I am a clinical engineer for an implantable device company and have years of experience with adult implants. However, I was just involved in a pacemaker implant in a 1 week old child with Sjorgens Syndrome. The patient had experienced 2nd and 3rd degree heart block at birth. In doing a web search for "sjorgens", most hits led me to sites for Lupus or connective tissue disease. What is Sjorgens Syndrome and what exact effect is it having on this childs heart? What might be the long term prognosis for the childs heart?
