我院自1987年以来对临床符合北京地区诊断标准的窦房结功能不全者进行食道心房调搏窦房结功能测定。其中3例各项指标均未超过正常标准,考虑为迷走神经张力增高所致,报告如下。病例报告例1,男,20岁,战士。活动后胸闷、心悸、头昏半年。查超声心动图及X线胸片正常;心功能检查正常;心电图:心率45次/分;阿托品试验阳性.窦房结固有频率(IHR):80次/分,IHR后1小时内行食道调搏:窦房结恢复时间(SNRT):1490ms,校正窦房结恢复时间(CSNRT):170ms,窦房结恢复时间指数(SNRTI):112.9%,迷走神经总张力:-0.44。
Our hospital since 1987, the clinical diagnostic criteria consistent with the Beijing area of sinus node dysfunction, the esophagus atrial tachycardia sinus node function measurement. Three of these indicators did not exceed the normal standard, consider vagus nerve tension increased, the report is as follows. Case report 1, male, 20 years old, warrior. Chest tightness after activities, heart palpitations, dizziness for six months. Check echocardiography and normal chest X-ray; normal cardiac function test; ECG: heart rate 45 beats / min; atropine test positive.SNR: 80 beats / min IHR within 1 hour after esophageal pacing (SNRT): 1490 ms, corrected sinus node recovery time (CSNRT): 170 ms, sinus node recovery time index (SNRTI): 112.9%, total vagal nerve tension: -0.44.
