Risk factors
By Mayo Clinic staffSick sinus syndrome can occur in people of all ages, even infants. Because it usually develops slowly, over many years, it's most common in people who are age 70 or older.
In rare cases, sick sinus syndrome may also be associated with certain conditions such as muscular dystrophy and other diseases which may affect the heart.
