The pharmacological effects of suxamethonium and pancuronium on the cardiovascular system may vary and therefore alter the haemodynamic response to intubation. The arterial blood pressure, the heart rate and the rate pressure product were measured as parameters of haemodynamic change in forty adult ASA. I and II patients undergoing laryngoscopy and endotracheal intubation in a randomised contro...

Various diagnostic methods have been used to evaluate hypertensive patients under physical and pharmacological stress. Several studies have shown that exercise hypertension has an independent, adverse impact on outcome; however, other prognostic studies have shown that exercise hypertension is a favorable prognostic indicator and associated with good outcome. Exercise hypertension may be encoun...

The aim of the present study was to compare the responses of blood pressure, heart rate, and rate-pressure product of hypertensive women using beta-blockers with healthy controls during resistance exercise (by the end of the concentric phase of the contractions) and in the postexercise period (5 and 30 minutes after). Ten untrained normotensive women (N) and 10 mildly hypertensive females recei...

The patients suffered no adverse effects when they were switched between treatment schedules. The average number of episodes of angina during the 4 weeks on long-acting propranolol was 7.3 and on standard propranolol, 6.3. Average nitroglycerin consumption was 5.8 and 4.9 tablets during therapy with these two drug programs. The resting values for heart rate, systolic blood pressure and rate-pre...

The effect of timolol vs placebo on the frequency of anginal episodes, nitroglycerin consumption and exercise performance was investigated in a double-blind, randomized, crossover study in 23 patients with angina pectoris. The optimal dose of timolol (10-30 mg twice daily) for each patient was titrated by exercise studies. Compared with placebo, timolol decreased the weekly number of anginal at...

OBJECTIVE To investigate potential associations between resting heart rate, blood pressure and the product of both, and the brachial-ankle pulse wave velocity (baPWV) as a maker of arterial stiffness. METHODS The community-based "Asymptomatic Polyvascular Abnormalities in Community (APAC) Study" examined asymptomatic polyvascular abnormalities in a general Chinese population and included part...

background: movement dysfunction may be expressed in terms of symptoms experienced in non-physiological postures, and head-down crooked kneeling (hdck) is a posture frequently assumed by muslims during prayer activities. the purpose of this study was to investigate the cardiovascular responses in the hdck posture. methods: seventy healthy volunteers, comprising 35 males and 35 females, particip...
