Two experiments were performed to determine the effectiveness of different progestogens contained in intravaginal devices, different doses of eCG and subsequent hCG treatment on the reproductive performance of estrus-induced mature Lori ewes. In the first experiment, 88 ewes were allocated into two groups, and were treated with either fluorogestone acetate (FGA) sponges or Controlled Internal D...

سیگنال الکتروکاردیوگرام (ECG) معمول‌ترین روش غیرتهاجمی برای بررسی سلامتی قلب یا تشخیص احتمالی بیماری‌های قلبی است. مطالعات نشان می‌دهد سیگنال ECG یک ساختار خطی ساده ندارد بلکه دارای مؤلفه‌های غیرخطی است. در این مقاله سیگنال ECG به عنوان یک سری زمانی در نظر گرفته شده است و شاخص‌های غیرخطی آشوبی مانند بزرگ‌ترین نمای لیاپانوف ( ) و بعد همبستگی (D2) از سیگنال ECG برای افراد سالم و بیمار ...

Even with the development of more advanced technology of ECG, there are still problems on interference to ECG signals. Many attempts have been made to detect and eliminate the source of noises and artifacts from the original ECG signals. Several studies have been done to observe and study the EMI effect, however, most of them only focus on the EMI effect of mobile phone during ECG acquisition. ...

iometric systems are mostly used as person identification or verification systems. In the last few decades, the Electrocardiogram (ECG) has been introduced as a most powerful biometric tool for personal/individual identification. ECG has unique cardiac feature to each individual which motivated its use in various identification systems. Recent developments have also shown that person identifica...

An Electrocardiogram signals change their statistical property over time and ECG signals are highly non-stationary signals. Growing of embedded technology has provided powerful tools to analysis of ECG. ECG is advanced recording method of bioelectric signal which is originated in the heart and it provides valuable information about the activity of human heart. Different types of features of the...

This paper presents a novel maximum margin clustering method with immune evolution (IEMMC) for automatic diagnosis of electrocardiogram (ECG) arrhythmias. This diagnostic system consists of signal processing, feature extraction, and the IEMMC algorithm for clustering of ECG arrhythmias. First, raw ECG signal is processed by an adaptive ECG filter based on wavelet transforms, and waveform of the...

Given renewed interest in the primary prevention of cardiovascular disease, we comprehensively reviewed the utility of the electrocardiogram (ECG) for screening considering the seminal epidemiologic studies. It appears that conventional risk factors relate to long-term risk, while ECG abnormalities are better predictors of short-term risk. For individual ECG abnormalities as well as for pooled ...

Electrocardiogram (ECG)-based detection of left ventricular systolic dysfunction (LVSD) has poor specificity and positive predictive value, even when including major ECG abnormalities, such as left bundle branch block (LBBB) within the criteria for diagnosis. Although machine-read ECG algorithms do not provide information on LVSD, advanced ECG (A-ECG), using multiparameter scores, has superior ...
