• In the monopolar mode, the active electrode either touches the tissue directly or is held a few millimeters above

• As long as the heart tissue contracts concurrently it works as an effective blood pump. But when this concurrency cease to exist some problems begin to emerge. • One of

• And recently , complications and problems faced with the need of a surgical pocket for implantation of the device and the application of lead systems forced scientist

• Implantable stimulation systems use an encapsulated pulse generator that is surgically implanted and has subcutaneous leads that terminate at electrodes on or near the desired

This catheter provides a single pace/sense electrode which is used in conjunction with the right ventricular high-voltage defibrillation electrode for
