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： 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.
