Atrial flutter is mostly seen in organic heart disease, such as coronary atherosclerotic heart disease, rheumatic heart disease, cardiomyopathy, etc.; for some people with pulmonary embolism, hyperthyroidism, etc., atrial flutter can also occur. For the above factors caused by atrial flutter, usually can not be self-recovery, patients need to actively cooperate with the doctor to take treatment measures. Clinically, atrial flutter occurs in a very small number of healthy people, but the cause of the disease is not clear, and there is a chance that it will recover on its own.
