Use of the "diving reflex" in paroxysmal atrial tachycardia.
Immersing the patient's face in cold water to induce the "diving reflex" is a quick and simple method of treating paroxysmal supraventricular tachycardia. Patients can be trained to perform the "diving reflex" at home. There are many advantages to this method of treatment when compared to many of the other therapies. Polyuria up to 3 L is often noted during the first 90 minutes of a paroxysmal tachycardia. The diuresis is thought to be due to atrial distention with resultant inhibition of antidiuretic hormone secretion.
