My pre-op showed a low heart rate and an abnormal EKG. I had a 24 hour heart monitor and the cardiologist approved my surgery. When I saw my hematologist he said, “I am not a cardiologist but if you were a member of my family I would encourage you to cancel your surgery and see a different cardiologist.” So I saw a different cardiologist who was very thorough. I had an Echocardiogram, another EKG. He then ordered a MRI stress test and a 30 day heart monitor. I learn the results in September. For now the hip replacement is canceled again indefinitely.
