If you or someone you love has AFib, learn more about what it is; why treatment can save lives; and what you can do to reach your goals, lower your risks and live a healthy life.A premature heartbeat may feel like your heart skipped a beat. These extra beats are generally not a concern. They rarely mean you have a more serious condition. Still, a premature beat can trigger a longer lasting arrhythmia, especially in people with heart disease. Occasionally, having very frequent premature ventricular beats may lead to a weak heart. Arrhythmia. National Heart, Lung, and Blood Institute. https://www.nhlbi.nih.gov/health-topics/arrhythmia. Accessed June 13, 2023. Tachycardia (tak-ih-KAHR-dee-uh) is a fast heartbeat. The heart rate is greater than 100 beats a minute. About 15% to 20% of people who have strokes have this heart arrhythmia. The clot risk is why patients with this condition are prescribed blood thinners*. Determined to show to the world of what he realized was the landscape 4th dimension, Smith spent over two decades piecing together the clues of this unseen grounds to create a remarkably beautiful hand-painted map.

Some people with atrial or supraventricular tachycardia may have no symptoms. Others may experience:Preventing atrial or SVT can be more difficult than treatment. But making the following lifestyle changes may help: The heart's electrical system controls the heartbeat. The heart's electrical signals start in a group of cells at the top of the heart called the sinus node. They pass through a pathway between the upper and lower heart chambers called the atrioventricular (AV) node. The movement of the signals causes the heart to squeeze and pump blood. The disruption results in a faster than normal heart rate. This rapid heartbeat keeps the heart’s chambers from filling completely between contractions, which may compromise blood flow to the rest of the body. Risk factors for Atrial or SVT Surgeryto implant a cardioverter defibrillator(ICD), which delivers an electrical pulse to the heart to reset a dangerously irregular heartbeat.

Atrial fibrillation is a quivering or irregular heartbeat, or arrhythmia. Atrial fibrillation, also known as AFib or AF, can lead to blood clots, stroke, heart failureand other heart-related complications. Over 12 million people are projected to have AFib by 2030.

Stimulants can cause the heart to beat faster and may lead to the development of more-serious arrhythmias. Illegal drugs, such as amphetamines and cocaine, may greatly affect the heart. Some may cause sudden death due to ventricular fibrillation. There are times when it is OK to have a fast or slow heartbeat. For example, the heart may beat faster with exercise or slow down during sleep. Born in London, the author attended boarding schools in Dorset.
