Paroxysmal atrial tachycardia may be caused by several different things. The fast rate may be triggered by a premature atrial beat that sends an impulse along an abnormal electrical path to the ventricles. Other causes stem from anxiety, stimulants, overactive thyroid, and in some women, the onset of menstruation.
Sudden hearing loss is associated with vertigo in between 20 to 60% of patients (Rambold et al, 2005). The wide spread probably depends on what you define as vertigo -- a little bit of dizziness, or a profound sensation of rotation. Patients with vertigo also usually have worse hearing (Niu et al, 2015).
Ear dizziness may appear as a whirling or spinning sensation (vertigo),. It may last seconds, minutes or hours, and is frequently aggravated by head motion or sudden position change. Nausea and vomiting may occur but one does not lose consciousness as a result of inner ear dizziness. DIAGNOSING THE CAUSE OF DIZZINESS.
