The main types of arrhythmia are bradyarrhythmias; premature, or extra, beats; supraventricular arrhythmias; and ventricular arrhythmias.

Your doctor will decide on a treatment approach based on the type of angina you have, your symptoms, test results, and risk of complications. Unstable angina is a medical emergency that requires immediate treatment in a hospital. If your angina is stable and your symptoms are not getting worse, you may be able to control your angina with heart-healthy lifestyle changes and medicines. If lifestyle changes and medicines cannot control your angina, you may need a medical procedure to improve blood flow and relieve your angina.

You may have an increased risk for angina because of your age, environment or occupation, family history and genetics, lifestyle, other medical conditions, race, or sex.
