundle branch block. Ten days later, right bundle branch block resolved together with improvement in left ventricular ejection fraction. To our knowledge, a case of peripartum cardiomyopathy presenting with complete heart block has not been reported.
