摘要
A system and processor for tracking ectopic beats is disclosed wherein ECG data from multiple leads is acquired and a segment of said ECG signal is used as a reference template. The best fit between the reference template and the acquired data is determined using a correlation coefficient calculation. There is also disclosed a system and a processor for deriving a p-wave signal from a premature atrial contraction (PAC) beat in an ECG signal wherein ECG data is captured and processed so as to derive the p-wave signal from the PAC beat, thereby obtaining information on the p-wave in an ECG signal wherein the complexes partly overlap and obscure parts of the waveform.
