background: cardiac manifestations that occur in a majority of patients with organophosphate (op) poisoning may range from innocuous electrocardiographic manifestations, such as sinus tachycardia, to life-threatening complications, including cardiogenic pulmonary edema and myocardial necrosis. in this study, we evaluated the various electrocardiographic manifestations in patients with op poison...

background: the health transition in india reflects the growing burden of cardiovascular diseases. it is well-known that there are significant and meaningful differences in the measured electrocardiogram (ecg) parameters between females and males. specific to ecg diagnosis and ischemia, reports have indicated a higher number of false positive results in female patients than in male patients. th...

background: an electrocardiogram (ecg) can provide information on subclinical myocardial damage. the presence, and more importantly, the quantity of coronary artery calcification (cac), relates well with the overall severity of the atherosclerotic process. a strong relation has been demonstrated between coronary calcium burden and the incidence of myocardial infarction, a relation independent o...

a survey was carried out in the summer of 1972 in east azerbaijan, northwest iran, to determine the prevalence of cardiovascular disease. ecg tracings were prepared from 198 women and 178 men aged 40-60. only 45% of the tracings were completely normal. q/qs abnormalities were found in 4.7% of tracings, left axis deviation in 4% tall r wave in 37%, st depression in 3.9% of men and 14.1% of women...

Background: Cardiac manifestations that occur in a majority of patients with organophosphate (OP) poisoning may range from innocuous electrocardiographic manifestations, such as sinus tachycardia, to life-threatening complications, including cardiogenic pulmonary edema and myocardial necrosis. In this study, we evaluated the various electrocardiographic manifestations in patients with OP pois...

in hungary, ecg is a keystone of routine athletic screening. its significance is based on simplicity, quickness and high informative value as well as the fact that appearance of pathological ecg signs can precede the formation of structural heart diseases. during screening of healthy athletes, we studied the incidence of athletic ecg changes and pathological ecg abnormalities. methods: we pe...

OBJECTIVE This study aims to determine whether baseline electrocardiography (ECG) abnormalities, the appearance of new ECG abnormalities, or other clinical characteristics are associated with increased rates of progression to chronic Keshan disease (KD) among patients with latent KD. METHODS Four hundred and fourteen new latent KD patients from a monitored population in China were diagnosed a...

ventricular arrhythmias are one of the most important causes of annual deaths in the world, which may lead to sudden cardiac deaths. accurate and early diagnosis of ventricular arrhythmias in heart diseases is essential for preventing mortality in cardiac patients. ventricular activity on the electrocardiogram (ecg) signal is in the interval from the beginning of qrs complex to t wave end. vari...
