[Paroxysmal atrial fibrillation and flutter and "occult" arterial hypertension. The importance of the ambulatory monitoring of the blood pressure. Apropos 2 cases].

The authors describe two hypertensive patients with paroxysmal auricular flutter or fibrillation. The arterial hypertension was suspected because of a hypertensive response in a treadmill stress test, confirmed by a 24-hour blood pressure ambulatory monitoring and there was no damage in target organs. They focus that auricular flutter/fibrillation may be related to "occult hypertension".
