Abstract
A system includes a pulse generator including a can electrode and a lead couplable to the pulse generator, the lead including a distal coil electrode and a proximal coil electrode, wherein both of the coil electrodes are electrically uncoupled from the can electrode such that a unipolar sensing vector is provided between at least one of the coil electrodes and the can electrode.

A system comprising:
- a pulse generator including a can electrode;
- and
- a lead couplable to the pulse generator, the lead including a distal coil electrode and a proximal coil electrode, wherein both of the coil electrodes are electrically uncoupled from the can electrode such that a unipolar sensing vector is provided between at least one of the coil electrodes and the can electrode.
A system comprising:
- a pulse generator including a can electrode;
- and
- a lead couplable to the pulse generator, the lead including a distal coil electrode and a proximal coil electrode, and further including a tip pacing/sensing electrode and a ring electrode, wherein the proximal coil electrode and the distal coil electrode are electrically uncoupled from the can electrode such that a unipolar sensing vector is provided between the distal electrode and the can electrode.
An apparatus comprising:
- a pulse generator including a housing can electrode;
- electronics located within the pulse generator;
- and
- an electrical connection between the housing can electrode and the electronics;
- wherein the electronics and electrical connection are configured such that when a lead is coupled to the pulse generator, a distal coil electrode on the lead is electrically uncoupled from the housing can electrode by the electrical pathway and a proximal coil electrode on the lead is electrically uncoupled from the housing can electrode, such that a unipolar sensing vector is provided between at least one of the coil electrodes and the can electrode.
