ABSTRACT
Although rare, long QT syndrome (LQTS) and peripartum cardiomyopathy (PPCM) are the major causes of maternal cardiovascular death. We herein present a case study of a 23-year-old woman with LQTS, pregnancy-induced hypertension, and PPCM. During the postpartum period, her left ventricular systolic function had severely decreased, requiring the administration of loop diuretics. Diuretics cause several changes in the circulating blood volume, electrolyte balance, and hormonal status during pregnancy, delivery, and the peripartum period. Extreme QTc prolongation and fatal ventricular arrhythmia require frequent defibrillation. For the patient in this study, we corrected her electrolyte abnormality, and eventually, we controlled the arrhythmia by administering a ß-blocker and Na-channel blocker. Although the arrhythmia subsided, she continued on medication after discharge to prevent the recurrence of fatal arrhythmia. In conclusion, close attention should be paid to patients with LQTS, especially when some changes that may lead to QTc prolongation could occur during the peripartum period.
