Background: Coronary Artery Disease (CAD) is one of the major causes of mortality in most countries. Electrocardiography (ECG) and myocardial perfusion imaging (MPI) are non-invasive disgnostic tests for CAD. Finding a relationship between abnormal findings in the baseline ECG and MPI findings can be helpful in better diagnosis of CAD. Materials and Methods: The present study examined ECG of pa...
Introduction: Electrocardiogram (ECG) is a method to measure the electrical activity of the heart which is performed by placing electrodes on the surface of the body. Physicians use observation tools to detect and diagnose heart diseases, the same is performed on ECG signals by cardiologists. In particular, heart diseases are recognized by examining the graphic representation of heart signals w...
the aim of this study was to define the electrocardiogram (ecg) changes following the moderate to severe co intoxication in rats, and also evaluating the effect of erythropoietin (epo) on observed cardiac disturbances. the growing literature on erythropoietin effect on cardiac ischemia led us to question its effect on cardiotoxicity due to the carbon monoxide poisoning. wistar rats were exposed...
سیگنال الکتروکاردیوگرام (ecg) معمول ترین روش غیرتهاجمی برای بررسی سلامتی قلب یا تشخیص احتمالی بیماری های قلبی است. مطالعات نشان می دهد سیگنال ecg یک ساختار خطی ساده ندارد بلکه دارای مؤلفه های غیرخطی است. در این مقاله سیگنال ecg به عنوان یک سری زمانی در نظر گرفته شده است و شاخص های غیرخطی آشوبی مانند بزرگ ترین نمای لیاپانوف ( ) و بعد همبستگی (d2) از سیگنال ecg برای افراد سالم و بیمار استخراج می ...
Cardiac arrhythmia refers to any abnormal electrical activity in the heart that causes irregular heartbeat. Under clinical settings, the arrhythmias can be monitored non-invasively using the electrocardiogram (ECG). Although reliable, the method is still prone to error due to its dependence on visual interpretation. Further, ECG data is enormous in dimension and increases as the data sampling r...
With the technological advancements in field of tele-health monitoring, it is now possible to gather huge amount electro-physiological signals such as electrocardiogram (ECG). It therefore necessary develop models/algorithms that are capable analysing these massive data real-time. This paper proposes a deep learning model for real-time segmentation heartbeats. The proposed DENS-ECG algorithm, c...
the aim of this study was to evaluate the effect of ecg, pgf2α, and combination of ecg and pgf2α early postpartum on reproductive performance in high producing dairy cows. three hundred sixty eight postpartal holstein dairy cows were divided in 4 groups. cows in groups 1 and 2 received 500 iu ecg on day 8 ± 2 and cows in groups 3 and 4 received saline. cows in groups 1 and 3 received injections...
