Is the heart beating fast after the Covid vaccine?

Question
Hello doctor,
After receiving the 1st dose of Covid AstraZeneca vaccine, I had a rapid heartbeat (about 120 times / minute). So the doctor asked me if my heart rate is fast after the Covid vaccine is okay? I thank you doctor.

Hello,
With the question “Is heart palpitations after Covid vaccination okay? , the doctor would like to answer as follows:
If you are only after the Covid 19 vaccine, your heart rate is 120 times l / min, you should monitor more, relax better, if after 2 days of injection, your heart rate Not fast anymore is normal. Now, if the heart is still beating fast and other symptoms are present (fatigue, chest tightness, shortness of breath, ...) then you should have an additional electrocardiogram to confirm the diagnosis.
If you still have questions about heart palpitations after Covid vaccination, you can go to a hospital of 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!
