1 Wide complex tachycardia in a patient with pre-excitation: What is the mechanism?

3 Figure 2 A: Intracardiac electrograms during wide complex tachycardia. There is capture and reset of the atrial (“A”) and ventricular (“V”) electrograms following a late-coupled atrial premature beat (APB) from the high right atrium (HRA). There is also fusion and reset of the QRS on the surface electrocardiogram following the second APB without terminating the wide complex tachycardia. The increased local AV interval of the His bundle (His) and coronary sinus (CS) activation associated with the APBs demonstrate decremental delay. B: Overdrive pacing from the right ventricular apex (RVA) with local capture of the right ventricle and reset of the wide complex tachycardia, including reset of the last paced beat. The last paced and advanced complex is the atrial complex, followed by tachycardia continuing with an atrioventricular complex.
