hi here’s a list that may help you. many arrhythmias occur as a complication of a heart condition. for example ischaemic heart disease (which causes angina and heart attacks). this reduces the blood supply to parts of the heart which may include parts of the conducting system. a damaged section of heart muscle (following a heart attack) can trigger an arrhythmia or block electrical impulses. heart valve diseases can cause the heart muscle to enlarge which can trigger abnormal electrical activity. for example af is a common complication of mitral valve disease. high blood pressure can put strain on the heart and cause arrhythmias. age-related degeneration (ageing) around the conducting fibres is one cause of complete heart block. cardiomyopathy (a disorder of the heart muscle) can sometimes cause arrhythmias. some arrhythmias are due to abnormalities in the electrical pathways which are present from birth. one example is an extra electrical pathway which sometimes develops between the atria and ventricles. this can cause a type of svt. (however symptoms may not first start until you are a young adult. ) some congenital heart defects are associated with certain arrhythmias. inflammation of the heart and other less common heart disorders are other possible causes. your should find out that sex is not the bad fro what your asking a good orgasm does release some good things around our body’s as for exercise as long as its not to herd or fast you should be ok swimming would be good for you its gentle and less stressful and also low impact. hope this helps you. good luck
