QRS complex widening due to loss of left bundle branch capture: pitfall of para-Hisian pacing
During para-Hisian pacing, widening of the paced QRS complex usually indicates loss of His bundle capture. We describe a patient without any accessory pathways in whom widening of the paced QRS complex occurre...

Macroreentrant atrial tachycardia with an isolated pathway mimicking focal activation on three-dimensional electroanatomical map**
A 76-year-old man with two different sustained atrial arrhythmias that occurred after coronary artery bypass grafting underwent electrophysiological studies. Macroreentrant atrial tachycardias were detected wi...

Radiofrequency catheter ablation for atrial tachycardia originating from the left atrial appendage
A 36-year-old woman presented with drug-refractory atrial tachycardia. During the tachycardia episodes, P waves were positive in leads II, III, aVF, and V1, while they were negative in leads I and aVL. It was ...
