Oct 8, 2022 · A normal resting heart rate for adults ranges from 60 to 100 beats per minute. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness. For example, a well-trained athlete might have a normal resting heart rate closer to 40 beats per minute. To measure your heart rate, simply check your pulse.
Oct 13, 2023 · A heart arrhythmia may feel like a fluttering, pounding or racing heartbeat. Some heart arrhythmias are harmless. Others may cause life-threatening symptoms. 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.
Dec 15, 2023 · In a healthy heart, this signaling process usually goes smoothly. The resting heart rate is typically 60 to 100 beats a minute. But in tachycardia, something causes the heart to beat faster than 100 beats a minute. Risk factors. In general, things that may raise the risk of irregular heart rhythms that commonly cause tachycardia include ...
Mar 11, 2022 · Often the cause of heart palpitations can't be found. Common causes include: Strong emotional responses, such as stress, anxiety or panic attacks. Depression. Strenuous exercise. Stimulants, including caffeine, nicotine, cocaine, amphetamines, and cold and cough medications that contain pseudoephedrine. Fever.
May 7, 2022 · Diagnosis. To diagnose bradycardia, a health care provider will usually perform a physical exam and listen to your heart with a stethoscope.

Mar 8, 2024 · During atrial fibrillation, the heart's upper chambers — called the atria — beat chaotically and irregularly. They beat out of sync with the lower heart chambers, called the ventricles. For many people, AFib may have no symptoms. But AFib may cause a fast, pounding heartbeat, shortness of breath or light-headedness.
Mar 7, 2024 · In a healthy heart, this heart signaling process usually goes smoothly. The heart usually beats about 60 to 100 times a minute at rest. But in SVT, the heart beats faster than 100 beats a minute. The heart may beat 150 to 220 times a minute. Risk factors. Supraventricular tachycardia (SVT) is the most common type of arrhythmia in infants and ...
Mar 6, 2024 · In ventricular tachycardia, an irregular electrical impulse starting in the lower chambers of the heart makes the heart beat faster. Ventricular tachycardia is a type of irregular heartbeat, called an arrhythmia. It starts in the lower chambers of the heart, called the ventricles. This condition also may be called V-tach or VT.
Jul 8, 2023 · The heart's conduction system also is called the heart's electrical signaling system. Electrical signals start in a group of cells at the top of the heart called the sinus node. The signals tell the heart to beat. The sinus node also is called the heart's natural pacemaker. It can become weak as a person gets older.
Apr 30, 2022 · Premature ventricular contractions (PVCs) are extra heartbeats that begin in one of the heart's two lower pumping chambers (ventricles). These extra beats disrupt the regular heart rhythm, sometimes causing a sensation of a fluttering or a skipped beat in the chest. Premature ventricular contractions are a common type of irregular heartbeat ...
