Multimode ICD system comprising phased array amplifiers to treat and manage CRT, CHF, and PVC disorders using ventricle level-shifting therapy to minimize VT/VF and SCA

An implantable cardioverter defibrillator (ICD) system for administering cardiac therapy to a patient, which comprises:

• a subcutaneous case capable of being positioned under a patient's skin and in communication with the patient's heart;
• an arbitrary waveform control system located within the subcutaneous case, the arbitrary waveform control system comprising:
• a microcontroller or FPGA having a memory;
• differentially driven phased array amplifiers comprising hot can amplifier A1 and amplifiers A2, A3, and A4;
• a wireless transmitter/receiver;
• and
• a battery;
• one or more sensors;
• a bipolar pacing lead to be positioned in a right ventricle (RV) of the patient's heart and in functional communication with amplifier A4;
• a right ventricular (RV) pacing and shocking coil/defibrillation lead in functional communication with amplifier A2;
• and
• a left ventricular (LV) and/or coronary sinus (CS) pacing lead in functional communication with amplifier A3,
• wherein the bipolar pacing lead, amplifier A4, the right ventricular (RV) pacing and shocking coil/defibrillation lead, amplifier A2, the left ventricular (LV) and/or coronary sinus (CS) pacing lead, and amplifier A3 form a triangular electrical field, and
• wherein, based upon sensor data and demand criteria software programmed into the memory of the microcontroller or FPGA, the bipolar pacing lead, the right ventricular pacing and shocking coil/defibrillation lead, and the left ventricular and/or coronary sinus pacing lead deliver cardiac therapy to the patient's heart.
