A few months later he developed frequent syncopal attacks, during which the pulse rate fell to 28-31, with periods of pulselessness for 10-12 seconds. 几个月后,病人常发生晕厥,发作时脉搏减至28~31次/分,并有10-12秒无脉。
Positive criteria were syncopal attack, presyncope with systolic blood pressure less than 90 mm Hg and/ or heart rate below 60/ mm. 试验阳性标准为晕厥先兆伴收缩期血压<90mmHg(1mmHg=0.133kPa)和/或心率<60次/min。
The clinical indicators were consisted of the syncopal attacks, the time of first onset, predisposing factors ( motion, agitation or quiet, sleep, etc.), family history of sudden cardiac death, previous treatment. 临床资料包括患者是否出现晕厥和首次发作时间、晕厥的诱发因素(运动、情绪激动或安静、睡眠等)、是否有心源性猝死家族史及既往诊治情况等。
