General Cardiology | Office-Based Diagnostics | Arrhythmia Specialists

Comprehensive heart rhythm care…

From AF Ablation to Pacemakers, we are arrhythmia specialists.

Embrace a future where heart rhythm disorders can be cured, rather than treated with lifelong medication. Don't allow anxiety over palpitation to dictate your life. Learn about our array of advanced electrophysiology services.


Tele-Medicine and remote medical services.

Digital medicine is bringing back the age of the physician house-call. Cardiac treatment for our patients isn’t limited by their ability to travel to the clinic. We offer consultation and follow-ups by Tele-Medicine. Other cardiac services can also be performed remotely, including pacemaker and ICD follow-up, and even monitoring of your home blood pressure by our office staff. Good medical follow-up doesn’t have to be inconvenient—it can now be done from the comfort of your own home. Ask about our Tele-Medicine services.


Affiliations with Major San Jose Area Hospitals

Our seamless collaboration with local area hospitals ensures your cardiac care is timely, coordinated, and of the highest standard. Local area hospitals we admit patients to include Good Samaritan Hospital and O’Connor Hospital. Minor surgical procedures may also be performed at local surgery centers for added convenience and accessibility.

Dr. Chow Cardiac Care

Dr. Chow provides comprehensive patient services in both general cardiology and electrophysiology (heart rhythm disorders).

General cardiology services include consultation and patient management, stress testing, echo, vascular ultrasound, ECG and heart rhythm monitoring, and more. Cardiac electrophysiology services include pacemaker and ICD implantation, electrophysiology studies, and catheter ablation–including atrial fibrillation ablation. Dr. Chow also provides services in his outpatient device management clinic, incorporating remote (at home) pacemaker and ICD follow-up.

Meet Dr. Chow

Welcome to the practice of Dr. Theodore Chow, a distinguished cardiologist and cardiac electrophysiologist with over 20 years of experience. A graduate of Princeton University and Johns Hopkins Medical School, with specialty training in cardiology and electrophysiology at Harvard Medical School, Dr. Chow is a dedicated professional who has been recognized with numerous awards throughout his career. He has advanced the field through clinical research, has several patents in cardiac ICD therapy, and is an ABIM Board Examiner for Cardiology, helping to set the standard for board certification. Committed to serving the local community, Dr. Chow founded his private practice in San Jose and has since become a trusted healthcare partner in the region. His practice is known for providing comprehensive, expert, and compassionate cardiac care.

Double Board-Certified in Both Cardiac Electrophysiology and General Cardiology

Our Health Services

We strive to provide the most current treatment options for patients in cardiology and electrophysiology, and a personal compassionate approach to patient care.


  • Stress testing
  • Nuclear cardiac imaging
  • ECHO
  • Carotid duplex ultrasound
  • Heart monitoring (Holter, Event monitor, MCOT)


  • Electrophysiology studies 
  • Catheter ablation for Atrial fibrillation, SVT and VT
  • Pacemaker and ICD implant
  • Cardiac resynchronization for heart failure (Bi-ventricular devices)
  • Implantable loop recorders
  • Tilt table testing
  • Cardioversion


Patients taking the blood thinner warfarin (Coumadin) require close monitoring of blood levels for both safety and effectiveness. Our office coumadin clinic provides convenient “on-the-spot” testing of blood levels, with immediate feedback on whether dose adjustment is required.

This is far more efficient than the “usual” practice of referring patients to a commercial lab for blood draw, waiting for those results to reach their doctor, and for the doctor to contact them with dosing adjustments. Delays or breakdowns in communication can result in patient complications. Our approach eliminates this inefficiency by in-person testing with immediate patient feedback on dosing adjustment.


In the past, pacemakers and ICDs would simply be followed at the time of office visits every 6-12 months. However, we follow pacemakers, ICDs and implantable loop recorders using a combination of in-office device checks and remote home monitoring technology.

This comprehensive approach provides patients with the best assurance that any problems will be caught quickly and dealt with in a timely manner, thus avoiding complications resulting from delay.

San Jose Hospitals and Surgery Centers

Dr Chow has hospital privileges at both Good Samaritan Hospital (GSH) and Regional Medical Center of San Jose (RMC). His primary office is located adjacent to RMC, but he sees patients and does invasive procedures at both GSH and RMC. Outpatient (i.e. elective) electrophysiology procedures are usually scheduled at GSH—this would include catheter ablation of atrial fibrillation, SVT and other arrhythmias. Implantation of cardiac devices—pacemakers, ICDs—will be done either at an outpatient surgery center or one of the above hospitals. The implantation of loop recorders are minor procedures done in the office. Ultimately, however, details regarding where and how procedures are to be performed comes down to a discussion between Dr Chow and the individual patient—every patient is unique.

AF Ablation

Catheter Ablation

SVT Ablation

3-D modelling of the heart performed by Dr Chow during an ablation procedure for atrial fibrillation (AF). Red dots depict the location of catheter ablation lesions applied around the pulmonary veins (blue and yellow structures) in order to block the abnormal signals from within the pulmonary veins that trigger AF. This patient had complete cure of his AF following ablation, and no longer requires medication to control heart rhythm.
