Re: Can you have a mostly normal heartbeat and have heart trouble?
Yes, you can have heart issues and a "normal" heart rate at specific times.
A heart murmur is a sound heard as blood flows through the heart valves. I have moderate-severe mitral valve regurgitation, and present cardio doc says he can barely hear the sound of interest.
Over the years I have had several physical exams and only one doctor about 25 years ago stated I had a murmur, but don't worry. The sound could have been slight and missed over a period years. I don't know.
If you have a valve issue where there is back flow of blood into the receiving chambers, that would compromise the blood put into circulation. With a low output but sufficient blood into the areas of priority (brain, heart, etc.) the skeletal muscles and other areas receive less blood causing fatigue. However, if you have heart pains that could indicate the heart isn't receiving sufficient blood during specific times.
You should at least get an echocardiogram to rule out any serious valve problem. An EKG and stress test if warranted.
