About the Symptom
Irregular pulse indicates that the heart is out of its usual rhythm. It may feel like the heart skipped a beat, added a beat, or is "fluttering."

A rapid heart rate prior to fainting with loss of consciousness
Peripheral cyanosis

Fainting with loss of consciousness
Possible Causes
Generally, Irregular heartbeat can be related to:
- Atrial Fibrillation (AF)
Atrial fibrillation is a heart condition causing an irregular and often abnormally fast heart rate, which can result in blood clots in the heart. It increases the risk of stroke, heart failure, and other heart-related complications. Common causes include heart valve diseases and heart failure.
- Pulmonary Arterial Hypertension
Pulmonary arterial hypertension is high blood pressure in the small blood vessels of the lungs. It can be caused by heart disease, connective tissue disease, blood vessel disease, high blood pressure, liver disease, blood clots in the blood vessels to the lungs, and lung diseases. It can affect anyone but is more common in women.
- Long QT Syndrome
QT prolongation syndrome is a heart signaling disorder that can cause fast, chaotic heartbeats (arrhythmias). It can be present from birth or develop later in life due to certain medical conditions, specific drugs, or mineral imbalances.
- Benign Arrhythmias (Palpitations)
- Familial Amyloid Polyneuropathy
- Graves' Disease
Cardiac Amyloidosis
- Amyloidosis
Fabry Disease / Lysosomal Storage Disorder
Related serious diseases
Sometimes, Irregular heartbeat may be related to these serious diseases:
- Sick Sinus Syndrome, Complete AV Block
These conditions involve issues with the heart's electrical conduction system. Signals may be transmitted too fast, too slow, or not at all to some areas of the heart. Both men and women are affected, and the risk increases with age.
