At the Cardiovascular Institute of San Diego in Chula Vista, cardiac electrophysiologist Steven K. Carlson, MD holds board certification in both cardiovascular disease and clinical cardiac electrophysiology from Suite 211 at 765 Medical Center Court. Acute arrhythmia presentations arriving at Sharp Chula Vista Medical Center Emergency Room route directly to the electrophysiology lab for evaluation and intervention. A University of Southern California medical degree preceded internal medicine training at UCLA Medical Center and cardiology fellowship back at USC, building subspecialty depth in ablation therapy and cardiac device implantation. The institute operates as a Scripps Affiliated Medical Group practice, and cardiovascular comorbidity screening extends to retinal vascular assessment in coordination with American Eye Associates and California Retina Associates. Advanced procedures include leadless pacemaker implantation, subcutaneous ICD placement, and radiofrequency catheter ablation for atrial fibrillation with 3D electroanatomical mapping.
