An Intelligent High Accuracy & hybrid Identification for Heart diseases Diagnosis

Contemporary methods diagnose congenital heart diseases (CHD) with high accuracy but postnatal diagnostics of vascular rings (VR) remains difficult. From 2004 to 2017 in our Center were performed 7740 primary fetal echocardiograms and more than 65,000 echocardiograms for children. From 2004 to 2017 18589 operations of congenital heart disease were performed, of them 95 (0,51%) were VR surgery. Of all patients treated with VR 21 (22,1%) had prenatal diagnosis, 74 (77,9%) – had postnatal. Since 2011 during postnatal and prenatal echocardiography, we introduced a new protocol with necessary views for VR visualization. Thanks to the use it increased the number of operations on the VR. Surgical treatment of VR has excellent results with low surgical risk. For the successful VR surgical treatment is necessary CT to perform for required to clarify the anatomy of the VR and the trachea. Prenatal and postnatal Echo can help of VR detection in a group of asymptomatic patients.

Abstract: The electrical activity of the heart is test with an electrocardiogram (ECG). The fundamental information for the taking decision about various types of heart diseases identified by electrocardiogram. There have been numerous attempts over decades to extract the characteristics of the heartbeat through ECG records with high accuracy and efficiency using a variety of strategies and techniques. In this paper a novel scheme is acquainted, the problem is solved by isolated time space using q-lag unbiased finite impulse response (UFIR), then the received time changing of optimal average horizon for the shape of the ECG signal. A complete statistical analysis is furnished by normalized histogram and statistical classifiers, P wave features extraction based on the detected fiducial points is deliberated. In this concept by utilizing QRS detection, morphological top-bottom hat transformation and notch filters is ameliorated PSNR and latency constraints, furnishes high accuracy and reduced elapsed time. Keywords: Electrocardiogram (ECG) denoising, unbiased finite impulse response (UFIR) filtering, P wave feature extraction, normalized histogram, QRS complex detection.

High Voltage Electron

The high voltage electron microscope has many advantageous features in comparison with the ordinary electron microscope. They are a higher penetrating efficiency of the electron, low chromatic aberration, high accuracy of the selected area diffraction and so on. Thus, the high voltage electron microscope becomes an indispensable instrument for the metallurgical, polymer and biological specimen studies. The application of the instrument involves today not only basic research but routine survey in the various fields. Particularly for the latter purpose, the performance, maintenance and reliability of the microscope should be same as those of commercial ones. The authors completed a 500 kV electron microscope in 1964 and a 1,000 kV one in 1966 taking these points into consideration. The construction of our 1,000 kV electron microscope is described below.

This paper describes morphological and cytochemistry changes of endomyocardial biopsy in 94 patients. The samples of myoicardium were taken from 32 patients with dilated cardiomyopathy, and sdudied with light and electron microscop. The cytochemical studies in some of these patients were performed at histological and ultrastructure level. This paper also reported the result of myocardial biopsy in 33 patients with serious dysrythmia.The result of this controlled study indicates that morphological assessment in both cardiomyopathy and congenital or rheumatic heart diseases showed no special changes. In patients of dilated cardiomyopathy, the decreased activity of myosin ATPase was secondary to cardial failure. The change of succinate dehydrogenase (SDHase) was not significant with light microscopy. But ultrastructural localization of SDHase activity is valuable. Its activity was found to be localized in endomembrane and ridge of the mitochondria, the activity of this enzyme was decrease, normal, or increase. SDHase activity was more intense in cardial myocytes well-functioning, or ultrastructurally well preserved hearts.

Positive Effect

While the use of vinegar to fi ght against infections and other crucial conditions dates back to Hippocrates, recent research has found that vinegar consumption has a positive effect on biomarkers for diabetes, cancer, and heart diseases. Different types of vinegar have been used in the world during different time periods. Vinegar is produced by a fermentation process. Foods with a high content of carbohydrates are a good source of vinegar. Review of the results of different studies performed on vinegar components reveals that the daily use of these components has a healthy impact on the physiological and chemical structure of the human body. During the era of Hippocrates, people used vinegar as a medicine to treat wounds, which means that vinegar is one of the ancient foods used as folk medicine. The purpose of the current review paper is to provide a detailed summary of the outcome of previous studies emphasizing the role of vinegar in treatment of different diseases both in acute and chronic conditions, its in vivo mechanism and the active role of different bacteria.
