The design of a pacemaker which indicates the occurrence of significant bradyarrhythmia is described. Significant bradyarrhythmia is defined as either asystole for 6 seconds, bradycardia with three successive RR-intervals greater than 2 seconds each, or five or more RR-intervals of 2 seconds or more over a period of 25 seconds, but without three such intervals in succession. During bradyarrhythmia the generator initially stimulates at an interval of 2 seconds (30 per minute) and when the described criteria have been fullfilled the pacemaker automatically converts to a conventional ventricular inhibited pulse generator stimulating at a rate of 70 per minute.
本文描述了一种能够指示严重缓慢性心律失常发生的起搏器设计。严重缓慢性心律失常的定义为:心脏停搏6秒;心动过缓,连续三个RR间期均大于2秒;或在25秒内出现五个或更多2秒及以上的RR间期,但无连续三个此类间期。在缓慢性心律失常期间,起搏器最初以2秒的间期(每分钟30次)进行刺激,当满足所述标准时,起搏器会自动转换为传统的心室抑制型脉冲发生器,以每分钟70次的速率进行刺激。
