BACKGROUND: The existing electrocardiogram(ECG)measurement strongly depends on medical professionals and inefficient high-intensity,or relies on automatic identification method which is not accurately enough.Thus,this is difficult to meet high-speed testing,accurate results and ease application for common people.OBJECTIVE: To develop a new method that was simple and efficient to apply and very easy to learn.METHODS: Algorithms were programmed and test software was developed by delphi7.0.ECG was drawn on screen.The apex,the starting point and the ending point as well as the J-point of each ECG wave were clicked by mouse or stylus.Then the wave parameters and an initial diagnosis could be quickly obtained by test software.RESULTS AND CONCLUSION: The parameters of ECG waveform such as wave height,wave time,PR interval,ST segment,QT segment,PP/RR time,cardiac electrical axis and so on could be accurately measured,and heart rate,heart rhythm and the deflection of cardiac electrical axis could be diagnosed correctly.The method was simple to learn and easy to imply,and it was also efficient,quick and accurate.Thus,it could greatly improve the efficiency of measurement and analysis for specialists,and could meet application requirements of general medicals and ordinary people.

OBJECTIVE: To analyze the clinical effect of different canalith repositioning maneuver in the treatment of the apogeotropic nystagmus of horizontal semicircular canal benign paroxysmal positional vertigo (apogeotropic HSC-BPPV). METHOD: Forty patients of apogeotropic HSC-BPPV colleted from March 2014 to May 2015 were divided into two groups, each group had 20 cases. The control group was repositioned with the Gufoni maneuver before the Barbecue maneuver, the research group with the improved Nuti maneuver. RESULT: The success rate of the research group was not lower than that of the control group, which hadn't statistical (P > 0.05). And after the Barbecue maneuver, all patients have been recovered. CONCLUSION Comparing with the Gufoni maneuver, the improved Nuti maneuver designed by us, had the same success rate to treat apogeotropic HSC-BPPV, and is easier to learn,with more compliance,more comfort and more repeatability.

Objective To explore the influencing factors of pulmonary infection in patient with stroke, in order to provide the basis for clinical rehabilitation nursing. Methods A total of 237 patients with stroke who were treated in hospitalsfrom January 2015 to December 2015, were enrolled in the study. To analysis the effect of several influencing factors such as age, sex, consciousnessdisorders, pulmonary diseases, swallowing disorder and the activities of daily living(ADL). Results Of the 237 patients, 66 were complicated with pulmonary infection, and the incidence rate of pulmonary infection was 27.8％. Thepulmonary infection in patients with stroke was associated with swallowing disorder, hypertension, pulmonarydiseases, albumin,stomach pipe retaining, proton pump, swallowing disorder, long bedridden and ADL. These results had significantly deference (P<0.05). The logistic regression analysis showed that the independent risk factors for sex, consciousnessdisorders, pulmonarydiseases, swallowing disorder and ADL. Conclusions The influencing factors were existed in pulmonary infection in patients with stroke. The independent risk factors for pulmonary infection in patient with stroke included sex, consciousnessdisorders, pulmonarydiseases, swallowing disorder and ADL. In the above some factors, nurse should be providingrehabilitation nursing measure to reduce the incidence rate of pulmonary infection.
