Is there an age limit for having an eecp?

Probably not. Patients have to meet the criteria (not just age criteria) of the eecp center and of the cardiologist referring patients for treatment. One center states that it has treated patients ages 30-95 years old.
EECP. This is a procedure tried hen more effective treatments aren't giving the patient relief. Not aware of it being used in kids, generally in adults, often advanced age.
