Brownlee等人提出一种新的起搏工作方式字母编码法,建议可用作国际心脏学会议(ICHD)编码的一种补充以表述单心腔和双心腔起搏器的工作方式。该编码横线以上通常系指心房,横线以下指心室。所用字母的含义,如在单腔单元内,O表示该腔内无起搏活动,P表示起搏,S表示感知,I_A表示因感知到心房的活动而抑制,I_V表示因感知到心室的兴奋而抑制。如一台起搏器的型号为PSI_AI_V/PSI_AI_V则表示双腔起搏并感知;任一腔的兴奋被感知后均可抑制对心房的起搏;通过感知心室兴奋而抑制心室的起搏;当一次心房的活动被感知后并经过一个予定的房(A)-室(V)延迟触发对心室的起搏。因此,即便是最复杂的起搏方式,
Brownlee et al. Proposed a new pacing method of alphabetic encoding that could be used as a supplement to the International Society of Cardiology (ICHD) coding to describe the workings of single and double cardiac pacemakers. The code above the line usually refers to the atrium, below the horizontal line refers to the ventricular. The meaning of the letters used is, for example, in a single chamber unit, O indicates no pacing activity in the lumen, P indicates pacing, S indicates sensation, I_A indicates inhibition due to perceived atrial activity, and I_V indicates ventricular activation due to sensation of ventricular activation And inhibit. For example, the type of a pacemaker is PSI_AI_V / PSI_AI_V, which indicates pacing and perception of the double chamber; the pacing of the atrium can be inhibited after the excitement of any one chamber is sensed; the pacing of the ventricles is suppressed by sensing the ventricular activation; After atrial activity is sensed and passes through a given chamber (A) - chamber (V), the pacing of the ventricles is triggered. Therefore, even the most complex pacing mode,
