What is left ventricular strain?

Left ventricular (LV) systolic wall strain is a new candidate for prognostic indicator of hypertensive heart failure. It remains unclear how underlying transmural structural remodeling corresponds to LV wall systolic deformation as hypertensive hypertrophy progresses.

What is the criteria for LVH?

Left Ventricular Hypertrophy ECG Criteria If the sum is greater than 28 millimeters in males or greater than 20 mm in females, LVH is present. Modified Cornell Criteria: Examine the R wave in aVL. If the R wave is greater than 12 mm in amplitude, LVH is present.

What is Sokolow Lyon criteria?

The Sokolow-Lyon voltage criterion-based LVH was defined as a composite of amplitudes (SV1 or V2 + RV5 or V6) ≥35 mm, and the Cornell voltage criterion-based LVH was defined as RaVL+ SV3 ≥28 mm for men (2,3).

How do you read left ventricular hypertrophy on ECG?

The most commonly used ECG criteria to diagnosed left ventricular hypertrophy (LVH) is below: Cornell criteria: Add the R wave in aVL and the S wave in V3. If the sum is > 28 mm in males or > 20 mm in females, then LVH is present.

What causes left ventricular strain?

The most common cause of left ventricular hypertrophy is high blood pressure (hypertension). High blood pressure makes your heart work harder than normal. The extra work it takes to pump blood can cause the muscle in the left ventricle walls to get larger and thicker.

What is a strain on the heart?

In echocardiography, the term ‘strain’ is used to describe local shortening, thickening and lengthening of the myocardium as a measure of regional LV function. The term originates from the field of continuum mechanics and is used to describe a general 3D deformation of a small cube during a short time interval.

What is mild 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.

What is Cornell voltage?

Background: ECG-diagnosed left ventricular hypertrophy (LVH), the Cornell voltage (CV: ≥2.8mV in males and ≥2.0mV in females) or Cornell product (CP: ≥244.0mV×ms), were selected in Western countries for their ability to diagnose anatomical LVH.

How is left ventricular dysfunction diagnosed?

To examine the extent of damage due to left ventricular dysfunction, cardiologists prescribe the following tests:

  1. An array of blood tests: To test abnormal levels of certain blood components.
  2. Echocardiogram: Sound waves are used to obtain video data of your heart’s condition.
  3. Electrocardiogram: Measures electrical signals.

Is left ventricular hypertrophy normal?

An enlarged or thickened heart — a condition doctors call left-ventricular (LV) hypertrophy — can lead to heart failure. It also may double the risk of dementia and cognitive impairment. “Hypertrophy is not normal.
