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).
Stage three (late): hearing loss; balance difficulties; tinnitus. In the later stages the hearing loss increases and often the attacks of vertigo diminish or stop. Hearing loss can be severe and distortion, loudness discomfort and recruitment can be a problem. There is permanent damage to the balance organ in the ear and significant general balance problems are common, especially in the dark. MÃ©niÃ¨reâs disease causes damage to the hair cell receptors in the inner ear.
