a. Sinus rhythm with short PR interval and fully pre-excited QRS with negative delta in V1, positive delta in leads II, aVF, isoelectric delta in lead III suggestive of right anterolateral free wall accessory pathway site of origin. b. loss of delta wave post ablation with narrow QRS and normal PR interval.

Pre-ablation ejection fraction measured by Simpsons method and LV dimensions in systole and diastole. A4Cd (apical four chamber in diastole), A4Cs(apical four chamber in systole), A2Cd (apical two chamber in diastole), A2Cs(apical two chamber in systole), PSLd (parasternal long in diastole), PSLs (parasternal long in systole).

Simultaneous intra-cardiac tracing and fluoroscopic image in left anterior oblique showing ablation catheter at site of successful ablation around the tricuspid annulus at 10-11 o clock (yellow arrow). RV-His catheter positioned with His signal (H) on His mid showing negative HV in first two beats and distal poles at right ventricular apex (dashed arrow). Deflectable decapolar coronary sinus catheter in the coronary sinus (solid black arrow). Surface lead I, II and V2 showing resolution of delta wave and AV signal fusion during ablation (Red arrow). HV 5 msec post ablation.
