Is rapid heart rate with high blood pressure dangerous?

Question
Hello doctor,
I am 23 years old this year, recently my heart has abnormal phenomenon. From time to time, the heart beats very fast (120-140 bpm) and systolic blood pressure also increases (140-150) even while sitting. Usually each episode will last about 1 hour. I didn't feel any chest pain or dizziness, but my heart beat fast and my blood pressure increased, making it very uncomfortable in my body, sometimes it was difficult to breathe. I have had thyroid and Cortisol tests and an echocardiogram, all normal. The doctor asked me, is it dangerous to have a fast heart rate with high blood pressure?

Hello,
To the question "Is a fast heartbeat with high blood pressure dangerous?", the doctor would like to answer as follows:
You went to the doctor and did an echocardiogram, thyroid hormone test, quantification. Cortisol results are normal. Your symptoms appear when tachycardia and blood pressure increase, so Holter blood pressure is a good indication to confirm the information combined with the descriptive symptoms, thereby making a diagnosis and appropriate treatment. fit.
However, in a 23-year-old male, it is likely that these changes are not easily diagnosed, especially given their low frequency (eg, only a few days, a few weeks). You need to visit a cardiologist again, the doctor will base on the symptoms and the frequency of symptoms to have a monitoring method and make an appropriate diagnosis.
If you still have questions about heart palpitations, you can go to the 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!
