工作完全正常的埋藏式心脏起搏器在植入病员体内后,至关重要的是起搏器电池的寿命,它不仅决定起搏器的更换时间,也关系到病员的安危。随着起搏器工作时间的延长,其供电电池的电压必然会下降,这将影响起搏器输出脉冲的性能。起搏器的核心部件是脉冲振荡器,当供电电压下降时,振荡器的输出脉冲幅度(或功率)、输出脉冲宽度及其重复频率都会发生变化。凡起博器,输出脉冲幅度的下降和电池电压的下降是成正比的,而其输出脉冲宽度和重复频率的变化与电池电压的下降却不成比例。有的起搏器的电池电压下降30%,输出脉
Working fully normal buried cardiac pacemakers in the patient after implantation, the most important is the life of the pacemaker battery, which not only determines the pacemaker replacement time, but also relates to the safety of the patient. As the working pace of the pacemaker prolongs, the voltage of the power supply battery will inevitably decline, which will affect the performance of the pacemaker output pulse. The heart of a pacemaker is a pulse oscillator. When the supply voltage drops, the oscillator output pulse amplitude (or power), the output pulse width and its repetition frequency change. Where pacemakers, the drop in output pulse amplitude is proportional to the drop in battery voltage, and the variation in output pulse width and repetition frequency is out of proportion to the drop in battery voltage. Some pacemakers battery voltage dropped 30%, the output pulse
