Abstract
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, respectively, to access the effect on the electrocardiogram. All waves of Lead I, Lead II, Lead III, aVR, aVL and aVF in electrocardiographs were recorded before and after 30 days exposure of fluoride. A significant (P < 0.05) increase in P-R, Q-T and S-T intervals were observed in goats of group 1 as compared to their pre treatment values. The T wave duration was also significantly (P < 0.05) prolonged and as a result, bradycardia was observed after subacute exposure of fluoride for 30 days in group 1. But, in group 2, no such changes were observed. On the basis of results, it may be concluded that subacute toxicity of fluoride produces significant changes in different waves of electrocardiogram and aluminium sulphate has ameliorative efficacy.

Changes of the heart muscle due to chronic fluorosis. Part 1: Electrocardiogram and cardiac x-rays in inhabitants of a high fluoride zone
1) The author examined inhabitants of a high fluoride zone (Shionoe village, Kagawa Prefecture, and Odani villAge, Sanyo town, Okayama Prefecture). ln residents of these zones , greater myocardial damage was detected electrocardiographically and dilatation of the cardiac sillouette roentgenograpbically than in n0n-fluoride areas. 2) The myocardial damage appears to

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,

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

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

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, 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 & 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 & 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 & 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
