Arrhythmias are abnormal or irregular heartbeats. They occur when the electrical impulses in your heart coordinate the natural rhythm incorrectly.
Most people have experienced an arrhythmia. However, you may have had an arrhythmia without any symptoms. Your doctor may be the first to notice signs of an arrhythmia. This will probably be during a routine physical exam when they listen to your heartbeat or perform an electrocardiogram (ECG).
Symptoms of arrhythmias are varied and can indicate either a harmless condition or one that needs immediate attention. To be safe, you should consult your doctor if you have any of these symptoms.
The most common signs and symptoms of arrhythmias include:

The main symptom of this arrhythmia is a slow heartbeat. The body relies on consistent blood flow, so a slow heartbeat can be a serious problem. If the brain doesn’t get enough blood, it may lead to unconsciousness. A slow heart rate may not be a problem for people who are fit. But in others, it can cause a serious condition like a heart attack, chemical imbalance, or an underactive thyroid gland.
