Before the onset of AMI, some patients may have the clinical symptoms (such as palpitations, shortness of breath, chest discomfort, and/or precordial pain) of coronary heart disease. It results in interruption of blood flow and myocardial ischemia, and long-term ischemia will lead to myocardial ischemic injury ( 1). Accepted for publication Sep 16, 2020.Īcute myocardial infarction (AMI) is the acute thrombotic occlusion of coronary arteries caused by the rupture of atherosclerotic plaque in the coronary arteries. Keywords: Acute myocardial infarction Elderly patient Ventricular fibrillation Dynamic electrocardiogram Heart rate variability Predictive value The area under the ROC curves (AUC)and cut-off values of SDNN, SDANN, rMSSD and PNN50% were (0.773, 0.761, 0.800, 0.819) and (135.675, 106.850, 33.570, 14.080), respectively.Ĭonclusions: HRV of DCG is of certain predictive value for VF in the elderly with AMI, which is expected to be an auxiliary diagnosis method of VF. Results: The ratio of Killip at grade II-III, activity of creatine kinase-MB (CK-MB), standard deviation of all R-R intervals (SDNN), the standard deviation of the R–R intervals (SDANN), root-mean-square of the successive differences of normal RR intervals (rMSSD) and percentage of NN50 in the total number of NN intervals PNN50 (PNN50%)]in VF group were higher than those in AMI group (P<0.05). The predictive value of HRV of DCG in VF of elderly AMI patients was evaluated by receiver operating characteristic (ROC) curves. The basic data of patients were compared. They were divided into VF group and simple AMI group (AMI group). Methods: A total of 122 elderly AMI patients were enrolled as the research objects. The article is aimed at exploring the predictive value of heart rate variability (HRV) of dynamic electrocardiogram (DCG) in VF of elderly AMI patients. Identifying arrhythmia as early as possible is of great significance in improving prognosis of AMI patients. Policy of Dealing with Allegations of Research Misconductīackground: Ventricular fibrillation (VF) is the main cause of sudden death in Acute myocardial infarction (AMI) patients.Policy of Screening for Plagiarism Process.One at a time, for a one-of-a-kind person. We personally handcraft each design from start to finish. Our stethoscope name plates are the most diverse and personal that you can find online. We wanted to offer something new and something truly special. NOTE: If you have a thick cardiology stethoscope or are not sure what type of stethoscope you have, please choose the yoke tag instead as it will fit all stethoscopes. TUBE tag comes in black, blue, green, pink, red, white and yellow and is adjustable to 3 different diameters to fit on a variety of different stethoscopes. YOKE tag comes in black or gray and was designed to fit perfectly on the top yoke of most stethoscopes or between the yokes on double yoke stethoscopes with thicker cardiology tubing. Only the 1 inch is set into your choice of plain, cap, rope or bling bezel setting. BUTTON SIZE/SETTING: Choose from the 1-1/2 inch or 1 inch size. A touch of flair here, a splash of color there – it’s little things like this that let professionals seem more approachable, break down clinical “walls”, and put patients at ease in a stressful situation. Making Meaningful Connections - We create heartfelt, customizable designs that help foster warmer interpersonal relationships and build an instant rapport with patients and families. Perfect for nurses, general physicians, cardiologists, nursing students, vets & vet techs and other hands-on healthcare workers in the field. Personalize and easily identify your stethoscope with our one-of-a-kind stethoscope name tag designs. This stethoscope id tag design will be personalized with your name, initial, monogram (first, last, middle initials) and occupation title (optional and not included unless requested).
