Pacemakers and ICDs

Martha Jefferson physicians and staff have specialized training and the advanced technology to perform the diagnostic and treatment procedures most needed by our community.


Pacemakers are used to treat cases of slow heart beats (bradycardia), heart failure. It is implanted beneath the skin and sends electrical impulses to the heart to help it pump properly. An electrode is placed next to the heart wall and small electrical charges travel through the wire to the heart.

Following implantation, pacemakers need to be periodically checked to ensure that they are functioning correctly. Some testing can actually be done over the phone, using a process called transtelephonic monitoring.

Martha Jefferson is a strong advocate for the use of MRI-compatible pacemakers. The MRI-compatible pacemaker minimizes the risk associated with high intensity magnetic fields, while continuing to help the heart beat at a more normal rate. For most patients in need of a pacemaker, Martha Jefferson works to offer this technology.

ICD (Internal Cardiac Defibrillator)

ICDs are used to evaluate cases of slow heart beats (bradycardia), fast heart beats (tachycardia), heart failure. A defibrillator is implanted beneath the skin, close to the heart.  It will sense dangerous heart rhythms and provide a lifesaving electrical charge to return your heart to a safe rhythm.

ICDs need to be periodically checked to ensure that they are functioning correctly.

Implantable Loop Recorder

Implantable Loop Recorders are used to evaluate recurring fainting. It is implanted under the skin, close to the heart. It has the ability to record the electrical activity of the heart, store irregular heart rhythms within set parameters and can be triggered to store events.
