This article reports a follow-up study of 56 patients with second-degree AV block. Methods: 56 cases of second degree AV block patients, 46 males and 10 females, aged 18-87 years. The selection criteria were: (1) electrocardiogram with second degree AV block; (2) multiple ECG prompts for chronic manifestations; and (3) electrophysiological examination as second degree AV block (AH interval prolongation> 130 ms). When the atrial pacing frequency was <101 beats / min or the AV node should be prolonged (AVS effective refractory> 365 ms and / or AV node refractory> 495 ms). 19 cases without organic heart
