Abstract
Objective To investigate the influence factors of aVR QRs amplitude (ΣQRsaVR ) in patients with chronic heart failure and its Judgment in the prognosis of the patients. Methods 46 patients with chronic heart failure with the grade of NYHA Ⅱ-Ⅳ hospitalized in Mount Qianfo Affiliated Hospital of shandong University from February to October,2013 were selected as the subJects. This study conducted electrocardiography for the patients, measured QRs amplitude by stegel method and calculated the sum of aVR(ΣQRsaVR) and 6 limb leads(Σ6Lblds). This study also conducted colorful Doppler ultrasonocardiogram to assess left ventricular end-diastolic diameter( LVEDD) and left ventricular eJect fraction( LVEF) and drew patientsˊblood to determinate the level of natriuretic peptide ( BNP ) and creatinine ( Cr ). Multiple linear regression analysis was used for the influencing factors. Results ΣQRsaVR of the 46 patients was(0. 7 ± 0. 2) mm. Correlation analysis indicated that Σ6Lblds,body weight and LVEDD were key influence factors of ΣQRsaVR(r=0. 760,-0. 250,-0. 052,P<0. 05). Multiple linear regression showed thatΣ6Lblds,body weight and LVEDD were the influencing factors ofΣQRsaVR in chronic heart failure patients(P<0. 05),linear regression equation was y= -0. 012+0. 12 ×Σ6Lblds-0. 007 × BW-0. 006 × LVEDD. Conclusion Σ6Lblds,body weight and LVEDD are key influence factors of ΣQRsaVR. Dynastic observation ofΣQRsaVR can not only reflect change of body weight and evaluate patientsˊcondition but also be the clinical index of ventricular remodeling in patients with chronic heart failure.关键词
