DR. Nishikawa is a very knowledgeable cardiologist and will take to time to totally explain your tests and test results. He will make suggestions on how to proceed with your issue and believes in thorough testing to pinpoint your issue. If the first test does not reveal the issue he will run other test and examinations until he is sure of your issue and how to solve it. He is very personable and I recommend him highly.
