本文用非侵入性食道心房调搏方法,检测了151例老年前期非病窦者的窦房结功能,报道如下。对象选择与检测方法1.一般资料:老年前期151例,男80例,女71例.年龄50～59岁,平均55.2岁.选择对象(1)既往无晕厥史;(2)无严重窦性心动过缓(<50次/分);(3)常规心电图无窦性静止、窦房阻滞和快慢综合征表现.2.方法:受检者不用镇静剂,经鼻腔送入双极起搏导管,根据食道心电图示双相高大P 波时作电极定位,无须X 线透视.平均起搏压28伏。起搏时,
In this paper, non-invasive esophageal atrial pacing method was used to detect the 151 cases of senile elderly patients with sinus node dysfunction, reported as follows. Object selection and testing methods 1. General information: 151 pre-senile patients, 80 males and 71 females, aged from 50 to 59 years, mean 55.2 years old. Subjects (1) no previous history of syncope; (2) no serious sinus Bradycardia (<50 beats / min); (3) conventional electrocardiogram no sinus quiescence, sinoatrial block and the performance of fast and slow syndrome .2 method: the subjects without sedatives, transnasal bipolar pacing catheter , According to esophageal ECG showed biphasic high P wave for electrode positioning, no X-ray. The average pacing pressure 28 volts. When pacing,
