治疗心动过速的电起搏术有多种方法。对心动过速的机理,起搏器制止心动过速、减慢心室率的特点有所了解,有助于选用适当的治疗方法。电起搏术适用于药物治疗失败或不能用药物治疗,以及对某种电刺激有效应的心动过速。不论是环形运动型还是异位灶型心动过速,如果起搏位置接近心动过速的起源处,更易于抑制之。用快于基本心率的刺激以预防或消除心动过速,称为超速抑制。其机理可能为释放乙酸胆碱、释放钾、激活钠泵、增加心排出量.与冠状循环血流量、减小心脏容积从而减小心壁张力、以及非缺血性心脏于心率增快时减少应激性恢复的不均匀状态。这些效果都能抑制加速的异位起搏点,预防环形运动性心动过速。成对起搏、配对起搏、快速心房起搏可以不消除异位起搏点的活动,而改善心室功能及/或减慢心室率。心房起搏(心内膜、心外膜、冠状静脉窦、房间隔、食管)可中止或预防快速的室上性或室性心律失常。心室起搏(心内膜、心外膜、心肌、经胸)也同样有效。心室颤动必需电击除颤,心房颤动常需电击除颤,其他各种心动过速,几乎都可用人工起搏术消除之。单极或双极的起搏器可作临时性起搏,或埋藏作永久性起搏。用于消除室上性心动过速的起搏频率范围,从单次期前刺激到3600周/分交流电心房刺激。心脏人工起搏的方式,可以是按需的,或者是固定频率的。永久性埋藏的起搏器,可用体外磁铁、感应线圈、射频信号使它用作固定频率刺激。因此,心脏电起搏术是控制心动过速的一个重要技术。 There are many ways to treat electrical tachycardia with tachycardia. The mechanism of tachycardia, pacemaker to prevent tachycardia, slow down the characteristics of ventricular rate have some understanding, help to choose the appropriate treatment. Electric pacing is unsuitable for medical treatment or can not be treated with drugs, and tachycardia that is effective for some type of electrical stimulation. Whether circular or heterotopic tachycardia, pacing may be easier to suppress if it is near the origin of tachycardia. With faster than the basic heart rate stimulation to prevent or eliminate tachycardia, known as speeding. The mechanism may be the release of choline acetate, release of potassium, activation of the sodium pump to increase cardiac output and coronary blood flow, reduce the volume of the heart to reduce the wall tension, and non-ischemic heart rate decreases with increasing heart rate Uneven stress recovery. These effects can inhibit accelerated ectopic pacemaker, prevent circulatory motility tachycardia. Paired pacing, paired pacing, and rapid atrial pacing can improve ventricular function and / or slow down ventricular rate without disrupting ectopic pacemaker activity. Atrial pacing (endocardium, epicardium, coronary sinus, atrial septum, esophagus) can halt or prevent rapid supraventricular or ventricular arrhythmias. Ventricular pacing (endocardium, epicardium, myocardium, transthoracic) is equally effective. Ventricular fibrillation must shock the defibrillation, atrial fibrillation often require defibrillation, other kinds of tachycardia, almost all available artificial pacing to eliminate it. Monopolar or bipolar pacemakers can be used for temporary pacing, or buried for permanent pacing. Pacing for the elimination of supraventricular tachycardia frequency range, from a single pre-stimulation to 3600 weeks / min AC atrial stimulation. Artificial pacing of the heart can be on-demand, or fixed-frequency. Permanent buried pacemaker, available in vitro magnet, induction coil, RF signal it as a fixed-frequency stimulation. Therefore, cardiac electrical pacing is an important technique to control tachycardia.
