How To Differentiate Right Ventricular Outflow Tract Tachycardia
... Electrophysiological studies (EPSs) may help to differentiate RVOT tachycardia due to ARVC from idiopathic RVOT-VT. In the setting of ARVC, the signals of the endocardial electrograms may be significantly altered in terms of activation delay, fragmentation, amplitude decrease, or dense scarring. The ...
