SVC-ERP in humans
Although SVC-ERP measurements in sheep 14 and dogs15 have been reported previously, to the best of our
knowledge, there are very few reports that have examined the SVC-ERP in
humans in detail. During the course of our study, we could only find one
relevant study 16. They investigated 20 patients with
paroxysmal supraventricular tachycardia and reported that the SVC-ERP
conducted by a basic drive cycle of eight stimuli at a cycle length of
600 was 266±17.3. However, the SVC-ERP in all AF patients in our study
was 280.0±49.0 in the anterior, 269.2±46.0 in the septal, 272.1±45.0 in
the posterior parts, and the average SVC-ERP was 273.8±43.4 ms. The mean
dispersion of the SVC-ERP was 32.1±22.0. Since there may be several
factors that can modify the SVC-ERP (e.g. electrical remodelling,
ganglionated plexi, and antiarrhythmic drugs), the measurement of the
SVC-ERP in healthy subjects must be included as a control.
