PACEMAKER IMPLANTATION

 








Why is a pacemaker implanted?


Pacemaker implantation may be done for different reasons. Any damage to the heart muscle, or the electrical conduction system, will interfere with the ability of the heart to function normally.This may be an indication for a pacemaker. Sick sinus syndrome (though rare) or myocardial infarction are examples.


What are some symptoms of a dysfunctionl natural pacemaker?

Patients who have dysfunction of their own natural pacemaker may experience dizziness, syncopal episodes (temporary loss of consciousness), chest pain, shortness of breath, fatigue, and a decrease in  blood pressure (hypotension).Learn more: Sessions 18

Why do these symptoms occur?
These symptoms are due to a lack of blood flow to the body's organs.

Notes for Nurses:
- See the sample of an EKG above showing a pacemaker lead (wire) in the ventricle. There is normally a spike in front of the QRS. The spike may not appear if the pacemaker malfunctions.
- Spikes in front of P and QRS means both chambers are paced. Learn more about :
