临床及食管电生理资料例1 男性,30岁。有阵发性心动过速史10年,每次发作历时散分钟至数小时。呈突然发作和消失,多与情绪波动和劳累有关,发作时常感心慌、胸闷、头晕。查体:一般情况好,Bp14.6/10.6kPa(110/80mmHg),心界不大,心率78次/分,律齐,未闻及病理性杂音。心电图、X线胸片、超声心动图及室验室检查未见异常。食管心房调搏窦房结恢复时间及窦房传导时间正常。程序心房电刺激检查:S_1S_1550ms,S_1S_2以10ms为步长从530ms开始递减反扫,可见随S_1S_2缩短,S_2R逐渐延长,当S_1S_2为290ms时,S_2R为280ms(R_2后有逆P′,R-P′140ms可能为循慢径路逆传折返所致);S_1S_2为280ms时,S_2R为380ms;S_1S_2为270ms
Clinical and esophageal electrophysiology data example 1 male, 30 years old. Have a history of paroxysmal tachycardia for 10 years, each attack lasted from minutes to hours. Was a sudden attack and disappear, and more with mood swings and exertion, seizures often feel flustered, chest tightness, dizziness. Physical examination: the general situation is good, Bp14.6 / 10.6kPa (110 / 80mmHg), heart is not, heart rate 78 beats / min, law Qi, no smell and pathological murmur. Electrocardiogram, X-ray, echocardiography and laboratory tests showed no abnormalities. Esophageal atrial pacing sinus node recovery time and sinoatrial conduction time is normal. Procedures of atrial electrical stimulation examination: S_1S_1550ms, S_1S_2 in 10ms steps from 530ms back anti-sweep, showing S_1S_2 shortening, S_2R gradually extended when S_1S_2 290ms, S_2R 280ms (R_2 after the inverse P ’, RP’ 140ms Which may be caused by retrograde reversion caused by slow path); when S_1S_2 is 280ms, S_2R is 380ms; S_1S_2 is 270ms
