ECG strain provides powerful insights into the status of the LV myocardium in populations at risk of LV decompensation: it appears to be a specific marker of mid-wall left ventricular myocardial fibrosis and predictive of . When LVH is caused by a pathological condition, we often see the "strain" pattern, which is ST depression and T wave inversion in leads with upright QRS complexes (the lateral leads). A reciprocal ST elevation can .In this challenge, we will focus on the distortions created by the Left Ventricular Hypertrophy (LVH) pattern. Please answer the following Q&A regarding the LVH Pattern: Common distortions to the 12-lead ECG, secondary to LVH (Left .
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 . The ECG strain pattern of lateral ST depression and T-wave inversion is a marker for left ventricular hypertrophy (LVH) and adverse prognosis in population studies. However, whether ECG strain is an . The most common ECG dilemmas one encounters is to differentiate between the ST segment depression and T wave inversion due to LVH from that of primary ischemia. Very often , the entity is misdiagnosed . The implication can be serious , and adding further complexity is exercise stress testing is alos prone for errors in. 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. . we often see the "strain" pattern, which is ST depression and T wave inversion in leads with upright QRS complexes (the lateral leads). A .
In hypertension, left ventricular (LV) ECG strain is a powerful predictor of myocardial infarction (MI) and cardiovascular death. 3 It is also a significant independent predictor for the development of, and death from, congestive cardiac failure. 4 Furthermore, the development of ECG strain in the context of anti-hypertensive therapy is .
ECG Pearl. There are no universally accepted criteria for diagnosing RVH in the presence of RBBB; the standard voltage criteria do not apply. However, the presence of incomplete / complete RBBB with a tall R wave in V1, right axis deviation of +110° or more and supporting criteria (such as RV strain pattern or P pulmonale) would be considered . Background—ECG left ventricular hypertrophy with strain is associated with an adverse prognosis in aortic stenosis. We investigated the mechanisms and outcomes associated with ECG strain. Methods and Results—One hundred and two patients (age, 70 years [range, 63–75 years]; male, 66%; aortic valve area, 0.9 cm2 [range, 0.7–1.2 cm2]) underwent ECG, .
LVH with strain pattern can sometimes be seen in long standing severe aortic regurgitation, usually with associated left ventricular hypertrophy and systolic dysfunction. The sensitivity of LVH strain pattern on ECG as a measure of LVH has ranged from 3.8% to 50% in various reports [1]. The same data quoted specificity ranging from 89.8% to 100%. Repolarization abnormalities can cause ST segment depressions and T-wave inversions in the lateral leads, known as the left ventricular strain pattern. Let’s also refresh ourselves with the STEMI criteria [1]: New ST Elevation at the J point in two contiguous leads of >1 mm in all leads other than V2-V3; For Leads V2-V3, the following cutoffs .

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 (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. Moreover, the strain pattern could also reflect underlying coronary heart disease (CHD), a relationship that could in part explain the clinical consequences of this ECG finding beyond those directly attributable to high left ventricular (LV) mass 3, 4, 8, 10. However, the independent relationship of ECG strain to LV mass, as opposed to its .
This 92-year-old patient was diagnosed with left bundle branch block on ECG, and left ventricular hypertrophy on echocardiogram. The two conditions are very often seen together, in fact, a majority of LBBB patients .
Other associated features may include:. Left atrial enlargement (“P mitrale”) — left ventricular diastolic dysfunction may lead to compensatory left atrial hyertrophy; Signs of WPW (short PR, delta wave) — ECG features of .V4-V6 precordial leads may show ST depression & T wave inversions known as the LV Strain pattern; Romhilt-Estes Criteria. Diagnostic ≥ 5 points and probable ≥ 4 points) ECG Criteria: . Romhilt DW and Estes EH Jr. A point-score system for the ECG diagnosis of left ventricular hypertrophy. Am Heart J 1968 Jun; 75(6) 752-8. lmid:4231231 . The following are key points to remember about this article on assessing left ventricular (LV) systolic function: from ejection fraction (EF) to strain analysis: LVEF, defined as the ratio of LV stroke volume to LV end-diastolic volume, is one of the most frequently measured variables in clinical practice.Left Ventricular Hypertrophy With Strain Pattern (Example 3)
Introduction. The classic strain pattern of ST depression and T-wave inversion on the rest electrocardiogram (ECG) is a well-recognized marker of the presence of anatomic left ventricular hypertrophy (LVH) .This abnormality of repolarization has been associated with an adverse prognosis in a variety of clinical populations and implicated as the strongest marker of .28%. Seventy-six patients showed ECG pattern of LV hypertrophy without strain whereas 227 showed ECG pattern of LV hypertrophy with strain. Patients with LV hypertrophy with strain pattern showed more frequently severe AS. During a mean follow-up of 7.2 ± 4.8 years (10,258 patient-years), 545 (37.9%) patients died.The ECG criteria for diagnosing right or left ventricular hypertrophy are very insensitive (i.e., sensitivity ~50%, which means that ~50% of patients with ventricular hypertrophy cannot be recognized by ECG criteria). This ECG shows voltage criteria for LVH (deep S waves V1-V3 and tall R waves V4 - V6). There are many criteria in use for determining LVH, but probably the most commonly used is the Sokolow-Lyon criteria.. This criteria says that if the voltage of the S wave in V1 PLUS the tallest R wave of V4, V5, and V6 equals 35 mm or more, the criteria are sufficient for LVH.
The classic strain pattern of ST depression and T-wave inversion on the ECG is a well-recognized marker of the presence and severity of anatomic left ventricular hypertrophy (LVH) 1–8 that improves ECG detection of structural hypertrophy when incorporated into scores that include standard voltage criteria. 2,6 ECG strain has been associated with adverse . 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 . Therefore, because of these ECG limitations, LVH is most reliably identified on imaging with either echocardiography or cardiac magnetic resonance imaging.
The presence of ECG LV hypertrophy and strain pattern in AS patients has been independently associated with cardiovascular death. 3, 5–7 Analysis from the SALTIRE study with 1,254 patient-years of follow-up, showed the independent prognostic value of the ECG strain pattern for predicting aortic valve replacement or cardiovascular death. 3 .
The relation of ECG strain pattern to LV diastolic function is less well documented. Recently, Palmieri et al. reported no difference in diastolic function parameters in hypertensive subjects with or without strain pattern. 26 A similar finding was also reported from a study in native Africans. 24 Some of the possible explanations include: 26 .
