起搏器工作方式的新编码过去一直沿用ICHD 起搏器编码。近要来Brownlee 等人建议使用一种新式的起搏器工作方式字母编码法以表述单腔和双腔起搏方式。该编码表面上看起来采用一分数形式,横线以上为心房的活动(atrial activity),横线以下为心室的活动(ventricular activity)。所用字母的含义是:O=该心腔(心房或心室)内无起搏活动,P=起搏(pacing),S=感知(sense),A=心房(atrum),V=心室(Ventrcle),I=抑制(Inhibition),I_A=因感知到心房的兴奋而抑制(起搏或脉冲发放),T=触发(Triggtr),T_A=因感知心房兴奋而触发(起搏和刺激)。Tv=因感知心室兴奋而触发(起搏和刺激)。例如一台编号为PSI_AI_v/PST_AI_v 的起搏器,表示该起搏器的功能是①起搏并感知双腔;③任一腔的兴奋被感知后均可抑制对心房的起搏;③感知心室的兴奋而抑制对心室的起搏;④当一个心
New codes for pacemaker operation have historically been coded with ICHD pacemakers. Recent approaches to Brownlee et al suggest using a new type of pacemaker working method, letter encoding, to characterize single-chamber and dual-chamber pacing. The code appears to have a fractional appearance on the surface, with atrial activity above the horizontal line and ventricular activity below the horizontal line. The meaning of the letters used is: O = No pacing activity in the heart chamber (atrium or ventricle), P = pacing, S = sense, A = atrum, V = Ventrcle , I = Inhibition, I_A = inhibition (pacing or pulsing) due to the perception of atrial excitability, T = Triggtr, T_A = triggering (pacing and stimulation) due to the perception of atrial excitability. Tv = Triggered by sense of ventricular excitation (pacing and stimulation). For example, a pacemaker with the serial number PSI_AI_v / PST_AI_v indicates that the function of this pacemaker is ① pacing and perception of double chambers; ③ excitability of any one chamber can inhibit pacing of the atria; ③ sensing of ventricular The excitement and inhibition of ventricular pacing; ④ when a heart
