Only a few reports exist that chronic supraventricular tachycardia causes ventricular dilation and poor left ventricular contraction—so‐called “tachycardia‐induced cardiomyopathy.” 1‐4 Clinical and electrophysiologic features of chronic supraventricular tachycardia including chronic persistent ectopic atrial tachycardia (EAT) 5‐7 in adults have also been described by a few investigators. 5‐9 We report a rare case of long follow‐up of chronic EAT‐induced severe cardiomyopathy and mitral regurgitation that was well controlled after medical treatment.
