Why the study?
Although studies and case reports have investigated the familial and genetic features of AVNRT, these mechanisms remain unclear.
This case report highlights the potential familial and genetic features of AVNRT by presenting a mother and daughter with simultaneous attacks.

Does not warrant family screening for AVNRT; leaves open a possible genetic basis requiring validation.
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.
