Reproducibility of the electrophysiologic examination



Reproducibility of the electrophysiologic examination



Tokyo Jikeikai Medical Journal 99(5): 817-832



The reproducibility of the electrophysiologic examination was examined in 29 patients with paroxysmal supraventricular tachycardia (PSVT). The examination was performed repeatedly, more than twice for each patient. The collected informations include: the inducibility of PSVT and the width of its echo zone, the atrial effective refractory period (AERP), sinoatrial conduction time (SACT) and sinus node recovery time (SRT) and the relationship between the inducibility of PSVT during examinations and clinical symptoms (the frequency and the duration of the PSVT attack). During serial examinations, echo beats were induced repeatedly in 26 of 29 patients (90%). Sustained PSVT was induced each time in 15 of 18 patients (83%) with accessory pathway reentrant tachycardia (AP-RT) and in 6 of 10 patients (60%) with atrioventricular nodal reentrant tachycardia (AVN-RT). The reproducibility was thus lower in AVN-RT group than in AP-RT group. In the latter, the longer the preexamination sinus cycle length was, the less frequent the PSVT induction became. The change in the autonomic nervous system tone apparently would have influenced the reproducibility of the induction of sustained PSVT. The inducibility of sustained PSVT was higher at the initial examination (in the catheter laboratory) than at the following examinations (in the sick room). This also seemed to indicate effect of the autonomic nervous tone on the inducibility of sustained PSVT. The repeated measurement of the width of the echo zone and of SACT was almost constant each time, and thus the reproducibility was high in these measurements. The inducibility of PSVT during serial examinations was closely related to the frequency of tachycardia attack in daily life. The results of the electrophysiologic examinations evidently were reproducible and reliable in diagnosis and treatment of various arrhythmias.
