Continuous Recording During Radiofrequency Ablation of the Slow Pathway While maintaining sustained slow pathway conduction by right atrial pacing at a 700-ms cycle length, the AH interval shortened gradually from 410 to 90 ms within 8 s after the onset (open arrow) of radiofrequency energy delivered to the slow pathway region. Numbers are AH intervals in milliseconds. A = atrial electrogram; ABL = ablation catheter; H = His electrogram; HBE = His bundle electrogram; HRA = high right atrium; S = stimulus artifact; T = time line; V = ventricular electrogram.
