A risk factor is something that increases your likelihood of getting a disease or condition.
It is possible to develop arrhythmias with or without the risk factors listed below. However, the more risk factors you have, the greater your likelihood of developing arrhythmias. If you have a number of risk factors, ask your doctor what you can do to reduce your risk.
Risk factors for arrhythmias include:
The following medical conditions increase your chances of developing an arrhythmia:
- Heart muscle damage after heart attack
- Coronary artery disease

- Cardiomyopathy
- Diabetes
