How can Sudden Cardiac Arrest be prevented?

Living a healthy lifestyle—exercising regularly, eating healthy foods, maintaining a healthy weight, and avoiding smoking—can help prevent SCA. Monitoring and controlling blood pressure, cholesterol levels and diabetes is also important. If there is a family history of SCA, it is important to be checked by a cardiologist or electrocardiologist. If abnormal heart rhythms (arrhythmias) are detected, they can be treated through implantable cardioverter defibrillator (ICD) therapy, use of medications such as ACE inhibitors, beta blockers and calcium channel blockers, and catheter ablation. Some patients, especially those who have had previous heart attacks, may benefit from the use of wearable cardioverter defibrillators (WCDs).
