Yale New-Haven Hospital provides a full range of inpatient and outpatient arrhythmia management services. Facilities include two electrophysiology laboratories for device-based and interventional electrophysiology management, operating rooms for pacemaker and ICD implantation, and numerous clinics for outpatient evaluation.

Current Research
