What is the life expectancy of person with pacemaker due to heart block?

Life with pacemaker: Pacers simply replace the electrical system in the heart but do not shorten life expectancy. Other heart issues like significant coronary/valve disease or congestive heart failure are the main heart issues that affect life expectancy. If placed for slow heart rates (sick sinus syndrome) or heart block then no specific reduction in life expectancy is noted.

It Varies: If heart block is the only cardiac issue, a pacemaker should fully correct this and cause no shortening of a person's life expectancy.
