DEVICE AND METHOD FOR PACEMAKING AGAINST FREQUENT PULSE IN SYSTEM FOR CONTROLL- ING ARRHYTHMIA OF BOTH CARDIAC VENTRICLES

摘要

PURPOSE: To enable a patient to keep the improved blood power state during the operation for anti-frequent pulse start and stop treatment by giving start and stop pulses to the atrium at each elapsed time of N-number of VA delay periods and start and stop pulses to the ventricle of the heart at each elapsed time of N-number of AV delay periods according to the values of the VA period and the AV period. CONSTITUTION: The existence of frequent pulse is detected, the frequent pulse cycle length is measured, the VA period value smaller than or equal to the frequent pulse cycle length is determined, the initial value of the AV delay time is determined, a pulse is supplied to the venticule of the heart, a pulse is supplied to the atrium at the elapsed time of the determined AV period value, a pulse is supplied to the venticule at the elapsed time of the AV period value, and the supply of pulses to the atrium and the venticule is repeated until N-number of VA periods and N-number of AV period elapse to complete a first pulse string. M-number of a series of pulse strings similar to the first pulse string, and before the completion of the M-number of pulse trings, at least once the AV delay period value is changed from the programmed initial value.
