Ask
Hello doctor,
This year, I am 21 years old. I often have symptoms of chest tightness, feel my heart beat fast, my hands and feet sweat easily. I work as a security guard, I sleep overtime from 3am to 11pm. I just started having these symptoms a few days ago. I'm translating, so I can't go to the doctor. I want to ask the doctor what is the cause of the heart palpitations, chest tightness, sweating extremities? I hope you can answer me, thank you.

Hello,
With the question “What is the cause of heart palpitations, chest tightness, sweating extremities? , the doctor would like to answer as follows:
You are young and have symptoms of fatigue, heart palpitations, chest tightness, sweating in the extremities from time to time, work changing biological time can make you anxiety as a symptom of autonomic dysfunction. However, you will need an electrocardiogram to rule out cardiovascular disease.
Because of the epidemic situation and social distancing, you can't go to the doctor, you should create conditions for yourself to relax better, drink more water and you can buy Magne B6 oral medicine, take it every day 1- 2 tablets after eating for about 10-20 days. If your condition is not stable, you definitely need to go to the hospital right away.
If you still have questions about heart palpitations, you can go to a hospital under Vinmec Health System for further examination and advice. Thank you for trusting and sending questions to Vinmec. Wish you a lot of health.
Best regards!
