Supraventricular tachycardias include atrial fibrillation, atrial flutter and paroxysmal supraventricular tachycardia. Supraventricular tachycardias include atrial fibrillation, atrial flutter, and paroxysmal supraventricular tachycardia. Re-entry is also responsible for most paroxysmal supraventricular tachycardia, and dangerous ventricular tachycardia. Benign paroxysmal positional vertigo (BPPV) is a condition resulting in acute symptoms of vertigo. It is sometimes known as paroxysmal atrial tachycardia (PAT). Treatment for paroxysmal nocturnal dyspnea depends on the underlying cause. Reentry can produce single ectopic beats, or it can trigger paroxysmal tachycardia. Attacks of the movement disorder paroxysmal dyskinesia may be taken for epileptic seizures. A doctor diagnosed her with having paroxysmal tachycardia and sent her home. The paroxysmal cough precedes a crowing inspiratory sound characteristic of pertussis. Eculizumab is used to treat atypical hemolytic uremic syndrome (aHUS) and paroxysmal nocturnal hemoglobinuria (PNH). It was initially approved to treat paroxysmal nocturnal hemoglobinuria, a rare blood disorder. This is the case in both cold agglutinin disease and cold paroxysmal hematuria. There are many theories dealing with the pathophysiology of paroxysmal sympathetic hyperactivity. This results in a wave of depolarization known as a paroxysmal depolarizing shift.
