Methods: A comparative analysis female and male aged 13.9 15.4 years carried out (57 53 2020). We used a spiroartheriocardiorythmograph allowing recording heart rate (HR) bl...

Introduction: This study aimed to investigate the diurnal intraocular pressure fluctuations under dehydration conditions and the relationship between the intraocular pressure fluctuations and blood pressure. Methods: The intraocular pressures (IOP), body weights, as well as systolic and diastolic blood pressures (SBP, DBP) of 36 fasting healthy volunteers were recorded at 8:00 a.m. and 5:00 p.m...

BACKGROUND Has been reported that patients exhibiting prolonged paced QRS duration tend to have more serious heart disease, and the paced QRS duration can be an effective indicator of impaired left ventricular function. However, the acute and chronic hemodynamic effects of paced QRS duration and pacing sites during right ventricular (RV) pacing remain unknown. METHODS A total of 14 patients w...

Introduction: Noise, as the most common pollutant in the industrial environment, can lead to hearing loss and negatively affect other organs such as the cardiovascular system. Cigarette smoking is a popular habit among some workers, and can also have a negative effect on the cardiovascular system. This study aimed to investigate the effect of simultaneous exposure to noise and cigarette smoke o...

In this report we describe the distributions of blood pressure and its associations in adolescence. Six hundred and twenty-five subjects aged 13 to 18 were drawn from three general practices in different urban and rural settings. Systolic pressures were higher and rose with age in boys (mean = 119 mm Hg) compared with girls (mean = 114 mm Hg), who showed no age association. Diastolic pressures ...

introduction: hypertension is the most important modifiable cardiovascular risk factor. hypertension is the leading global risk factor for mortality and as the third leading risk factor for cardiovascular disease burden. this survey has been conducted to determine the prevalence of hypertension among the inhabitants of 25-64 aged in 17th zone of tehran, selected as population lab region. method...
