Wireless Pacemakers: Rhythm Without Blues

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

Abnormally Rapid Heartbeats May Be Present at Birth (Video)

The heart’s electrical system conducts electrical impulses between the upper and lower chamber to keep the heart beating regularly and pump blood through our bodies. However, as with any electrical system, sometimes things don’t work exactly as they should. Occasionally a pathway that isn’t normally there is formed, which basically creates an electrical “short circuit” … Read More

The Ins and Outs of Irregular Heartbeats (Video)

The atria, the heart’s upper chambers, and ventricles, the heart’s lower chambers, work together to pump blood through the heart by alternately contracting and relaxing. The heart’s electrical system is the power source that makes this possible, and its natural pacemaker regulates normal rhythms. When your heart is beating normally, you usually don’t notice it. … Read More

The Ups and Downs of Your Heart Rhythms (Video)

Your heartbeat is triggered by electrical impulses that travel down a special pathway through your heart. At rest, most people’s hearts beat about 50 to 70 times each minute. That rate slows at what’s referred to as peaceful rest. When you exercise, your body needs more oxygen-rich blood, and your heart rate increases to compensate. … Read More

Learning Curves

Life’s learning curves are steep these days for Jason Lappe, MD, a Cleveland Clinic fellow. There’s his brand-new daughter, Emma, who was born this month.
