However, both forms of A-V block were evidently dependent upon significant distal conduction system disease; this consideration was felt to warrant permanent pacemaker implantation. WebbThe electrophysiological hallmark of JT is the presence of a His bundle electrogram that precedes the QRS complex. The HV interval is either normal or prolonged (in the setting of infra-Hisian conduction system disease). A short HV interval in association with a narrow QRS complex (<35 ms) should prompt suspicion for fascicular tachycardia.
