Abstract
A method of measuring a source impedance of at least one cardiac electrical signal in a mammalian heart is provided. A first amplifier system is operated. A first signal from a chamber of the heart is received. The first signal is passed through a first amplifier. A second amplifier system is then operated. A second signal from the chamber of the heart is received. The second signal is passed through a second amplifier. Finally, the source impedance of at least one cardiac electrical signal is calculated. The source impedance is based on the amplified first signal and the amplified second signal.
