Tako-tsubo cardiomyopathy following complete atrioventricular nodal heart block during transcatheter radiofrequency ablation of atrioventricular nodal reentrant tachycardia.

We report a case of tako-tsubo cardiomyopathy after an unintentional atrioventricular (AV) block during an ablation procedure in a 77 year-old woman. This intriguing case explores three possible reasons that could have triggered the disease: (1) slow pathway destruction; (2) AV nodal complete heart block; (3) the overall stress the patient had experienced.
