Abstract
A system for wireless generation of at least one standard ECG lead comprises a plurality of electrodes for application to a subject at separate points thereof and a remote receiver station for generating at least one standard ECG lead from signals detected by a first group of said plurality of electrodes. The system further comprises a wireless sensing unit for generating at least two non-standard ECG signals from bipolar signals detected by a second group of the plurality of electrodes, a processor in the remote receiver station for calculation of a transform synthesizing each generated standard ECG lead from at least two of the non-standard ECG signals, a disconnection unit for disconnection of the first group of electrodes from the subject following the calculation, and a transfer unit for wireless transferring of the non-standard ECG signals to the remote receiver station following the disconnection of the first group of electrodes.
