Research On The Changes Of The QRS Wave Voltage Value Of AVR Lead In Patients With Cardiac Edema

Objective?Heart failure is the end stage of various heart diseases that lead toventricular filling and ejection ability damage, including myocardial injury andmyocardial structure and function change. Cardiac edema is one of right heart failuresymptoms. The edema that is sunk and symmetrical often occurs in the drooping partsof body. It causes jugular vein engorgement, hepatomegaly and so on, especiallycauses hydrothorax and bosom when the disease become serious. The aVR lead canprovides the information of the lead of V5to V6and the lead of I to II. The aVR leadseldom taken seriously by people in the past, but now, it has changed with the furtherresearch of electrocardiogram. Today my research aims at discussing the changes ofthe QRS wave voltage value of aVR lead and the BNP value in patients with cardiacedema. In order to enhance the clinical services, the research can not only improvethe accuracy of heart failure diagnosis and evaluate curative effect, but also canreduce the patient's medical treatment costs.Methods?The research separately measures the before and after treatment of patients'weight, BNP value and the QRS wave voltage value of aVR lead.Results?After effective treatment, the patients' weight loss(P<0.001); BNP value fall(P<0.001); the QRS wave voltage value of aVR lead rise(P<0.001).Conclusion?The extent of disease can be reflected by the changes of the patients'weight, the BNP value and the QRS wave voltage value of aVR lead. The patientswith cardiac edema can evaluate curative effect by monitoring the QRS wave voltagevalue of aVR lead.
