Abstract
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, and V10 were recorded in the electrocardiographs of the sheep. All waves were seen in all derivations. The P-Q interval was significantly (p<0.05) prolonged and sinus bradycardia was observed in the sheep with fluorosis. As a result of this, the number of heart beats was decreased significantly (p<0.05); that is, the number of heart beats was 110 +/- 15 in the control group and 75 +/- 10 in sheep with fluorosis.

Observations on electrocardiograms in a population living in a region with coal-burning-borne endemic fluorosis after comprehensive controls
Objective: To observe the electrocardiogram (ECG) changes in the population living in the region with coal-burning-borne endemic fluorosis (EF for short) after comprehensive controls. Methods: People living in a region with coal-burning-borne EF in Bijie City of Guizhou Province were selected and then divided into 4 groups according to the

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

Alterations in electrocardiographic parameters after subacute exposure of fluoride and ameliorative action of aluminium sulphate in goats
Fluorosis or crippling disease is one of the existing environmental challenges for animal and human beings in most parts of the globe. In the present study, sodium fluoride alone and with aluminium sulphate (ameliorative agent) was administered orally daily for 30 days in healthy goats of group 1 and 2,

Electrocardiographic evaluation in patients with endemic fluorosis without clinically evident heart disease
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,

[Hydrofluoric acid injury analysis on the health of workers].
Objective: To analyze the damage caused by hydrofluoric acid to the health of operating workers and to explore health monitoring indicators. Method: Occupational health examinations were carried out on 536 hydrofluoric acid operating workers from the etching process at a certain factory, and 256 persons in the control group. Results: Among the

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, 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 & 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 & 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
