贲门癌伴窦性心动过缓的原因及其手术治疗

Occurrence and Surgical Treatment of Cardiac Carcinoma with Sinus Bradycardia

目的 探讨贲门癌伴窦性心动过缓的原因及其手术治疗方法。方法 对 1996年 1月至 2 0 0 3年 3月伴有窦性心动过缓的 82例贲门癌患者的临床资料进行分析。结果 全组均安全耐受麻醉并行手术治疗 ,手术切除率为 98.8% ( 81/82 )。术中心率5 5～ 79次 /min 3 1例 ,80～ 99次 /min 41例 ,10 0次 /min以上 10例 ;术后 1周内 ,心率 60～ 79次 /min 2 1例 ,80～ 99次 /min 61例 ;术后 1～ 2周间 ,心率 60～ 79次 /min 3 4例 ,80～ 10 0次 /min 48例。结论 贲门肿瘤压迫、刺激使迷走神经张力增高可能是导致窦性心动过缓的主要原因 ;术前准备充分 ,术中。

Objective To investigate the occurrence and surgical treatment of cardiac carcinoma with sinus bradycardia.Methods From January 1996 to March 2003,the data of 82 patients with cardiac carcinoma who had sinus bradycardia and underwent surgical treatment were analyzed.Results All the patients tolerated anesthesia and operation with a resectability of 98.8%(81/82).During the operation,the heart rate(HR) was 55～79/min in 31 cases,80～99/min in 41 cases and >100/min in 10 cases.Within one week after operation,the HR was 60～79/min in 21 cases,80～99/min in 61 cases.From the first to second week after operation,the HR was 60～79/min in 34 cases,80～100/min in 48 cases.Conclusion The compression and stimulation to Vagus nerve by the mass of cardiac carcinoma increases the excitability of Vagus nerve.That may be the main reason of the occurrence of sinus bradycardia.Sufficient preoperative preparation and apropriate managements during and after surgery are the key to the success of operation for the patients with cardiac carcinoma combined with sinus bradycardia.
