Figure 1. Type A Wolff-Parkinson-White (WPW) syndrome in Case 1. (A) Twelve-lead surface electrocardiogram (ECG) findings consistent with type A WPW syndrome. (B) Mapping of intracardiac potentials revealed that the site of earliest activation was adjacent to the lateral mitral annulus in an accessory pathway with both antegrade and retrograde conduction. (C) Atrioventricular reciprocating tachycardia was easily induced by programmed stimulation. HRA – high right atrium; CS – coronary sinus (1–2 distal; 9–10 proximal); paper speed 100 mm/s.
