A new generation of miniaturized pacemakers can speed up slow hearts without the wires that may break or become infected.
When all circuits are firing properly, your heart’s electrical system spreads electrical impulses seamlessly through the heart. However, sometimes an abnormality occurs that creates a block in the system. Learn how and why heart block occurs.
Your heart has its own electrical system, and like any electrical system, sometimes issues occur with the “wiring.” When this happens — usually due to a condition someone is born with — the result is an abnormally rapid heartbeat.
Atrial fibrillation, also called AFib, is the most common irregular heart rhythm. Our heart is powered by a complex electrical system, and sometimes it misfires – which causes a fast, chaotic rhythm that can be alarming. Learn more.
People who experience a certain type of abnormal heart rhythm sometimes can see their beats per minute rise from a normal of 70 to up to 250. This occurs when there are issues with the “bridge” that connects the heart’s “circuits.”
Your heart has its own “electrical system,” which powers the beating of your heart. The heart’s natural pacemaker regulates your heart’s rhythm, unless something irregular — called an arrhythmia — occurs.
You’ve surely noticed how your heart rate increases when you exercise and slows down at rest—but most of us don’t think about how or why this happens. The answers may surprise you.
