Abstract

Objective: This study was carried out to analyse the electrocardiogram (ECG) in patients with endemic fluorosis. Methods: Fifty six patients with endemic fluorosis and 44 age, sex and body mass index (BMI) matched healthy controls with normal fluoride intake underwent standart 12-lead ECG, urine fluoride level and serum sodium, potassium, calcium and phosphorus determination. Basic ECG measurements and frequency of ECG abnormalities were evaluated. Results: The urine fluoride levels of fluorosis patients were significantly higher than control subjects as expected (1.9 ± 0.2 mg/l vs. 0.4 ± 0.1 mg/l respectively; P<0.001). There were no statistically significant differences between the two groups with respect to age, gender, BMI and serum levels of sodium, potassium, calcium and phosphorus. There were no statistically significant differences between controls and fluorosis patients with respect to heart rate, basic ECG measurements and ECG abnormalities. Results: We concluded that endemic fluorosis has no effect on ECG.

    Our team performed investigations in Yuqing Village and Guanfang Village (1) which were seriously affected by endemic fluorosis, from September to October 1985; those two villages are only 1,500 meters distant from Mangbu District of Zhenxiong County, and the life and production conditions in these two villages are similar to

  • Effects of chronic fluorosis on electrocardiogram in dogs

    The aim of this study was to determine the effects of chronic fluorosis on the electrocardiogram (ECG) in dogs. A total of sixteen mixed breed dogs (8 fluorotic and 8 healthy), 2 to 3 years old and weighing 18–30 kg, were used in this study. The eight dogs with chronic

  • Electrocardiogram analysis of patients with skeletal fluorosis

    To investigate the degree of myocardial damage resulting from endemic fluorosis, electrocardiograms of 136 skeletal fluorosis patients from an endemic fluorosis area were compared with electrocardiograms of a control group of 40 normal patients from a non-endemic fluorosis area. The results show that fluoride in drinking water consumed over time

  • Electrocardiographic studies of the inhabitants in high fluoride districts

    1) In the Aso-volcano district, a higher incidence of myocardial damage based on electrocardiographic studies was found in inhabitants of high fluoride communities than in "nonfluoride" villages. 2) In subjects with mottled teeth, greater myocardial damage was encountered electrocardiographically than in persons without mottling in the Asovolcano district. 3) The authors conclude

  • Impact of chronic fluorosis on left ventricular diastolic and global functions.

    Sixty three patients with endemic fluorosis (36 males/27 females; mean age 33.9+/-8.6years) and 45 age, sex and body mass index (BMI) matched healthy controls (30 males/15 females; mean age 32.7+/-8.8years) were included in this study. Basic echocardiographic measurements, left ventricular diastolic parameters and left ventricular myocardial performance index (MPI) were

  • Fluoride & Myocardial Damage

    Structural damage to the heart resulting from fluoride toxicity has been observed in numerous human and animal studies. The general features of this damage include cloudy swelling, vacuolization or vacuolar degeneration, hemorrhages, interstitial edema, fibrous necrosis, dissolution of nuclei, and thickening of the vessel walls in the heart muscle (Basha

  • Fluoride & Arteriosclerosis

    Healthy arteries are flexible and elastic, allowing efficient transfer of blood and nutrients from the heart to the rest of the body. Arteriosclerosis refers to a stiffening of the arteries, including loss of elasticity. This is a slow, progressive disease that may begin early in life from damage to the

  • Fluoride & Electrocardiogram Abnormalities

    An electrocardiogram (ECG) is a diagnostic test that measures the electrical activity of the heart. An ECG can reveal heart rate, heart rhythym (i.e. steady or irregular), and the strength and timing of the heart’s natural electrical signals. ECGs are described in terms of “waves” (e.g. amplitude and duration). Problems

  • Fluoride & Arterial Calcification

    The major change involved with cardiovascular disease is development of atherosclerosis in critical arteries, which is partially characterized by vascular calcification. The level of coronary artery calcification is thought to be the most important indicator of future cardiovascular events. Increased arterial calcifications have frequently been reported in those with skeletal fluorosis

  • Fluoride, Blood Pressure and Hypertension

    Individuals with blood pressure readings that exceed 140/90 are considered hypertensive. Hypertension can increase the risk of stroke, heart attack, heart failure, aortic aneurysms, and peripheral arterial disease. An association between increased fluoride in ground water and increased prevalence of hypertension has been observed, especially among adult males (Amini et
