摘要：

A method for analysin ECG signals is disclosed. The method includes sensing a time-varying intracardiac potential signal and finding a fit of the time-varying intracardiac potential signal to a predefined oscillating waveform (step 206). The predefined oscillating waveform comprises a first differential of a Gaussian function, which is skewed by an asymmetry factor. An annotation time of the signal may then be derived from the fitted signal, rather than from the raw signal (step 212).
