Circadian rhythm of blood pressure in patients dependent on ventricular demand pacemakers.
The reported circadian rhythm of blood pressure variability with a rise in pressure before awakening has been the subject of controversy. Previous studies have suggested that since heart rate continues to fall before awakening while blood pressure is rising these physiological variables are subject to different control mechanisms. To evaluate further the dissociation of heart rate and blood pre...
متن کاملAltered circadian blood pressure rhythm in patients with Cushing's syndrome.
The circadian blood pressure rhythm was compared in patients with Cushing's syndrome, essential hypertension, and primary aldosteronism. In patients with essential hypertension or primary aldosteronism, a clear nocturnal fall in systolic and diastolic blood pressure and heart rate was observed. This fall was seen in untreated subjects as well as in patients receiving combined treatment with a c...
متن کاملBlood pressure circadian rhythm and heart rate turbulence in hypertensive patients: relationship with left ventricular hypertrophy
Objective To investigate the relationship of blood pressure circadian rhythm with myocardial hypertrophy and the changes of autonomic nerve function in patients with essential hypertension (EH). Methods Eighty-two female patients with essential hypertension (EH) underwent 24-hours ambulatory blood pressure monitorings (ABPM), dynamic electrocardiogram (Holter) and echocardiography examination. ...
متن کاملBlood pressure circadian rhythm in essential hypertension.
1. Both systolic and diastolic blood pressure show a well defined circadian variation in ambulatory hypertensive subjects. 2. Blood pressure is highest in the mid-morning (10.00 hours) and lowest during sleep at 03.00 hours. 3. Treatment with oxprenolol (taken during the day) reduces daytime blood pressure but is less effective during the night and early morning.
متن کاملKidney and circadian blood pressure rhythm.
Association between nondipper pattern of circadian rhythm of blood pressure (BP) and impaired renal capacity to excrete sodium into urine was confirmed by Bankir et al1 in this issue of Hypertension based on a large number of subjects. Although this association has been observed in small studies,2,3 their study1 is the first to show it in a large-scale setting, and, therefore, is highly welcome...
