An unusual cause of tachycardiomyopathy: incessant atypical AV nodal reentrant tachycardia induced by 1:2 AV conduction.
We report a 62-year-old female with cardiomyopathy mediated by incessant atypical atrioventricular nodal reentrant tachycardia, which was induced by 1:2 atrioventricular conduction. Her arrhythmia was identified and cured by radiofrequency catheter ablation. Follow-up over the course of next 5 months the patient's cardiomyopathy dramatically improved.
