What does strain in ECG indicate?

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.

What is the prognostic implication of a left ventricular strain pattern on ECG?

Background: 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.

Is heart strain serious?

If left untreated, it can lead to some serious complications, including heart failure. If you have any symptoms of a heart problem, including chest pain, shortness of breath, or swelling in your legs, contact your doctor as soon as possible.

What causes heart strain?

Right heart strain can be caused by pulmonary hypertension, pulmonary embolism (or PE, which itself can cause pulmonary hypertension), RV infarction (a heart attack affecting the RV), chronic lung disease (such as pulmonary fibrosis), pulmonic stenosis, bronchospasm, and pneumothorax.

What causes ventricular strain?

Is LVH common in athletes?

Physiological left ventricular hypertrophy (athlete’s heart) or hypertrophic cardiomyopathy. A small minority of highly trained athletes exhibit substantial LVH, with values between 13 and 16 mm, which overlaps with values observed in 10–15\% of patients with morphologically mild HCM.

What is normal global longitudinal strain?

Normal ranges of global left ventricular longitudinal strain. A meta-analysis: 2,597 subjects from 24 studies. Reported normal values of GLS varied from -15.9\% to -22.1\% (mean, -19.7\%; 95\% CI, -20.4\% to -18.9\%).

What is the normal longitudinal strain?

Normal values of longitudinal LV deformation are between -20 to -25 \%. Strain rate: rate of myocardial deformation in time. Units are expressed in number/second or \%/second. Diastolic myocardial deformation can be assessed more clearly in this way.

What does global longitudinal strain mean?

Global longitudinal strain (GLS) is abnormal among patients with cardiac amyloid , sometimes despite preserved left ventricular ejection fraction ( LVEF ). Cardiac amyloid has a characteristic strain pattern with apical sparing. Hypertrophic cardiomyopathy (HCM).

What is left ventricular strain?

Left ventricular hypertrophy Left ventricular hypertrophy is a thickening of the wall of the heart’s main pumping chamber. This thickening may result in elevation of pressure within the heart and sometimes poor pumping action. The most common cause is high blood pressure.
