I have been short of breath recently, and my heart is beating very fast, sometimes during the day. More and more frequently recently, before going to bed.

Hello, the palpitation you said is also called palpitation in medicine. Palpitation is a strong, rapid and irregular heartbeat of the heart.

It is normal for the heart to have palpitations for a few minutes after strenuous exercise, so don't worry. If you smoke, drink too much coffee or tea, your heart is stimulated by caffeine or nicotine, and you are nervous, you will have palpitations. If it were not for the above reasons or the influence of exercise and emotion, palpitation would last for many days. If you still have difficulty breathing or other phenomena, you should see a doctor.

Judging from what you said, it is not ruled out that it may be paroxysmal tachycardia. At present, it is recommended to go to the hospital for 24-hour dynamic electrocardiogram and other related examinations. Tachycardia can also be caused by some diseases, such as fever, anemia, pregnancy, hyperthyroidism, heart failure, shock and autonomic nervous dysfunction. It is suggested to go to the hospital for a detailed examination in time to clarify the reasons for the rapid heartbeat so as to treat the symptoms. At this time, it is mainly necessary to treat the cause and choose drugs under the guidance of a doctor. If necessary, consider radiofrequency ablation.

I hope I can help you and wish you health and happiness.
