35例阵发性室上性心动过速患者,年龄16～69岁,平均35岁。以程序电极刺激诱发后,再随机施以4种物理手法终止:即右颈动脉窦按摩5 sec,左颈动脉窦按摩5sec;面部浸入5～7℃冷水(潜水反射)15～20sec;仰卧位和立位Valsalva动作(向压力计吹气达35mmHg,持续15～30sec,吹气前不能深吸气)。每种手法重复3次,若有2次能终止心动过速者判为有效。
35 patients with paroxysmal supraventricular tachycardia, aged 16 to 69 years, mean 35 years. After programmed electrode stimulation, the animals were randomly divided into four physical methods: the right carotid sinus massage for 5 sec and the left carotid sinus massage for 5 sec; the facial immersion for 5 ~ 7 ℃ cold water (subcutaneous reflex) for 15-20 sec; the supine position And standing Valsalva action (blow the pressure gauge up to 35mmHg for 15 ~ 30sec, do not inspiratory deep before blowing). Each method repeated 3 times, if there are 2 times to terminate the tachycardia sentenced to be valid.
