A case of tachycardia-induced cardiomyopathy due to chronic ectopic atrial tachycardia.
Only a few reports exist that chronic supraventricular tachycardia causes ventricular dilation and poor left ventricular contraction--so-called "tachycardia-induced cardiomyopathy." Clinical and electrophysiologic features of chronic supraventricular tachycardia including chronic persistent ectopic atrial tachycardia (EAT) in adults have also been described by a few investigators. 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.
