Medical system for detecting heart events including an electrode lead provided with a multi-dot electrode unit that comprises at least three dot electrodes, said multi-dot electrode unit is adapted to be used for intra-corporal sensing of heart signals. The heart signals sensed by each of the dot electrodes am applied to a processing means where the signals are combined and a synthetic reference signal is determined. The differences between each dot electrode heart signal and the synthetic reference voltage are determined, and an indication signal is formed based upon said differences, wherein said indication signal is used to detect heart events. |
