阵发性室上性心动过速(PSVT)发作时,常有心悸、心前区不适或心绞痛、眩晕,持续时间长而严重者可有血压下降、心力衰竭及昏厥。过去我们采用压迫颈动脉窦或其它刺激迷走神经的方法,对少数患者有效,抗心律失常药物虽对大部分患者有效,但毒副作用大,尤其对病理机制不明又急需转复的PSVT给选择药物带来困难。1992年8月～1994年7月,我院采用经食管心房调搏(TEAP)技术治疗PSVT 39例次(31例),取得满意效果。
Paroxysmal supraventricular tachycardia (PSVT) attack, often palpitations, precordial discomfort or angina, dizziness, long duration and severe cases may have decreased blood pressure, heart failure and fainting. In the past we used oppression of the carotid sinus or other vagus nerve stimulation method for a small number of patients effective anti-arrhythmic drugs Although effective in most patients, but the toxic side effects, especially for the pathological mechanism of urgent need to rehabilitate PSVT to the choice of drug band Difficult to come. From August 1992 to July 1994, 39 cases (31 cases) of PSVT were treated by transesophageal atrial pacing (TEAP) in our hospital, and satisfactory results were obtained.
