2024年10月10日 · A review of ECG features of left ventricular hypertrophy (LVH), including voltage and non-voltage criteria

The most common causes of left ventricular hypertrophy are aortic stenosis, aortic regurgitation, hypertension, cardiomyopathy and coarctation of the aorta. There are several ECG indexes, which generally have high diagnostic specificity but low sensitivity.

2009年2月19日 · Left ventricular hypertrophy commonly occurs in heart diseases that also cause intraventricular conduction defects or delays (IVCDs). As both LVH and IVCDs alter QRS patterns, the existence of an IVCD may impact the accuracy of ECG criteria for LVH.

2025年3月17日 · Hypertrophic cardiomyopathy is a genetic disease that causes left ventricular hypertrophy, especially septal hypertrophy, in young patients without pressure overload. LVH often progresses to severe and serious complications such as left ventricular outflow tract obstructions, ischemic heart disease or arrhythmias.

Current electrocardiographic (ECG) criteria for the diagnosis of left ventricular hypertrophy (LVH) have low sensitivity. The goal of this study was to test a new method to improve the diagnostic performance of the electrocardiogram. The study was divided into 2 groups, a test and a validation cohort.

2025年2月14日 · The electrocardiogram (ECG) is a useful but imperfect tool for detecting LVH. The utility of the ECG relates to its being relatively inexpensive and widely available. The limitations of the ECG relate to its moderate sensitivity or specificity depending upon which of the many proposed sets of diagnostic criteria are applied [1,2].

Left ventricular hypertrophy can be diagnosed on ECG with good specificity. When the myocardium is hypertrophied, there is a larger mass of myocardium for electrical activation to...

2022年1月31日 · ECG of Left ventricular hypertrophy (LVH) Tall R waves in leads I, aVL, V5 and V6, with deep S waves in leads V1, V2 and V3. The Cornell criteria involve measuring the S wave in lead V3 and the R wave in lead aVL.

2023年11月24日 · Zhao et al. recognized ECG-LVH, defined by Sokolow-Lyon criteria, as a strong predictor for stroke in hypertensive patients, especially those younger than 65 years. ECG-LVH was strictly related to an increased risk of stroke after adjustment of both baseline SBP and mean SBP over the treatment period (Zhao et al., 2020).
