Bradycardia (brad-e-KAHR-dee-uh) is a slow heart rate. The hearts of adults at rest usually beat between 60 and 100 times a minute. If you have bradycardia, your heart beats fewer than 60 times a minute. Bradycardia can be a serious problem if the heart rate is very slow and the heart can't pump enough oxygen-rich blood to the body.
For bradycardia, basic questions to ask your health care provider include: What is likely causing my slow heart rate? What tests do I need? What's the most appropriate treatment? What are the possible complications? How will my heart be monitored? How often will I need follow-up appointments?
Slow heartbeat, called bradycardia. A heart rate below 60 beats a minute is considered bradycardia. But a low resting heart rate doesn't always mean there's a problem. If you're physically fit, your heart may be able to pump enough blood to the body with less than 60 beats a minute.
Tachycardia may not cause any symptoms or complications. But sometimes it's a warning of a medical condition that needs attention. Some forms of tachycardia can lead to serious health problems if left untreated. Such problems may include heart failure, stroke or sudden cardiac death.
Tachycardia-bradycardia syndrome. The heart rate alternates between unusually slow and fast rhythms, often with a long pause between heartbeats.
Problems with the heart's structure are the most common cause of atrial fibrillation (AFib). Heart diseases and health problems that can cause AFib include: A heart problem you're born with, called a congenital heart defect. A problem with the heart's natural pacemaker, called sick sinus syndrome.
A pacemaker is a small, battery-powered device that prevents the heart from beating too slowly. You need surgery to get a pacemaker. The device is placed under the skin near the collarbone. A pacemaker also is called a cardiac pacing device. There are different types of pacemakers. Single chamber pacemaker.
Make sure you know how you react to the medicine before you drive, use machines, or do other things that could be dangerous if you are dizzy or not alert. If you feel dizzy, lie down so you do not faint. Then sit for a few moments before standing to prevent the dizziness from returning.
Ventricular tachycardia is caused by faulty heart signaling that makes the heart beat too fast in the lower heart chambers. The lower heart chambers are called the ventricles. The fast heart rate doesn't allow the ventricles to fill and squeeze to pump enough blood to the body.
Lowering blood pressure may reduce the risk of strokes and heart attacks. Losartan is an angiotensin II receptor blocker (ARB). It works by blocking a substance in the body that causes blood vessels to tighten. As a result, losartan relaxes the blood vessels.
