#VitalStream #Labtech_Holter Prognostic Value and Limits of Heart Rate and QT—Corrected in A Large Population by Paolo Giovanardi 1,2,*ORCID,Cecilia Vernia3,Giuseppe Spadafora 1,ORCID1 Cardiology Service, Department of Primary Care, Health Authority and Services of Modena, Via del Pozzo 71, 41125 Modena, Italy Hearts 2024, 5(2), 225-235; Accepted: 24 May 2024 / Published: 27 May 2024 Abstract Background: The study aimed to compare the prognostic importance of the heart rate (HR) and QT—corrected (QTc) according to Fridericia, Framingham, and Bazett with respect to all-cause mortality in a large non-selected population. Methods: The analysis of digital electrocardiograms archived from 2008 to 2022 in the metropolitan area of Modena, Italy, was carried out. The population under study was divided into three groups based on age, and survival analysis was performed. Results: 131,627 patients were enrolled and, during the follow-up (mean 1641.4 days), all-cause mortality was 8.9%. Both HR and QTc were associated with mortality. All-cause mortality significantly increased with HR values greater than 81 BPM and QTc values greater than 440 msec in young subjects and 455 msec in old subjects (values of the 75th percentiles/optimal operating point). A Cox analysis confirmed the better prognostic value of Bazett’s QTc and HR in the whole population and in the three age-groups. Conclusion: Bazett’s method performed better than the others, but, unexpectedly, the HR had the same or an even better correlation with all-cause mortality. Since the HR is simple and readily available, its evaluation should be improved. However, QTC and HR values are difficult to define, causing many confounding factors, and further population studies are required #Caretaker type4 #メディカルテクニカ　#連続非観血式　#ストロークボリューム　#動脈硬化指標　研究用 #vitalStream #waveletalgorithm #Labtech_Holter
