Normal conduction intervals and responses in sixty-one patients using His bundle recording and atrial pacing.

Abstract

In the present study, His bundle electrograms (H) were recorded in 61 patients without evidence of conduction disease on the surface el ‘cfrocardiogram, in order to establish the normal range of conduction intervals. The conduction intervals (in msec) were as follows (mean ± 2 SD): P-H 1 19 ± 1 19 ± 38; P-A 27 ± 18; A-H 92 ± 38 and H-V 43 ± 12. Afrial… (More)
