    What is a bundle extrasystole?
    His bundle extrasystoles manifest as “unexpected” heart block or PR interval prolongation and premature atrial and ventricular complexes. Intracardiac recordings can confirm the diagnosis by demonstrating spontaneous His bundle depolarization signals.

    Can a bundle extrasystole cause a heart block?
    His bundle extrasystoles may be concealed, causing physiological heart block, or manifest, typically associated with premature beats. To our knowledge, this is the first reported case of dual ventricular response manifesting as heart block. The diagnosis was ultimately established, based on results of the AV nodal slow pathway ablation.

    Does a dual AV node physiology favor his bundle extrasystole?
    Absence of a demonstrable dual AV node physiology during electrophysiology study should favor His bundle extrasystole. Consistent reproduction of the rhythm by atrial stimulation may suggest dual AV nodal response. The coupling interval of the premature beat can vary in both conditions.

    Does extrasystole normalize QRS complex morphology?
    His extrasystole peels back refractory period in the left bundle which resolves left bundle branch block and thus normalizes the QRS complex morphology. HV interval during sinus rhythm with left bundle branch block is 73 ms, with narrow is QRS 61 ms, and with extrasystole is 61 ms.

    How can a bundle extrasystole be differentiated from a premature atrial complex?
    His bundle extrasystoles can be differentiated from premature atrial complexes on the surface ECG as the His extrasystole is not preceded by a P wave. His extrasystoles occur because of abnormal automaticity within the His-Purkinje system.

    Is dual AV nodal ventricular response a differential diagnosis of his bundle extrasystole?
    Dual AV nodal ventricular response, a condition readily amenable to ablation, should be routinely considered in the differential diagnosis of His bundle extrasystole. None. St Vincent Medical Group, 8333 Naab Road, No. 400, Indianapolis, IN 46260
