Short-term blood pressure variability has been studied extensively with monitoring techniques. To assess whether or not and to what extent average 24-hour blood pressure varies when repeatedly recorded, 12 mild to moderate hypertensive subjects underwent 3 non-invasive blood pressure monitorings at monthly intervals. When the average 24-hour blood pressure(More)
BACKGROUND/AIMS This work focuses on recording, processing and interpretation of multichannel surface EMG detected from the external anal sphincter muscle. The aim is to describe the information that can be extracted from signals recorded with such a technique. METHODS The recording of many signals from different locations on a muscle allows the(More)
OBJECTIVES The objective of this work was to investigate the distribution of the innervation zones of the motor units that make up the external anal sphincter (EAS) in healthy males and females. METHODS A cylindrical probe carrying a circumferential array of 16 electrodes was used to detect the generation, propagation and extinction of individual motor(More)
OBJECTIVE Influence of sacral nerve modulation (SNM) on cerebral somatosensory evoked potentials (SEP) was determined in patients with incontinence and constipation. BACKGROUND Selection of patients with incontinence and constipation for SNM could be improved. METHODS The latency (ms) of SEP induced by pudendal nerve stimulation was compared before (T0)(More)
Exercise training is currently recommended in the management of mild hypertension, but the relationship between training and ventricular arrhythmias has never been investigated in hypertensive subjects. Forty hypertensive sportsmen were studied by means of 24-h ECG Holter monitoring and the results were compared with those obtained in 40 sedentary(More)
To study the mechanisms of the blood pressure changes during weight-lifting, three hypertensive and five normotensive body-builders underwent continuous intra-arterial monitoring. In two subjects (one normotensive and one hypertensive), intrathoracic and intra-abdominal pressures were also measured. Extremely high blood pressure elevations of up to 345/245(More)
In the present paper the problem of the normalcy limits of whole-day ambulatory blood pressure has been faced by evaluating the difference between casual and ambulatory blood pressure in a population of 522 subjects with blood pressure values covering the whole blood pressure range. On the basis of the casual blood pressure levels, 60 subjects were(More)
Purpose of the study was to investigate whether and to what extent blood pressure variability and average night-time blood pressure are related to cardiovascular complications in hypertension. To this aim 60 normotensive and 462 hypertensive subjects were studied by means of non-invasive 24 hour blood pressure monitoring, using either the Avionics, or the(More)
To assess the clinical significance of the blood pressure reaction to orthostatic posture, 55 normotensives and 369 subjects with different degrees of hypertension were studied with non-invasive 24-hour blood pressure monitoring. During the recordings blood pressure response to standing was evaluated at 8 a.m., and at 2, 4 and 7 p.m. All subjects were(More)
