Dr O'Sullivan is a very nice man. However he was not aware I was using Metropolol on a daily basis. He thought I took it as needed. He himself put me on this med.After stating this medicine did not really affected my tachycardia, he suggested a quick releasing medicine as needed. I reported to him that my blood pressure would tank due to being a triatleet, I have a low bp.He acknowledged that and suggested a increased salt intake to counter that (really?) He then proceeded to advice for me a stating due to high cholesterol. Since I was not for that he suggested to fo a heart calcium test. Once I was home I looked in "MyChart" to realize I had that test in May 2026 and the result was 0. No need for stating there. Long story short. I don't feel I was heard and I lost all confidence in him. I will look for another office to monitor my heart in the future
