Hello, this is called palpitation, which is usually caused by a sudden lack of blood supply to the heart. Most of the reasons are caused by mental stress or fatigue. Normal people can also have occasional seizures. If you don't feel at ease, you can go to the hospital for a check-up, or find Chinese medicine to recuperate.

It is suggested to work and rest regularly, don't stay up late, don't be overworked, drink more boiled water, keep warm and keep out the cold, and wish you good health.

You can search the video of "Yangshengtang Cardiovascular Disease", which is helpful to you.
