What is it?

Changes in heartbeat may either be minor and asymptomatic or major and require medical treatment. Smoking, drinking alcohol, caffeine, stimulants, and some other medicines may cause an increased heart rate. Feeling stressed, or feeling pain, having fever, being pregnant, and exercising may also cause changes in heartbeat. Athletes may experience occasional pauses in normal rhythm. If the person does not experience any symptoms, and there is no family history of heart problems, further evaluation is not needed.

Signs & symptoms

Symptoms of arrhythmias include palpitations, dizziness, fainting, and shortness of breath, although having these symptoms does not always specific to heart rhythm problems.


The most effective way to diagnose an arrhythmia is with an electrical recording of heart rhythm called an ECG. If the ECG doesn't find a problem, further monitoring of the heart might be needed.


How arrhythmia will be treated will depend on whether it is a fast or slow arrhythmia or heart block.
