cardiac arrhythmias, cardiomyopathy


Michael Ralston, MD is a pediatric cardiologist at Dayton Children's Hospital. Dr. Ralston was born and raised in Springboro, Ohio and graduated Valedictorian of his high school class. He attended The Ohio State University College of Medicine where he completed his medical education and received honors in physiology and radiology. Following college, he spent his internship and residency at Columbus Children's Hospital (now renamed Nationwide Children's Hospital). He completed his fellowship in Pediatric Cardiology at  Cincinnati Children's Hospital. After  his fellowship, Dr. Ralston became a pediatric cardiologist at Dayton Children's because he knew Dayton would be a great place to raise a family. Dr. Ralston is board certified in both pediatrics and pediatric cardiology. He has a special interest in myocardial imaging and caring for children with congenital heart disease and arrhythmias. When asked why he chose to specialize in pediatric cardiology he said it was because of the tremendous impact he can make on a child's life who has congenital heart disease. One of his favorite things about working with children is their love of life is infectious. Outside of the hospital, Dr. Ralston enjoys collecting quotes, running and soccer.

Everyone was great. We did wait a bit, but tests were done and we left with all of our questions answered.

The doctors and specialists are extremely helpful, they are super thorough. They make sure everything is understandable and are patient. I love seeing doctor rostlan, he is great with his patients. The ultrasound technician was wonderful and super helpful and so fun! The technician and doctor both took extra time to make sure everything was perfect. My son has vsd, and they couldn't find the hole in his heart, but could hear the murmur.. so they went back and did another ultrasound to find the issue. They did find the hole (doctor rostlan and the technician) but it was very small. I was very thrilled to have a great team of doctors looking after my son . Thank you so much!
