Interferential cardiac preconditioning and depolarization

摘要

Exemplary systems, devices, and methods pertaining to cardiac related therapy and particularly to interferential cardiac preconditioning and depolarization are described. A cardiac arrhythmia is detected from electrogram data sensed from a patient's heart and a region of the heart affected by the cardiac arrhythmia is determined. The affected region is interferentially energized by multiple cycles of two concurrently delivered alternating currents which are offset in frequency.
