BackgroundBoth ECG strain pattern and QRS measured left ventricular (LV) hypertrophy criteria are associated with LV hypertrophy and have been used for risk stratification. However, the independent predictive value of ECG strain in apparently healthy individuals in predicting mortality and adverse cardiovascular events is unclear. Methods and ResultsMESA . The classic left ventricular (LV) strain pattern of ST segment depression and T-wave inversion on the left precordial leads of the standard resting ECG is a well-known marker of the presence of anatomic LV hypertrophy (LVH). 1–6 Furthermore, the occurrence of this electrocardiographic abnormality of ventricular repolarization has been associated with a .V4-V6 precordial leads may show ST depression & T wave inversions known as the LV Strain pattern; Romhilt-Estes Criteria.

It appears that our patient meets LVH voltage criteria. With LVH, it is common to see a strain pattern, where there are ST Depression and T Wave inversions in the left sided leads [2]. Is this patient having LVH with strain or is it a true STEMI? Armstrong et al introduced a flow chart to help identify a STEMI in patients with LVH [5]: Electrocardiographic left ventricular hypertrophy (LVH) has many faces with countless features. Beyond the classic measures of LVH, including QRS voltage and duration, the left ventricular (LV) strain pattern is an element whereby characteristic R-ST depression is followed by a concave ST segment that ends in an asymmetrically inverted T wave.Electrocardiographic left ventricular hypertrophy with strain pattern has been documented as a marker for left ventricular hypertrophy. Its presence on the ECG of hypertensive patients is associated with a poor prognosis. This review was undertaken . Left ventricular hypertrophy (LVH) is a condition in which there is an increase in left ventricular mass, either due to an increase in wall thickness or due to left ventricular cavity enlargement, or both. Most commonly, the left ventricular wall thickening occurs in response to pressure overload, and chamber dilatation occurs in response to the volume overload.[1]
Left Ventricular Hypertrophy With Strain. Submitted by Dawn on Thu, 12/12/2013 - 10:38. This ECG is from a man with left ventricular hypertrophy. LVH causes taller-than-normal QRS complexes in leads oriented toward the left side of the heart, such as Leads I, II, aVL, V4, V5, and V6. Leads on the opposite side, such as V1, V2, and V3, will have . Left Ventricular Hypertrophy With Strain. Submitted by Dawn on Thu, 12/12/2013 - 10:38. This ECG is from a man with left ventricular hypertrophy. LVH causes taller-than-normal QRS complexes in leads oriented toward the left side of the heart, such as Leads I, II, aVL, V4, V5, and V6. Leads on the opposite side, such as V1, V2, and V3, will have .Left ventricular hypertrophy (LVH) is a well‐known risk factor for cardiovascular morbidity and mortality. 1, 2, 3 Early diagnosis is essential as regression of LVH is associated with a reduction in cardiovascular events. 4, 5, 6 Although several modalities are available for detection of LVH, ECG and echocardiography are most commonly used in . It is now appreciated that electrocardiographic LVH with ST-segment and T-wave abnormalities occurs in conditions that are not necessarily caused by increased hemodynamic work, as in patients with dilated or hypertrophic cardiomyopathies, and that lesser degrees of ST-T abnormalities than the “typical strain” pattern are associated with LVH .
Electrical remodeling of the left ventricle in the setting of hypertrophy causes ST elevation in leads V1-V3, as well as the "strain" pattern. In patients with LVH, this elevation in leads V1-V3 may mimic an anterior . Left Ventricular Hypertrophy (LVH) causes tall R waves in left sided and deep S waves in right sided leads. Always look for ‘strain’ pattern in left sided leads. . 3 points – for ST segment and T wave changes (‘typical .
Electrocardiographic left ventricular hypertrophy (LVH) has many faces with countless features. Beyond the classic measures of LVH, including QRS voltage and duration, the left ventricular (LV) strain pattern is an element whereby characteristic R-ST depression is followed by a concave ST segment that ends in an asymmetrically inverted T wave.

The classic strain pattern of ST depression and T-wave inversion on the ECG is a well recognized marker of the presence of anatomic left ventricular hypertrophy (LVH), 1–7 independent of the possible relationship of this repolarization abnormality to underlying coronary heart disease. 7 Indeed, the presence of even minimal degrees of ST depression in the lateral . Myocardial strain is a dimensionless variable representing the change in length between two points over the cardiac cycle, and can be quantified using echocardiography or CMR tissue tracking. Regional strain is less reproducible; whereas peak global strain is more consistent, supporting the use of global longitudinal strain (GLS) in clinical .
Left ventricular hypertrophy (LVH) is a major risk factor for cardiovascular disease, including sudden death. Antihypertensive therapy in patients with LVH results in lowering of blood pressure and drug-dependent reduction of LV mass. Complete reversal of LVH can be.
Left ventricular (LV) hypertrophy (LVH) is a frequent imaging finding in daily clinical practice, and its presence is associated with poor outcomes and ventricular arrhythmias. It is commonly detected in athletes, arterial hypertension, aortic stenosis, .
In electrocardiography, a strain pattern is a well-recognized marker for the presence of anatomic left ventricular hypertrophy (LVH) in the form of ST depression and T wave inversion on a resting ECG. [1] It is an abnormality of repolarization and it has been associated with an adverse prognosis in a variety heart disease patients. It has been important in refining the role of ECG . Introduction. The strain pattern in the 12‐lead ECG, defined as ST‐segment depression and T‐wave inversion, represents ventricular repolarization abnormalities.1 The mechanism underlying ECG strain is unclear, although it has been proposed as subendocardial ischemia.2, 3 ECG strain is associated with concentric left ventricular (LV) hypertrophy (LVH), . Prevalences of echocardiographic LVH, abnormal LV geometry and LV midwall function in patients with or without ECG strain are shown in Table 3. In this population selected on the basis of ECG LVH by Cornell product and/or Sokolow-Lyon voltage, strain was associated with a higher prevalence of LVH defined by LV mass/body surface area in patients with and .

Assessment of left ventricular systolic function has a central role in the evaluation of cardiac disease. Accurate assessment is essential to guide management and prognosis. Numerous echocardiographic techniques are used in the assessment, each with its own advantages and disadvantages. This review is based on a literature search of the PubMed, MEDLINE, .
