Be sure to go to the hospital and let the doctor give you a good examination. This is something to pay special attention to. Second, for atrial fibrillation, pay attention to it. Because atrial fibrillation can lead to heart failure, can reduce the heart beat volume, more importantly, can lead to thromboembolism, atrial fibrillation is a very serious danger, may cause death, this is very important. For the general public, we, the patients and the people, now pay attention to the hazards of atrial fibrillation, go to the hospital for examination, communicate with the doctor, one is to prevent embolism, one is to control the ventricular rate, and can also consider radiofrequency ablation. The third aspect is premature beats. For premature beats, we should first determine whether they are organic or functional, and how they affect hemodynamics. Otherwise, the treatment of premature beats is mainly about the control and improvement of the causes and triggers. Do not be too concerned about the number of premature contractions and do not intentionally take more medication because of them. If you have to take medication, it is also better to consult your doctor and not to take health products, not to mention to believe in any non-toxic and side-effect-free drugs.
