I wouldnt worry to much about the heart rate normal resting is 60-100. Ask about the echo if its normal no worries. That will give you ton of good info, ejection fractio(normal 50-70%) wall thickness, if there is any thing wrong with your valves ( leaky or tight). One of the most common findings a lot of people have is mitral valve prolapse in most cases benign, just something to watch. If the heart rate worries you it is something you can check on your own to. Hopefully everything checks out.
