As a board certified practitioner in Internal Medicine, Cardiovascular Diseases and Clinical Cardiac Electrophysiology, I currently practice at Mercy Hospital, Mason City, Iowa and the Covenant Clinic in Waterloo, Iowa. I am a Professor Emeritus at the University of Iowa since 2012 and, prior to that time, was a tenured Professor of Medicine at the University of Iowa and Iowa City, Iowa. I have directed the Clinical Cardiac Electrophysiology Programs and Clinical Cardiac Electrophysiology Fellowship training programs at the University of Iowa, Iowa City, Iowa and at Loyola University Medical Center, Maywood, Illinois. During my career, I have been involved in animal and human research, have been a member of the IRB and the IACUC, have been a member of multiple study sections at the NIH and have written hundreds of peer-reviewed manuscripts, chapters and a few books as well as electronic transmissions and numerous abstracts. The focus of my career has been clinical cardiac electrophysiology and includes management of patients who have arrhythmias and have risk for life-threatening consequences. I take care of patients who are candidates for pacemakers, implantable defibrillators and cardiac resynchronization therapy devices, who are candidates for catheter ablation and are candidates for various types of arrhythmia management. I have expertise in the areas of anticoagulation, autonomic perturbations, sudden cardiac death, ablation, device implantation, management of syncope, management of the athlete with arrhythmias, and caring for patients with atrial fibrillation, ventricular arrhythmias including PVCs, antiarrhythmic drug therapy and management of specific conditions such as postural orthostatic tachycardia syndrome an inappropriate sinus tachycardia. One area of focus includes cardiac electrical implantable device issues and another involves atrial fibrillation. Over the past several years, I have had the opportunity to become involved with a Department of Justice investigation regarding implantable defibrillators as an independent reviewer. I have served on guidelines and consensus document committees and have crafted such documents regarding athletes (The Bethesda Conference), supraventricular tachycardia (ACC/AHA Guidelines in process), syncope (ACC/AHA guidelines in progress), syncope units (European Society of Cardiology), syncope (European Society of Cardiology), dysautonomic syndromes (Heart Rhythm Society) and type of pacemaker implant (Heart Rhythm Society) and amiodarone (Heart Rhythm) and other similar documents. I have sat on multiple DSMBs and have chaired such committees. I am on multiple editorial boards and have reviewed for over 30 journals.
