Approximately 1 million individuals in the United States are at high risk for sudden cardiac death. Sudden cardiac death is often associated with ventricular fibrillation (VF), so patients at high risk for VF are fitted with an implantable cardioverter (ICD). ICDs rapidly detect and treat abnormal rhythms. Unfortunately, while ICDs can save lives, they also reduce patients’ quality of life and psychological state.

The proposed technology delivers low energy unique pacing for pain-free defibrillation. By reducing the defibrillation energy, the system reduces heart damage and eliminates the pain and anxiety associated with defibrillation shocks. In addition, the technology can be easily incorporated into current ICDs.
