Successful treatment of severe orthostatic hypotension with cardiac tachypacing in dual chamber pacemakers

Pacing Clin Electrophysiol. 2000 Jan;23(1):137-9. doi: 10.1111/j.1540-8159.2000.tb00661.x.


Orthostatic hypotension is an evolving and disabling disease usually observed in elderly patients with dramatic consequences on morbidity, mortality, and impairing the quality of life. We studied the effects of the pacing rate and AV interval on the blood pressure drop in the upright position in two patients with previously implanted pacemakers for sinus node dysfunction. Although the AV interval did not affect the blood pressure drop in the upright position, tachypacing at 100 paces/min improved it dramatically and prevented syncope. Cardiac tachypacing is a useful therapeutic option in severe refractory orthostatic hypotensive patients, especially those with chronotropic incompetence.
