Possibly: the #1 cause of postural tachycardia is dehydration. As u had been sleeping all night, you probably were not drinking water then too, and typically one is thirsty on awakening. Further given that it resolved so quickly speaks to it likely have been a normal rhythm just fast as u r young and likely don't have any structural heart disease.
