Dr. T took his time ask questions about my afib and the previous provider’s treatments. He listen to my research and we can to a quick conclusion with a simple treatment plan. The med he put me on worked we had one follow up and adjust the timing of the doses. His office is super responsive and easy to work with. High recommend him and his office.

Dr. Tiongson is a member of an amazing team of cardiac electrophysiology doctors and support personnel at Mission Heritage in Mission Viejo. They recently treated me for an abnormal heart rhythm that required 2 ablations to restore to normal. He performed the procedure on left side in a very challenging area. He outlined the risks and benefits very clearly. I have tremendous confidence in Dr. Tiongson and would recommend him and his team to anyone with an arrhythmias condition.

Post a ResponseAre you Dr. Tiongson?
After years of random episodes of SVT, some so severe I'd end up in the CICU, Dr. Jay Tiongson suggested cardiac ablation to disrupt my "short circuit" pathway. I agreed and couldn't be happier with the results. Jay and the Mission Hospital Cath Lab staff changed my life and I will always be thankful to them. If you know someone with heart rhythm issues, please have them read my review.
Sincerely,
Lee Korman

Dr. Tiongson has helped me regain my health and strength after an arduous surgery and recovery process. He was tenacious in diagnosing and treating my multiple heart conditions, and the results were successful. I can't say enough about his caring, compassionate manner and his willingness to take time to explain all the details. His staff reflect the same attitudes. He is now helping my husband, and I couldn't be happier for the care we are receiving.
