A lead carrying three electrodes is introduced into a cardiac chamber. Two of the electrodes are connected to the output of a pulse generator and are disconnected from the pulse generator output during sensing. All three of the electrodes are connected to the input of a sensing amplifier during sensing and two of the electrodes are disconnected from the input during pacing. | |
