Atrial fibrillation is one of the most common cardiac arrhythmias. Patients with atrial fibrillation can perform light physical activities, but prolonged physical activities are not recommended. Atrial fibrillation is most common in hypertension, heart disease, coronary artery disease, hyperthyroidism, etc. In addition to this, atrial fibrillation can be triggered by emotional excitement, surgical procedures, exercise and heavy alcohol consumption. Therefore, if a patient with atrial fibrillation performs heavy or prolonged physical activities, it is easy to lead to complications such as ventricular arrhythmia and thromboembolism, especially cerebral embolism, which is the most serious and can even lead to death. Atrial fibrillation requires long-term treatment, including anticoagulants (e.g., warfarin), antiarrhythmic drugs (e.g., quinidine, procainamide, propafenone, etc.), and ventricular rate control. If atrial fibrillation is triggered by physical activity, it is recommended that you seek medical attention and take medication as directed by your doctor.
