<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi! My son always has cold hands,which somewhat concerns me. Today as part of our homeschooling in science we measured their pulse rate; I then used my blood pressure monitor to see how close they were to being correct. My sons was rather strange . His systolic was 131 which seems rather high to me and his dystolic was 59 which seemed rather low, and his pulse was only 50 which seemed really low for a teen Should I be worried!?  <response>: Dear- It is important to monitor your sons blood pressure and heart rate. The difference between systolic and diastolic is borderline high, it could be due to an isolated situation for which I would recommend getting records of a daily measurement at the same time for 2 weeks. If still like that, it might be beneficial to have a complete laboratory examination and cardiovascular evaluation with an electrocardiogram and echocardiogram. However, most of the time it is because the kid does a lot of exercise and the HR gets slow. I hope my answer will be helpful
