Severe Heart Failure Associated With Tachycardia-Induced Cardiomyopathy Due to Incessant Atrioventricular Re-Entrant Tachycardia

  Figure 1. Patient 1 Electrocardiograms and Chest Radiography (A) Initial electrocardiogram: regular narrow QRS complex tachycardia (180 beats/min) with short RP interval (RP<PR) and RP >90 ms. (B) Recurrent onset of the tachycardia after termination by adenosine injection. (C) Chest radiography: bilateral venous congestion and alveolar edema.

  Figure 2. Patient 2 Electrocardiograms (A) Initial electrocardiogram: regular narrow QRS tachycardia (170 beats/min) with short RP interval (RP<PR) and RP >90 ms. (B) Tachycardia restarted in an antidromic form after adenosine injection. Positive V1, negative D1-aVL, and positive inferior leads suggest a left anterolateral accessory pathway.
