Causes of Arrhythmia
What Causes Arrhythmia?
The direct cause of an abnormal heart rhythm is a breakdown in the heart’s electrical system. This breakdown can be caused by a number of conditions, including:
- Heart disease, including coronary artery disease
- Certain other diseases, including thyroid disease and anemia
- High blood pressure
- Fever or infection
- Physical or emotional stress
- Genetics (family history)
Arrhythmia can also be brought on by a host of substances, especially stimulants, including:
- Caffeine
- Tobacco
- Alcohol
- Cocaine
- Amphetamines
- Certain prescription and over-the-counter medications, including diet pills
- Certain foods and herbs
Sometimes, however, the cause of an abnormal heart rhythm cannot be accurately determined.
