Fast Heart Rate and a Heart murmur?

hi there... its nothing to worry.. i was recently diagnosed with a hole-in-the heart.. they frightened me saying that i shouldnt do strenueus exercises and all... but i ran my cross country, joined and played hockey, have been running for some time, and am still alive! but that does not mean that u dont take care of yr heart... the moment u feel umcomfortable, either stop wad u are doing or reduce the strain that u are putting on yrself for tt moment.. take a deep breath.. continue ONLY if the uncomfortable feeling has gone... if there's anything else, feel free to ask me! Take care! =)
