Patient
Dr John Zimmerman MD is a very smart and caring expert in heart rhythm and blood pressure disorders. He performed a painless ablation on my erratically beating heart at Good Samaritan which was tiring my heart and fatiguing me as well. When I woke up after surgery my heart was calm and all symptoms were gone!!! He truly has his patients best interest at heart. I realize and thank him and God for his help . Matt Riedel
