All subjects underwent gated myocardial perfusion scintigraphy and standard Echocardiography.<strong> Results: </strong>About 84% of cases were diagnosed with any types of cardiac disorders by Echocardiography, whereas through scintigraphy, 61% of patients were detected cardiac disorders. The age stratification did not impact the prevalence of cardiac disorders detected by them. Scintigraphy showed a higher detection rate (59%), while only 29% of cases were detected with IHD by eco-cardiograph. <strong>Conclusions:</strong> In conclusion, both techniques, namely standard Echocardiography, and myocardial scintigraphy, are useful in the evaluation and detection of cardiac disorders in patients having any type of cardiac problems. Both investigations showed a differential pattern in cardiac disorders diagnosis with a particular focus on IHD. Gender differences and age stratification also contributed to this differential pattern of diagnosis. <strong>Trial Registration:</strong> The research doesn’t include experiments in humans or animals. It is a retrospective study for data record review as an observational study, so no trial registration is required.展开更多

Perfect standards and technical specifications in the field of electrical safety and interference protection are an important basis for ensuring the safety of electrified railways. Both China and Japan have very perfect standard systems in the field of electromagnetic protection, and there are many similarities and differences in their standard construction. These differences cover many aspects such as technical research, management system, operation and maintenance, etc. Therefore, based on the standards, specifications and technical regulations of the two countries, it is hoped to study the similarities and differences of grounding, EMF (electromagnetic radiation and environmental assessment), lightning protection and other aspects in the field of electromagnetic protection of electrified railway between the two countries, and to promote the improvement and progress of the relevant standard systems.展开更多
