阵发性心动过速的病人,常因心排血量减低引起其它的临床问题。心动过速发作时常伴有各种症状,严重者可危及生命。心动过速的发生大多是激动折返造成的。治疗方法可采用药物,外科手术或植入起搏器。药物治疗法有缺点,如导致不良的血液动力学反应,药物携带不便,易忘,还可能有致畸作用。外科去除术无论开胸术如切断异常通道,或应用导管进行电灼,只对部分病人有效或仅起缓解作用。起搏技术较外科手术简单,对多种心动过速有效,没有药物或外科手术带来的缺点。增加心率或调节心脏激动序列,起搏器可终止心动过速。
Patients with paroxysmal tachycardia, often due to reduced cardiac output caused by other clinical problems. Tachycardia often accompanied by a variety of symptoms, severe cases can be life-threatening. The occurrence of tachycardia is mostly caused by the rejuvenation. Treatment can use drugs, surgery or implanted pacemakers. Drug therapy has shortcomings, such as leading to poor hemodynamic response, drug carrying inconvenience, easy to forget, but also may have teratogenic effects. Surgical removal regardless of thoracotomy, such as cutting off the abnormal passage, or the use of catheter electrocautery, only part of the patient effective or only play a relieving effect. Pacing is more surgical than surgery and effective for a variety of tachycardia without the disadvantages associated with drugs or surgery. Increase the heart rate or adjust cardiac activation sequence, pacemaker can terminate tachycardia.
