起搏频率是指1min内起搏器发放脉冲的次数,又称为基础起搏频率(Base Rate)。根据需要可通过程控仪调整、设定起搏频率。非频率适应型起搏器基础起搏频率恒定,频率适应型起搏器随着患者运动量的增加,起搏频率相应增快。单腔起搏器(AAI/VVI)如无自主心搏出现,依据程控的起搏频率发放脉冲。双腔起搏器随自主心房率的变化,可在多种起搏模式之间进行自动转换,与此同时,也增加了引发心室起搏频率过快的潜在因素。起搏器自动化功能的出现与发展,使起搏频率的变化也更加复杂。
Pacemaker frequency refers to the number of pacemaker pulse issued within 1min, also known as the basic pacing rate (Base Rate). According to the need to adjust through the programmer, set the pacing frequency. Non-frequency-responsive pacemaker basal pacing frequency constant, frequency-responsive pacemaker With patient movement increased, the corresponding increase in pacing frequency. Single-chamber pacemakers (AAI / VVI) In the absence of spontaneous beats, pulses are delivered based on programmed pacing rates. Dual-chamber pacemakers vary automatically with varying atrial rates to automatically switch between pacing modes and, at the same time, increase the potential for triggering ventricular pacing too frequently. The emergence and development of pacemaker automation make the change of pacing frequency more complicated.
