Dr. Bunch specializes in the diagnosis and management of heart rhythm disorders. He performs a broad range of procedures including endocardial and epicardial catheter ablation, insertion of implantable loop recorders, pacemakers (leadless and traditional), implantable cardioverter defibrillators (ICDs – subcutaneous and traditional), and biventricular ICDs and pacemakers. He has extensive ablation experience in treatment of abnormal heart rhythms including supraventricular tachycardia, atrial fibrillation, WPW (Wolff-Parkinson-White syndrome), ventricular tachycardia, ventricular fibrillation, and premature ventricular contractions.

Dr. Bunch is interested in the management of atrial and ventricular arrhythmias, in particular nonpharmacologic strategies such as catheter ablation and in enhancing the safety of both pharmacologic and nonpharmacologic treatments. His current research involves defining mechanisms underlying the association of atrial fibrillation and dementia and looking at therapeutic opportunities to lower risk of cognitive decline, the integration of wearable and implantable devices to improve early diagnosis and treatment of arrhythmias, and in improving mapping and catheter ablation of arrhythmias.
