Abstract
Summary: The technique of non-invasive blood pressure monitoring was used to compare the 24-hr control of blood pressure in 10 patients with essential hypertension taking either twice daily propranolol or a once daily long-acting formulation of propranolol (propranolol LA). Both drug regimes produced smooth control of blood pressure and heart rate through the 24 hours and significantly reduced blood pressure and heart rate on bicycle ergometry tests. There was no significant difference between the two treatments. The non-invasive oscillometric method of measuring 24-hr control of blood pressure provides an alternative to ambulatory intra-arterial monitoring.
