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.

A comparative study on systolic time interval of populations in mild and severe endemic fluorosis regions
Comparative study on STI of populations in regions mildly and severely affected by endemic fluorosis demonstrated significant differences between these two affected regions in the detection rate of abnormal STI as well as QS2 and PEP/LVET, indicating that endemic fluorosis may injure the heart.

Effects of chronic fluorosis on electrocardiogram in sheep
This study was carried out to evaluate the effects of chronic fluorosis by means of the electrocardiograms in sheep. Ten sheep with fluorosis living around a volcanic mountain (Tendürek Mount) in East Anatolia in Turkey and 10 healthy sheep were used. Leads I, II, III, aVR, aVL, aVF, V2, V4,

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

Clinical and hygienic evaluation of the combined effect of vibration and fluoride in humans
By L. Ya. Tartatovskaya, G.N. Samokhvalova, A.G. Antropov Medical Science Centre of Prophylactics and Protection of the Health Workers in Industrial Enterprises, Ekaterinburg, Russia. The study of the combined action of vibration and intense noise, muscular loads and cooling has made it possible to assess the probability of the development of vibration

Effects of sodium fluoride on the electrocardiogram of male rabbits
Effects of fluoride (F) on electrocardiogram (ECG) values were determined in ten healthy adult male New Zealand white rabbits. After the initial ECG values were measured, the rabbits were administered 20 mg NaF/kg body weight by oral intubation for two months, and the new ECG values were determined. There was

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

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 & 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 & 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
