Abstract: Introduction Different morphologies of focal right ventricular (RV) tachycardia displaying left or right axis deviation of the QRS complex imply 2 distinct arrhythmic sources and raise suspicion of underlying structural heart disease. A single RV… read more here.

Abstract: BACKGROUND Intraoperative mapping has demonstrated focal activations during human atrial fibrillation (AF). These putative AF sources can manifest sustained periodic bipolar and unipolar QS electrograms (EGMs). We have automated the detection of these EGM features… read more here.
