Synchronized AVNRT attack of mother and daughter: case report

Abstract

Atrioventricular nodal reentrant tachycardia (AVNRT) is a common arrhythmia and accounts for approximately 45-65% of paroxysmal supraventricular tachycardias. Patients may present with palpitations, syncope, dizziness, nausea, or sudden cardiac arrest. Although a few studies and case reports investigate the familial and genetic features of AVNRT, these mechanisms are unclear. This report aims to present the cases of a mother and her daughter who contributed to the emergency department with simultaneous AVNRT attacks and draw attention to the familial nature of AVNRT.
