“…Recommended criteria include Sokolow-Lyon index >3.5 mV, Cornell's voltage criteria >2436 mm-sec, and RomhiltEstes score 5 or above. Some authors also showed that R wave voltage in aVL >1.1 mV correlates well with left ventricular mass index (35). The selection of appropriate ECG criteria for LVH detection should include the age factor according to a recent study (36,37).…”

Left ventricular hypertrophy (LVH) is a structural remodeling of the heart developing as a response to volume and/or pressure overload. Previous studies have shown that hypertension is not an independent factor in the development of LVH and occurrence does not depend on the length and severity of hypertension, but the role played by other comorbidities such as triglycerides, age, gender, genetics, insulin resistance, obesity, physical inactivity, increased salt intake and chronic stress. LVH develops through three phases: adaptive, compensatory, and pathological phase. Contractile dysfunction is reversible in the first two phases and irreversible in the third. According to the Framingham study, LVH develops in 15-20% of patients with mild arterial hypertension, and in 50% of patients with severe hypertension. The pathophysiology of LVH includes hypertrophy of cardiomyocytes, interstitial and perivascular fibrosis, coronary microangiopathy and macroangiopathy. Individuals with LVH have 2-4 times higher risk of having adverse CV events compared to patients without LVH. (Anadolu Kardiyol Derg 2014; 14: 389-95)

“…In response, the "JECG LVH Working Group" was formed with Ljuba Bacharova as chair, and they have published statements in 2010 11 and 2011. 12 The second statement outlines the main difference between the traditional simple concepts of relating ECG changes to left ventricular mass (LVM) in patients with LVH, and proposes an alternative model that considers an important factor-"hypertrophic electrical remodeling."…”

“…The aim of this review is to provide an overview of the complex biology of left ventricular hypertrophy with an eye toward enhancing our understanding of its ECG manifestations. 3,4 Hypertrophic growth of the cardiac myocyte Whereas recent work has revealed that a small fraction of cells within the ventricle are capable of re-entering the cell cycle, 5-7 the vast majority of cardiac myocytes are postmitotic and hence do not retain the ability to divide. Rather, they respond to stress by growing, shrinking, or dying.…”

Hypertrophic growth of the heart occurs in many clinical scenarios, and it confers substantially increased risk of untoward sequelae. Among them, transition to ventricular dilation, wall thinning, contractile dysfunction, and a clinical syndrome of heart failure is paramount. Left ventricular hypertrophy (LVH) is typically diagnosed by either electrocardiography or echocardiography. However, these two means of assessing hypertrophic transformation of the left ventricle can sometimes disagree. At one level, this may not be surprising as the two methodologies are based on entirely divergent signals: electrical potential between two places on the surface of the skin and ultrasound energy reflected from the ventricle itself. Echocardiography is an effective means of assessing ventricular mass, which is a cardinal feature of LVH. Importantly, however, LVH is characterized by a wide range of remodeling events beyond simple increases in muscle mass. Electrocardiographic changes in LVH are reflective of the electrophysiological aspects of hypertrophic transformation. Here, I present an overview of the complex biology of left ventricular hypertrophy with an eye toward enhancing our understanding of its ECG manifestations.
