The aV limb leads in the diagnosis of ventricular strain

American Heart Journal, 1950
Abstract The amplitude of each deflection in Leads aV R , aV L , and aV F has been measured in 100 normal electrocardiograms and in 137 tracings indicative of left, right, or combined ventricular strain, as judged by the standard limb and precordial leads.

Afterload Dependence of Right Ventricular Myocardial Strain

Journal of the American Society of Echocardiography, 2017
Right ventricular (RV) free wall strain (RVFWS) is a feasible method for quantitation and follow-up of RV function and may have benefits over traditional markers such as fractional area change. However, like all ejection phase parameters, RVFWS is difficult to assess in the presence of changing afterload.

Electrocardiographic Strain Pattern in Children With Left Ventricular Hypertrophy: A Marker of Ventricular Dysfunction

Pediatric Cardiology, 2010
The objective of this study was to assess the relation between strain pattern on electrocardiogram (ECG-strain) and echocardiographic indices of left ventricular (LV) structure and function in children with LV hypertrophy (LVH). ECG-strain is a marker of LVH and is associated with adverse cardiovascular prognosis in adults.

Left atrial, ventricular and atrio-ventricular strain in patients with subclinical heart dysfunction

The International Journal of Cardiovascular Imaging, 2018
Arterial hypertension (AH) and diabetes mellitus (DM) are the most common causes of heart deterioration because of their high prevalence in the population. The aim of this study was to evaluate peak left atrial (LA), longitudinal strain (PALS), left ventricular (LV), longitudinal  strain (LS) and global atrial-ventricular strain (GAVS), by speckle ...

Quantitative estimation of ventricular strain in the limb leads

American Heart Journal, 1954
Abstract 1.1. A new index for the quantitative estimation of ventricular strain is described. This index combines in a single expression the two most constant quantitative changes of ventricular strain pattern, i.e., those of the QRS complex and T wave in the following form: [(R1−S1)−2T1]+[(S3−R3)+2T3]. 2.2.
