Dynamically adjustable multiphasic defibrillator pulse system and method

A multiphasic pulse generator, comprising:

• at least a first subsystem that generates a first phase of a pulse, the first subsystem having a power source, an energy reservoir and a portion of an H-bridge circuit, wherein the first phase is one of a positive phase of the pulse and a negative phase of the pulse;
• at least a second subsystem that generates a second phase of the pulse, the second subsystem having a second power source, a second energy reservoir and a second portion of the H-bridge circuit so that a complete H-bridge circuit is formed between the at least first and second subsystems, wherein the second phase is an opposite polarity phase to the first phase;
• and
• a switching component that switches between the first and second subsystems to generate a therapeutic pulse having at least one positive phase and at least one negative phase.

A method for generating a therapeutic pulse, comprising:

• generating one or more positive phases for a pulse using a power source and an energy reservoir;
• generating one or more negative phases for a pulse using a second power source and a second energy reservoir;
• and
• switching between the one or more positive phases and the one or more negative phases to generate a therapeutic pulse having at least one positive phase and at least one negative phase.
