2024年10月10日 · Left ventricular hypertrophy (LVH): Markedly increased LV voltages: huge precordial R and S waves that overlap with the adjacent leads (SV2 + RV6 >> 35 mm). R-wave peak time > 50 ms in V5-6 with associated QRS broadening. LV strain pattern with ST depression and T-wave inversions in I, aVL and V5-6. ST elevation in V1-3. Prominent U waves in V1-3.

Left ventricular hypertrophy (LVH) 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 …

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.

2009年2月19日 · In the presence of ECG criteria for LVH, the presence of prominent S waves in V 5 or V 6, right axis deviation, unusually tall biphasic R/S complexes in several leads, and signs of right atrial abnormality are useful signs that RVH may also be present. 57,58

2023年8月8日 · Electrocardiography (ECG) is the least expensive and most readily available test for the diagnosis of LVH. While its specificity is relatively high, its low sensitivity makes the clinical utility somewhat limited. Various criteria for LVH by ECG have been suggested over the years.

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 ].

2015年11月8日 · How is LVH diagnosed on an ECG. Most trained operators will spot signs of LVH relatively quickly on a ECG recording as it will be common that precordial ventricular tracings will overlap one another requiring a reduction in gain settings. However, the Sokolow Lyon criteria is correct method of choice.

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).
