2Improved scoring system for the electrocardiographic diagnosis of left ventricular hypertrophy显示文摘BACKGROUND Left ventricular hypertrophy(LVH) is a common manifestation of cardiovascular disease and a risk factor for cardiovascular morbidity and mortality, but available methods for its electrocardiographic(ECG) diagnosis have limited accuracy.AIM To investigate findings associated with LVH on ECG and developed an improved system for the diagnosis of LVH.METHODS A cohort study comparing ECG data acquired within 30 days of transthoracic echocardiography(TTE) was performed. Multivariate regression analysis identified ECG findings associated with increased LV mass and mass index. A scoring system was derived and performance compared to established criteria for LVH.RESULTS Data from 5486 outpatients with TTEs and corresponding ECGs were included in the derivation cohort, 333(6.1%) of whom had LVH by TTE. In the primary regression analysis, findings associated with LVH were amplitudes of Q in V3, R in V6, S in V3, T in V6, P' in V1, P in V6, as well as R and T-axis discordance, R peak time in V6, QRS duration, weight, height, sex, and age. From this we derived a score consisting of 5 criteria, and validated it in an independent cohort of 910 patients. With a threshold of 1.5 points, sensitivity and specificity were67.9% and 81.4%, and 62.5% and 83.2% in the derivation and validation cohorts,respectively. With a threshold of 2 points, sensitivity and specificity were 42.3% and 93.0%, and 37.5% and 93.4% in these cohorts.CONCLUSIONS This score had superior sensitivity for detection of LVH by ECG while making a modest sacrifice in specificity compared to conventional criteria.Eric D Braunstein Lori B Croft Jonathan L Halperin Steve L Liao 2019World Journal of Cardiology2019,11,3:2
