Hi, may I answer your health queries right now ?  Please type your query here...My Father-in-law survived a heart attack 4 years ago and was saved by CPR.  He then had a pacemaker put in and has gone off three times over the years but generally is in good health.  What is the average lifespan after CPR?  Thanks
Welcome and thank you for asking on Chat Doctor! I have gone through you question carefully. Survival after CPR depends on on the underlying heart disease and the severity of heart dysfunction and comorbidities (Diabetes, Hypertension etc.), level of physical activity status. If frequent CPR s are being required survival is usually poor. Hope you will find this answer helpful! Wishing all the best,
