Clinical Interest for Patients
My clinical expertise encompasses all aspects of arrhythmia treatment and include the use of anti-arrhythmic medication, catheter ablation, and implantable devices for cardiac rhythm management. I am especially interested in challenging cases with difficult to treat arrhythmias that may be refractory to anti-arrhythmic drugs and prior ablation attempts. Specific conditions treated and procedures performed include: •Atrial Fibrillation (AF or A fib) •Supraventricular Tachycardia (SVT) •Wolff-Parkinson-White Syndrome (WPW) •Ventricular Tachycardia (VT) •Ventricular Fibrillation (VF) •Premature Ventricular Contractions (PVCs) •Implantable Cardioverter-Defibrillator (ICD) Implantation and Management •Pacemaker and Cardiac Resynchronization Therapy (CRT) Implantation and Management •Syncope (Fainting) •Palpitations (Rapid or Irregular Heart Beat)

Care Philosophy
I believe that a high level of patient education regarding the diagnostic and therapeutic strategies available is critical to alleviating the anxiety caused by cardiac arrhythmias. Part of this process involves direct communication with patients and their family. With this clear communication in mind, I believe that I can work with patients effectively to successfully treat any arrhythmia.

Personal Interests
I enjoy going on family adventures with my wife and 2 children, hiking, bicycling, and skiing.

Volunteer Activities
I participate in community programs promoting education and training for cardiac resuscitation and sudden death prevention.

Clinical Interests for Referring Providers
My clinical expertise encompasses all aspects of arrhythmia treatment and include the use of anti-arrhythmic medication, catheter ablation, and implantable devices for cardiac rhythm management. I am especially interested in challenging cases with difficult to treat arrhythmias that may be refractory to anti-arrhythmic drugs and prior ablation attempts. We have all equipment necessary for arrhythmia management, including 3D electroanatomical mapping, radiofrequency and cryoablation technology, intracardiac ultrasound, cardiac MRI, and laser lead extraction sheaths. If you would like to speak with me regarding a patient, please contact me through the clinic at 720-848-6510 or the hospital operator at 720-848-0000 after hours. Urgent hospital transfers can be arranged through the hospital transfer center at 720-848-2828.

Research Interest for Referring Providers
I have received training and gained experience in a wide array of research methods including those used in molecular genetics, observational clinical research, clinical trials, outcomes assessment, and engineering/biophysics experimentation. Since my specialization in cardiology and cardiac electrophysiology, I have focused my research and scholarship on the diagnosis and treatment of cardiac arrhythmias. Under this overarching theme, I have identified 3 broad and overlapping areas where I have initiated projects with a goal of generating new knowledge and technology as a contribution to science and education in the field of cardiovascular medicine. 1) Diagnosis of Cardiac Arrhythmias and Identification of Patients Responsive to Treatment. I have written several manuscripts and case reports describing techniques used in the clinic or electrophysiology laboratory for diagnosing cardiac arrhythmias in order to guide therapy. These projects include the identification and characterization of certain high-risk populations such as those with certain genetic polymorphisms, cardiac sarcoidosis, hypertrophic cardiomyopathy, and congenital heart disease. I have specifically focused on cardiac sarcoidosis as a rare and under-recognized arrhythmogenic disorder and have developed or established of several collaborative projects characterizing this disease. 2) Clinical Assessment of Catheter Ablation as a Treatment for Cardiac Arrhythmias. As an extension of my clinical expertise and interest in catheter ablation, I have collected and analyzed data for the purpose of evaluating and improving the safety and efficacy of this procedure. Projects include evaluating the use of ICD technology and stored electrograms for guiding ablation of ventricular arrhythmias as well as observational research on procedural outcomes. 3) Development of New Technologies for Cardiac Ablation. I am interested in the application of biophysical and engineering principles used in the cardiac electrophysiology laboratory to improve cardiac ablation. I have established the University of Colorado Ablation Biophysics Laboratory (2013) and the Anschutz Medical Campus Large Animal Cardiovascular Catheterization Laboratory (2015) where we are evaluating established and experimental ablation technologies. A number of innovative therapeutic advances are presently in development in this laboratory including strategies to enhance or facilitate energy delivery to improve ablation efficacy and safety.
