Pacemakers are electronic devices that stimulate the heart with electrical impulses to maintain or restore a normal heartbeat. An implantable cardioverter-defibrillator (ICD) is an electronic device that tracks the heart rate and restores a normal rhythm, if required. The average life expectancy today for people with Down’s Syndrome is 50 to 60 years old, compared to an average of nine years in around 1900. 1 report their observations on the value of the “stand-up” test in the diagnosis of long QT syndrome (LQTS) and its usefulness in guiding patient management.
