Ambulatory blood pressure measurement in a patient with pheochromocytoma by means of finger volume-oscillometric device.

A new device which measures ambulatory blood pressure was used to detect paroxysmal hypertension in patients with pheochromocytoma. The device uses a finger volume-oscillometric technique for the long-term measurement of indirect arterial pressure at desired intervals. The device clearly detected crises of hypertension of short duration. This device is invaluable for the detection of paroxysmal hypertension in patients with pheochromocytoma.
