A 12-Lead Electrocardiogram Demonstrating His Capture The electrocardiogram and His signal from a single patient is shown (these data are displayed for all participants in the Online Appendix). (Left) The QRS morphology during intrinsic conduction and a series of different atrioventricular (AV) delays produced with His pacing are shown in the right 5 panels. The His-to-V delay is displayed (red lines in left panel) and pacing stimulus to V delay is shown during His pacing with an AV delay of 40 ms. At an AV delay of 200 ms, an intrinsic His deflection is seen before the ventricular pacing artifact, suggesting that ventricular activation has occurred as a result of intrinsic conduction rather than His pacing.
