Fig. 3From: Postoperative supraventricular tachycardia and polymorphic ventricular tachycardia due to a novel SCN5A variant: a case report of a rare comorbidity that is difficult to diagnoseElectrophysiological study. a The right anterior oblique (RAO) and left anterior oblique (LAO) projections showing the electrode positions. The ABL electrode is at the upper edge of the scar in the right atrium. b The post-pacing interval from the ABL electrode at the upper edge of the scar matched the cycle length of the tachycardia (left). Arrows indicate the 280-ms burst pacing from the ABL electrode. Radiofrequency ablation promptly terminated the tachycardia (right)Back to article page
