My son who just turned 18 has asymptomatic irregular heartbeats occasionally. MOst noticeable when he is at rest. He does not feel them nor does he have any disturbing accompanying symptoms. The only way they were found out was I do check my childrens pulse once in awhile to make sure that everything this is fine. ONLY reason I check their pulse sporadically is because I am a 25 year PVC sufferer who has finally learned to live with them and I must say I am doing very well with this! I took my son to our family GP and she gave his heart a long listen with the stethoscope and also asked him some questions. Later she called me at home and told me that he was fine. His heart sounded good with no abnormal sounds and she told she would not order any more tests because he seemed a little alarmed when she was checking his heart and she doesnt want him to get obsessed with his heart. I agree with this, I dont want to get him worried, but since he is totally asymptomatic is this okay? Should I insist on more testing? I guess the main question I would like to ask you is if he had something "wrong" with his heart, would he have some other symptoms that he would be aware of? Also doctor, if you were to see an asypmtomatic 18 year old in your office with same history as above, would you also not order further tests? I guess I just need some good reassurance so I can just move forward and stop worrying. Thanks for your time.
