Signs and symptoms of arrhythmias

Symptoms of arrhythmias vary from person to person, and depend on the source of the abnormality. Some people with mild arrhythmias have no symptoms at all. If symptoms are experienced, these may include any of the following:

Palpitations (strong or “galloping” heartbeat)
Skipped heartbeat
Dizziness, fatigue or fainting (syncope) as a result of the brain not getting enough oxygen-rich blood. This could manifest as unexplained falls, particularly in elderly individuals.

Angina (chest pain, pressure or discomfort)
Shortness of breath (dyspnea)

In severe cases, it could also result in cardiac arrest and death.
