Özet
A59?year?old man underwent a diagnostic electrophysiology studybecause of rapid palpitations and documented supraventriculartachycardia (SVT) unresponsive to metoprolol therapy. His 12?leadelectrocardiogram was normal. Baseline atrio?His and His?ventricularintervals measured 48 and 48 ms, respectively. Programmed atrialextrastimulation using single atrial extrastimuli repeatedly induced hisSVT. The response to His refractory ventricular extra stimulations(Hr?VESs) is shown in Figure1. Based on the information, what arethe mechanisms of his tachycardia and apparently discordantresponses?
