First Claim
1. A system for wireless generation of at least one standard ECG lead, comprisinga plurality of electrodes for application to a subject at separate points thereof;
- a remote receiver station for generating at least one standard ECG lead from signals detected by a first group of said plurality of electrodes,wherein said 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 said plurality of electrodes substantially simultaneously with the signal detection by said first group of said plurality of electrodes, said second group of said plurality of electrodes comprising at least one subset having at least three closely located electrodes arranged non-linearly for detecting two local bipolar signals;
a processor in said remote receiver station for calculation of a transform synthesizing each generated standard ECG lead from at least two of said non-standard ECG signals;
a disconnection unit for disconnection of said first group of electrodes from said subject following said calculation, said processor thereafter synthesizing said standard ECG lead from said non-standard ECG signals solely using said transform; and
a transfer unit for wireless transferring of said non-standard ECG signals to said remote receiver station (200) following said disconnection of said first group of electrodes,whereby said at least one standard ECG lead is wireless generated by said synthesizing following the disconnection of said first group of electrodes.
