Method and system for the selection of cardiac defibrillation shocks based on discomfort
First Claim
1. A method of selecting a shock profile for a defibrillator based on patient discomfort to a plurality of different defibrillating shocks, comprising:
- delivering a first defibrillating shock having an associated first shock profile to a patient;
measuring the physical displacement of a first selected region in the patient associated with the first shock during the first delivering step;
delivering a second defibrillating shock having an associated second shock profile to the patient;
measuring the physical displacement of a second selected region in the patient associated with the second shock during the second delivering step, wherein the second selected region is the same as or different from the first selected region; and
selecting one of the first or second shock profiles based on which shock profile has the lesser amount of associated measured physical displacement.

Abstract
Methods, systems and computer program products for selecting a shock profile for a defibrillator based on patient discomfort to a plurality of different defibrillating shocks include delivering a first defibrillating shock having an associated first shock profile to a patient, and measuring the associated physical displacement of a selected region in the patient. A second defibrillating shock having an associated second shock profile is delivered to the patient, and the associated physical displacement of the selected region in measured. One of the first or second shock profiles is selected based on which shock profile has the lesser amount of measured physical displacement.

28. A defibrillator comprising:
-
an implantable housing; a power source held in the housing; a controller held in the housing operatively associated with the power source; shock generator held in the housing operatively associated with the power source and the controller, the shock generator being configured to deliver a plurality of different selectable shock profiles, each having a respective predetermined shock strength, waveform, and shock vector; computer readable program code operatively associated with the controller for determining body displacement to estimate patient discomfort during the delivery of selected defibrillating shock profiles; and computer readable program code operatively associated with the controller and the shock generator for selectively delivering a selected defibrillation shock profile that is associated with a reduced body displacement value for a particular patient to thereby reduce patient discomfort during use of the defibrillator in an individualized manner. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
