Abstract
Electrotherapy systems and methods for delivering an electrostimulation treatment program to a user while reducing the risk of inducing cardiac fibrillation. The systems and methods detect electrostimulation treatment program delivery characteristics, including a pulse intensity above a preset limit; a pulse duration above a preset limit; an inappropriately compensated pulse; a charge per pulse above a predetermined limit; a current improperly exiting from a stimulation channel; a current present outside of a pulse; an excitation pulse and a compensation pulse generated on different channels; an inter-pulse time less than a predetermined limit; and a time between an excitation and a compensation pulse greater than a predetermined limit. The limits are selected in relation to an objective of reducing the risk of inducing cardiac fibrillation.
