摘要： A variable rate defibrillator charging circuit includes a power transformer that accepts an internal battery output and the output from an AC-to-DC converter on separate primary windings. The secondary winding of the transformer is coupled through a rectifier to a storage capacitor. The transformer operates in a fly-back mode whereby energy is discharged into the storage capacitor when the power supplies discontinue charging the transformer. After energy in the transformer is discharged into the storage capacitor, the power supplies are reactivated, recharging the transformer. The separate primary windings of the transformer provide a fast, reliable, low cost means for charging the storage capacitor with multiple power supplies. The AC power source feeding the AC-to-DC converter is detachable allowing the defibrillator to be operated remotely whereby the storage capacitor is charged solely from the internal battery. The charging circuit monitors the output voltage levels of both the battery and the AC-to-DC converter and enables or disables the power supplies in accordance to their ability to charge the storage capacitor within a predetermined amount of time. The energy in the storage capacitor, which is eventually discharged into a patient, is monitored to prevent overcharging.
摘要翻译：可变速率除颤器充电电路包括接收内部电池输出的电力变压器和在单独的初级绕组上的来自AC-DC转换器的输出。变压器的次级绕组通过整流器耦合到存储电容器。变压器以回扫模式工作，当电源中断对变压器充电时，能量被放入存储电容器中。变压器内的能量被放入储存电容器后，电源被重新激活，对变压器进行充电。变压器的单独的初级绕组提供了一种快速，可靠，低成本的方法，用于对具有多个电源的存储电容器进行充电。馈电AC-DC转换器的AC电源是可拆卸的，允许除颤器远程操作，从而存储电容器仅从内部电池充电。充电电路监视电池和AC-DC转换器的输出电压电平，并根据其在预定时间内对存储电容器充电的能力启用或禁用电源。监测储存电容器中最终排放到患者体内的能量，以防止过度充电。

摘要： An automatic fibrillator for inclusion in an implantable defibrillator. Fibrillation induction takes place while the patient's heart is beating at a known rate, and the fibrillation inducing pulse is delivered at a time based on the expected or measured natural refractory period of the patient's heart, at the heart rate in effect during fibrillation induction. In its preferred embodiment, fibrillation induction takes place during overdrive pacing, and the timing of the pulse takes place using an overdrive pacing pulse as a time reference. The period between the pacing pulse and the fibrillation inducing pulse may be determined as a function of actual measurement of the patient's refractory period, either directory, or by means of measurement of the Q-T interval of the patient's heart.

摘要： A system for determining the defibrillation threshold energy of a defibrillation lead arrangement by shocking the heart during the T wave of the ECG at decreasing energy levels until the heart is placed in fibrillation. The lowest energy level tested which fails to place the heart in fibrillation correlates to the defibrillation threshold energy of the lead arrangement.

摘要： A cardiac stimulator apparatus for effecting cardioversion or defibrillation in the event of pathologic tachycardia or ventricular fibrillation in which the rate of heart depolarization signals is compared to a predetermined heart rate value indicative of the onset of tachycardia while, simultaneously, the heart's pre-ejection period is monitored to sense whether an increase in heart rate above the predetermined value is accompanied by a decrease in the pre-ejection period. If not, a pathologic rather than a physiologic episode is diagnosed and a cardioversion pulse protocol is initiated. By also monitoring the mechanical pulse of the heart, if an inordinately high heart rate is accompanied by a low or non-existing mechanical pulse, ventricular fibrillation is diagnosed and the cardioverter is triggered to shock the heart back into sinus rhythm. If the mechanical pulse rate tracks the electrical rate of depolarization, tachyarrythmia is confirmed. The diagnosis may be further confirmed by taking into account the rate at which the heart rate increases.
摘要翻译：一种用于在发生病理性心动过速或心室颤动的情况下进行心脏复律或除颤的心脏刺激器装置，其中将心脏去极化信号的速率与指示心动过速发作的预定心率值进行比较，同时，心脏的预放射期被监测以感测高于预定值的心率的增加是否伴随着预喷射周期的减少。如果没有，诊断病理学而不是生理发作，并启动心脏复律脉冲方案。通过监测心脏的机械脉冲，如果伴随低或非现有机械脉搏的心率过高，则诊断出心室颤动，并且触发心脏转复器将心脏震荡回窦性心律。如果机械脉搏率跟踪去极化的电速率，则确定速激速度。可以通过考虑心率增加的速率进一步确认诊断。

摘要： Change in the charge level of a storage capacitor of a defibrillator is accomplished by setting the charge control to the new level and successively closing and opening the charge switch. This actuates the safety relay so as to remove a low impedance shunt from the capacitor and it initiates the charging action. Charging ceases when the preset charge level is reached.
