Benjamin Pless, Phillip L Ball: Method for cardiac defibrillation. Ventritex, Gerstman & Ellis, August 21, 1990: US04949719 (128 worldwide citation)

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 whethe ...
