i understand you are worried. please do not worry. sinus tachycardia is just fast heart rate and yours is just slightly elevated. probably you were a little anxious during the time of the examination. st and t changes are often seen in normal healthy patients. it could be due to some medications. it is highly unlikely that you have any cardiac related issues at this age. but if you have experienced any chest pain of recent or shortness of breath then it could be a cause for worry. if you do have symptoms such as shortness of breath or chest pain then i will advise that you repeat the ekg test as a conclusion because it cannot be drawn from one ekg test result. for further information consult a cardiologist online --> <link>
though my ekg showed sinus tachycardia why did not my doctor worry about that?
