Atrial fibrillation is categorized into five types: first diagnosis of atrial fibrillation, paroxysmal atrial fibrillation, persistent atrial fibrillation, long-term persistent atrial fibrillation and permanent atrial fibrillation, etc. The atrial fibrillation in question here should refer to paroxysmal atrial fibrillation, and paroxysmal atrial fibrillation that strikes once every few days or weeks and each time will last for more than 24 to 48 hours is considered as a frequent attack. Paroxysmal atrial fibrillation is considered frequent if it occurs once every few days or weeks and lasts for more than 24 to 48 hours each time. When patients experience frequent attacks, they should go to the hospital in a timely manner because frequent attacks can easily lead to the formation of blood clots in the heart, which can lead to serious complications such as myocardial infarction. Paroxysmal atrial fibrillation is a type of atrial fibrillation, which usually manifests itself as irregular and varying heart rates during an attack, causing symptoms such as dizziness, palpitations (rapid heartbeat, often accompanied by panic), tightness in the chest, shortness of breath, and fatigue. It is recommended that patients with paroxysmal atrial fibrillation should strengthen self-testing, consult a doctor in a timely manner when frequent episodes of abnormal conditions occur and receive treatment according to the doctor’s instructions, and avoid triggers of paroxysmal atrial fibrillation such as heavy drinking and excessive exercise in daily life.
