【 摘 要 】

History of cardiac pacing began in the 1950s with the development ofpacemakers tethered to an extension cord.1 It was followed by the firstfully implantable pacemaker in Arne Larson in 1958 by Ake Senningand Rune Elmqvist. The original system lasted only for eight hours, andArne Larsson had to undergo over 20 pacemaker replacements, but heoutlived both his surgeon and device engineer.Since then, a remarkable collaboration among surgeons, physicians,engineers, businessmen, and patients has led to an extensive development in this field, including the development of leadless pacemakers.Today, there are three basic kinds of pacemakers: single chamber, dualchamber, or biventricular pacemakers.2 The common indications forpermanent pacemaker include sick sinus syndrome, symptomaticsecond- or third-degree atrioventricular blocks, bifascicular block,alternating bundle branch block, and recurrent syncope with ventricular asystole > 3 seconds. The modes of pacemaker are based on genericcodes known as NBG code and typically consists of 4- or 5-letter code,in which the first position identifies the chamber paced (A for atrium, Vfor ventricle, Dfor dual), the second position: chamber sensed, the thirdposition: device response to sensed events (I for inhibit, T for trigger,or D for dual), the fourth position: whether rate response is on, andthe fifth position (when used), indicates whether multisite pacing isemployed in the atrium (A), ventricle (V), or both (D).
