Cardiac arrhythmias that result from coronary artery disease can be prevented by taking the following actions to modify your risk factors:

  • Eat a heart healthy diet, including eating an abundance of vegetables and fruits, fish, and plant sources for protein and avoiding saturated and trans fats.

  • Control your cholesterol and high blood pressure.

  • Quit smoking.

  • Control your weight.

  • Get regular exercise.

Cardiac arrhythmias related to medications can be minimized by checking with a health care professional or pharmacist about any potential drug interactions. You might have to switch to another medication or reduce the dose of a problem medication. Ventricular fibrillation resulting from electrical shock can be prevented by following routine safety precautions around live wires and by seeking shelter during electrical storms.

Not all cardiac arrhythmias can be prevented.
