Electrophysiological and epicardial mapping studies are described in a patient without pre-excitation who had intractable recurrent paroxysmal supraventricular tachycardia. Electrophysiological studies revealed fixed VA conduction times during both rapid ventricular pacing and coupled ventricular stimulation. Catheter mapping of atrial activation during retrograde conduction and during induced ...

The simultaneous occurrence of atrial and ventricular tachycardias, or junctional and ventricular tachycardias, has been reported previously. We report on a patient presenting with syncope and demonstrating, simultaneously, atrioventricular re-entrant tachycardia and ventricular tachycardia of left origin. A left lateral concealed pathway was responsible for the former arrhythmia, while the lat...

Abstract We report a case of left atrial hematoma after ablation lateral concealed accessory pathway. A 46-year-old male patient experienced chest pain radiofrequency ablation. Transthoracic echocardiography and computed tomography revealed the intramural mass consistent with in atrium. He was hemodynamically stable, conservative approach decided. Atrioventricular groove is vulnerable part atri...
