We examined the clinical features, 12-leads ECG, Holter ECG, monitor ECG, and electrophysiologic study (EPS) in nine consecutive paroxysmal atrioventricular block (PAVB) patients treated in our hospital between 1995 and 2000. In some of them, parasympathetic nerve stimulating maneuvers, drug administration and head-up tilt test (HUT) were performed as provocative tests. EPS documented that the sites of AV block were within the His-Purkinje system (H-PSB) in five patients, proximal to the His bundle potential (AHB) in three patients. In the remaining one patient, the His bundle potential was not recorded. The main features of the patients with H-PSB were as follows: 1) often wide QRS complex with or without axis deviation; 2) variable degrees of AV conduction disturbance in a short period; 3) sinus tachycardia, and normal length and constant PQ intervals in a daytime being apt to precede PAVB; 4) rather long ventricular asystoles leading to abrupt syncope; 5) easy induction of the block by intravenousadministration of atropine. In the other hand, the features of the patients with AHB included: 1) narrow QRS; 2) progressively increasing or decreasing in PQ intervals preceding PAVB; 3) ventricular asystole lasting about 3 to 10 seconds; 4) the failure to induce PAVB by any probale provocative tests.<BR>Although we treated all the patients with permanent pacemakers, there might have been other management method for AHB patients who had about 3-second ventricular asystole.
