Cardiac Pacemaker

An implantable medical device that delivers electrical impulses to regulate abnormal heart rhythms and maintain adequate cardiac output.

Key Facts

Consists of a pulse generator and pacing leads that monitor and stimulate the heart.
Often repurposed from human devices past their shelf-life to reduce veterinary costs.
Implanted via the jugular vein or diaphragm, with the generator placed under the skin.
Requires periodic non-invasive adjustments by a cardiologist to optimize battery life and stimulation strength.

The device directly addresses dangerously slow heart rates by providing consistent electrical stimulation.

Pacemakers are the primary treatment for electrical conduction failures like heart block.

Pacemaker implantation is the standard therapy to correct the erratic signaling of sick sinus syndrome.

Correcting the underlying rhythm with a pacemaker typically eliminates fainting episodes.
