University Hospital has a dedicated state-of-the-art electrophysiology laboratory where permanent pacemakers and pacer cardioverter defibrillators are implanted. These devices serve to prevent bradydysrhythmias, prevent sudden cardiac death and improve congestive heart failure symptoms. Around 200 pacemaker and defibrillator implants were performed at MUHC in 2009. Additionally, University of Missouri Health Care cardiologists implant pacemakers and defibrillators in the cardiac catheterization laboratories at the Harry S Truman Veteran Affairs Medical Center (HSTVAMC). More than 85 pacemaker and defibrillator implants were performed at HSTVAMC in 2010.
