We present the case report of a 22-year man, with incessant palpitations, chest pain, shortness of breath, and pulsations in his neck for the past 7 months. He was referred to the cardiology unit for workup of wide complex tachycardia (WCT). His echocardiography, 6 months earlier, had demonstrated severe left ventricular (LV) systolic dysfunction, severe global hypokinesia, mild tricuspid regurgitation (TR), and mild mitral regurgitation (MR) which resolved with medical therapy including beta-blockers. He underwent electrophysiological study, which revealed a decremental right sided atriofascicular pathway causing a WCT with left bundle branch block (LBBB) morphology and left axis deviation (LAD, Mahaim tachycardia). This was successfully ablated by radiofrequency ablation (RF) with abolition of the tachycardia. This case report highlights Mahaim tachycardia induced cardiomyopathy, a rare but curable cause of cardiomyopathy.
