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.
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 ...
A slow heart rate isn't always a concern. For example, a resting heart rate between 40 and 60 beats a minute is quite common during sleep and in some people, particularly healthy young adults and trained athletes. If bradycardia is severe, an implanted pacemaker may be needed to help the heart maintain an appropriate rate.
A left ventricle (LV) ejection fraction of about 50% to 70% is categorized as normal. A mildly reduced LV ejection fraction is usually between 41% and 49%. A reduced LV ejection fraction is usually 40% or less. Even if you have a normal ejection fraction, your overall heart function may not be healthy.
Slowing a fast heart rate. A fast heart rate may correct itself. But sometimes medicine or other treatments are needed to slow down the heartbeat. Ways to slow a fast heart rate include: Vagal maneuvers. Simple but specific actions such as coughing, bearing down as if passing stool or putting an ice pack on the face can help slow down the heart ...

He or she may ask you questions about your symptoms and medical history. Your health care provider may recommend tests to check your heart rate and see if you have a heart problem that can cause bradycardia.
Pregnancy makes the heart and blood vessels work harder. During pregnancy, blood volume increases by 30% to 50% to nourish the growing baby. The heart also pumps more blood each minute, and the heart rate increases. Labor and delivery add to the heart's workload too. During labor, there are sudden changes in blood flow and blood pressure ...
This blood pressure chart can help you figure out if your blood pressure is at a healthy level. It also can help you understand if you need to take some steps to improve your numbers. Blood pressure is measured in millimeters of mercury (mm Hg). A blood pressure reading has two numbers. Top number, called systolic pressure.
In general, heart arrhythmias are grouped by the speed of the heart rate. For example: Tachycardia (tak-ih-KAHR-dee-uh) is a fast heartbeat. The heart rate is greater than 100 beats a minute. Bradycardia (brad-e-KAHR-dee-uh) is a slow heartbeat. The heart rate is less than 60 beats a minute. Fast heartbeat, called tachycardia
Supraventricular tachycardia (SVT) is a type of irregular heartbeat, also called an arrhythmia. It's a very fast or erratic heartbeat that affects the heart's upper chambers. SVT also is called paroxysmal supraventricular tachycardia. The typical heart beats about 60 to 100 times a minute.
