How can I increase my ejection fraction rate and I have an aicd with idiopathic restrictive cardiomyopathy?

Confused. Restrictive cardiomyopathy is not associated with a low ef. Perhaps you meant "idiopathic dilated cardiomyopathy"? Ef can be improved by using a combination of beta blockers (especially coreg), vasodilators (especially ace-inhibitors) and using a resynchronization icd if appropriate in your case. Avoiding alcohol is also mandatory.
