The most common arrhythmia is atrial fibrillation, which happens when the heart's upper chambers (atria) receive irregular electrical impulses. As a result, the beat becomes irregular and rapid. A heart rate of 100 to 175 beats per minute can be caused by atrial fibrillation. Atrial fibrillation causes confusion, dizziness, tiredness, and fainting. Other factors that enhance the incidence of AF include the increased global prevalence of obesity and cardiac disorders, in addition to COVID-19's recent development and influence on AF.
