Your pacemaker is designed to help your heart by keeping it beating in a normal rhythm. But, in rare cases, an implant can lead to a dangerous infection. Learn more.
Most implanted devices available today can go through a CT scan or an MRI scanner. However, older pacemakers can present a problem for radiologists. Learn more.

Our hearts rely on perfectly timed contractions to squeeze and refill an average of 100,000 times a day. When the electrical impulses driving this process are not uniform, certain areas of the main pumping chamber of the heart (left ventricle) may contract earlier than others. This reduces the heart’s ability to pump effectively, causing fatigue, … Read More
Just as a pilot’s plane needs maintenance for safety, the pilot himself needs regular checkups for his own health — especially when it comes to heart health. With the help of their cardiologists, many pilots can keep their hearts strong and continue to fly. Checking pilots’ health Federal Aviation Administration-authorized aviation medical examiners evaluate pilots … Read More
If your heart isn’t beating at the right rate or rhythm, doctors have several options to help you. Pacemakers and defibrillators take over pacing your heartbeat when heart disease and other conditions play havoc with heart rhythms. Your heart signals Normally, electrical impulses generated in your heart stimulate the heart to contract. This moves blood … Read More
Traditional pacemakers are implanted under the skin and attached to a wire that is inserted directly into the heart muscle. The device generates a current that travels down the wire to control the heart’s contractions. Complications related to pacemakers are generally related to these wires, known as leads, which can fracture or become infected. Removing … Read More
A unique pacemaker coupled with an implanted defibrillator benefits women with a specific kind of heart failure particularly well, according to new studies. However, it’s important to get the word out that women often don’t fit inside traditional treatment envelopes. Even though women do especially well with cardiac resynchronization therapy devices combined with an implanted defibrillator (CRT-D), … Read More
Sometimes the pathway in the heart’s electrical system is interrupted, which causes changes in heart rate and rhythm. A slow heartbeat can occur because the sinus node, the natural “battery” of the heart, is slow. Other times electrical conduction between the upper and lower chambers of the heart is disrupted. When this happens, the heart … Read More
