Abstract:
1. A method of synthesizing electrocardiographic (ECG) signals comprising receiving signals from a first group of electrodes connected to predetermined locations on a human body to acquire a first set of ECG signals and deriving at least one further ECG signal using predetermined transformation(s) on said first set of ECG signals or a subset thereof to form a desired set of signals, wherein the first group of electrodes comprises standard 12 lead electrode site V 5 , standard 12 lead electrode site V 2 replaced by an electrode position Vc, which is defined to be on the sternum directly between the standard electrode sites V 1 and V 2 , at least one electrode positioned substantially level with V 5 on the right anterior axillary line, and at least one further electrode positioned on each of the right hand side and left hand side of the body, wherein said ECG signals are synthesized from data obtained from less than ten electrode sites.
