    摘要： A cardiac therapy method with duration timer is disclosed, using an implanted cardiac pulse generator. A patient's heartbeat is sensed and the intervals between heartbeats are averaged. The number of temporary storage bins, in the form of RAM locations, are provided, including a sinus bin, a low rate tachycardia bin, a high rate tachycardia bin, and a fibrillation bin. The storage bin corresponding to the cardiac rhythm band of the determined average heartbeat interval is incremented. A maximum count limit is assigned to each storage bin. When the first bin reaches its maximum count limit, a diagnosis of the patient's cardiac rhythm is provided. Upon detection of a tachycardia, a duration timer is started and the tachycardia is treated in accordance with a programmed routine. If sinus is detected during the predetermined time period, then the duration timer is cleared. If fibrillation is detected during the predetermined time period, then the duration timer is cleared and fibrillation is treated by delivering a high energy shock to the heart.

    摘要翻译： 公开了一种使用持续时间计时器的心脏治疗方法，其使用植入式心脏脉冲发生器。 感测患者的心跳，心跳间的间隔平均。 提供以RAM位置形式的临时存储箱的数量，包括窦仓，低速率心动过速仓，高速率心动过速仓和原纤维仓。 对应于确定的平均心跳间隔的心律带的存储箱增加。 每个存储仓分配最大计数限制。 当第一个箱体达到其最大计数极限时，提供对患者心律的诊断。 在检测到心动过速时，开始持续时间计时器，并根据程序程序对心动过速进行治疗。 如果在预定时间段期间检测到窦，则清除持续时间定时器。 如果在预定时间段期间检测到原纤维化，则清除持续时间定时器，并通过向心脏递送高能量冲击来治疗原纤维颤动。

    摘要： A method for cardiac defibrillation is described, for use with an implanted defibrillator. A patient's R-waves are sensed to detect the R-R intervals. If an arrhythmia is detected, the charging of a capacitor is commenced. Determination are made whether the arrhythmia is still in progress and whether the capacitor is charged a predetermined amount. If the arrhythmia is not still in progress, the charging is discontinued. If the arrhythmia is still in progress and the capacitors are charged a predetermined amount, another R-R interval is detected and if the R-R interval is shorter than a selected amount, a shock is delivered to the heart.
