As a result, the heart may beat inefficiently, and the body may receive an inadequate blood supply. Multifocal atrial tachycardia (MAT) is a relatively infrequent arrhythmia, with a prevalence rate of 0.05-0.32% in patients who are hospitalized. Postural tachycardia syndrome (PoTS) is an abnormal increase in heart rate that occurs after sitting up or standing. It is predominantly observed in males and in older patients—in particular, elderly patients with multiple medical problems.
