Abstract
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 be related to the high fluoride content of drinking water.

Analyses of ECGs in 271 cases with dental fluorosis
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

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.

[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

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

Changes of the heart muscle due to chronic fluorosis. Part 2: Experimental studies on the effects of sodium fluoride upon the heart muscle of rabbits
In the electrocardiogram of rabbits given sodium fluoride orally, a pattern of myocardial damage was observed, namely depressed ST, inverted T, prolonged QT interval, multifocal ventricular premature contraction, bundle branch block, and pulmonary P. Histologically, regressive degeneration, cellular infiltration, hyperemia, hemorrhages and thickening of vessel wall were noted in 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 & 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
