Atrioventricular nodal reentrant tachycardia (AVNRT), caused by a reentry circuit involving fast and slow atrioventricular nodal pathways, is one of the most common types of paroxysmal supraventricular tachycardias. While familial Wolff-Parkinson-White syndrome has been well recognized, familial AVNRT has been rarely reported. We report a familial occurrence of AVNRT in a mother and her son, who were symptomatic and successfully treated with radiofrequency catheter ablation of slow pathway.

BRASH syndrome is an acronym for Bradycardia, Renal failure, AV blockade, Shock, and Hyperkalemia. It arises from the synergy between AV nodal blocking medications (such as beta-blockers or calcium antagonists), renal failure, and hyperkalemia, leading to bradycardia and renal hypoperfusion. This exacerbates the decline in renal function and hyperkalemia, increasing the effect of AV-node blocking medication and creating a vicious cycle with the risk of multi-organ failure.

Scrub typhus, a common febrile illness in South Asia, can rarely cause life-threatening myocarditis with complete heart block. We report a 43-year-old man presenting with a one-week history of fever, shortness of breath, and abdominal pain. Laboratory findings showed transaminitis, hypoalbuminemia, elevated C-reactive protein, and mild hypokalemia, suggesting an infectious etiology.

Background: Bradycardia, renal failure, atrioventricular nodal blockade, shock, and hyperkalemia (BRASH) syndrome is an acronym used to describe a constellation of BRASH. It is an underrecognized phenomenon that can be deadly if not appropriately managed in a timely manner. This case highlights the importance of rapid diagnosis and reviews a multitude of treatment options in a uniquely severe case of BRASH syndrome.

Background: Mitral isthmus block (MIB) complicating radiofrequency ablation (RFA) of orthodromic reciprocating tachycardia (ORT) using left - sided accessory pathways (APs) is poorly understood.
Methods: Two cases and a systematic review of the literature of patients (pts) who developed MIB complicating left - sided ORT RFA is presented.
Results: Among 27 pts (34 ± 12 years old, 54% female, 68% concealed AP), 15 (56%) had ≥ 1 failed RFA procedure.
