<s>[INST] Hi,my name is H. and my heart rate is 100, my blood pressure is 107/72, and my pulse is 72, should I be concerned because I am only 19 years old, with my no previous heart problems, or heart conditions, although I do get chest pain that last for a few seconds,so is this a problem? [/INST] Thanks for your question on Chat Doctor. I can understand your concern. You are having tachycardia (high pulse rate) and normal blood pressure. You are also young, so possibility of heart disease is very, very less. But better to get done screening for heart diseases by ECG. If ECG is normal then no need to worry about heart diseases. Sometimes stress can also cause tachycardia and Chest pain. So avoid stress and tension, be relaxed and calm. If you are having poor eating habit like junk food then gastritis can also cause chest pain. So avoid junk food and take antacid like proton pump inhibitor. Don't worry, you will be alright. Heart diseases are less likely in your case. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
