Medically reviewed by Debra Sullivan, Ph. Symptoms Causes Risk factors Diagnosis Treatment Outlook Prevention An abnormal heart rhythm is when your heart beats too fast, too slow, or irregularly. The types of abnormal heart rhythms The most common types of abnormal heart rhythms are: Tachycardia Tachycardia means that your heart is beating too fast. There are three subtypes of tachycardia: Supraventricular tachycardia occurs in the upper chambers of your heart known as the atria. Ventricular tachycardia occurs in the lower chambers known as the ventricles.
With sinus tachycardia, your heartbeat returns to normal once you get better or become calm. Atrial fibrillation This disorganized heart rhythm occurs in the upper chambers of the heart. Atrial flutter An atrial flutter AFL typically occurs in the right atrium, which is one of the two upper chambers of the heart.
Ventricular fibrillation Ventricular fibrillation VF can stop the heart from beating and cause cardiac arrest. Premature contractions With most premature contractions, the heart appears to skip a beat when the pulse is taken in the wrist or chest. What are the symptoms of abnormal heart rhythms?

They recruited more than 29, people without any history or heart disease, high blood pressure , or any other type of cardiovascular disorder, and measured their resting heart rates when they started the study and again 10 years later.
This study was published in the Journal of the American Medical Association. Among the group whose heart rates stayed under 70 throughout the study, there were 8. Among those whose heart rates rose above 85, there were The results also suggested that lowering your resting heart rate over time may be beneficial, but the researchers could not say that for certain.
The best time to measure it is before you get out of bed in the morning. You can measure your heart rate at your wrist or neck by placing one or two fingers over a pulse point, counting the number of beats in 15 seconds, and multiplying by four.
Knowing yours can be an important heart-health gauge. As you age, changes in the rate and regularity of your pulse can change and may signify a heart condition or other condition that needs to be addressed. To get the most accurate reading, put your finger over your pulse and count the number of beats in 60 seconds. It could be the result of taking a drug such as a beta blocker. A lower heart rate is also common for people who get a lot of physical activity or are very athletic. Keeping tabs on your heart rate can help your doctor determine whether to change the dosage or switch to a different medication.
