Strain, strain rate and speckle tracking: Myocardial deformation

…Figure 1A 2C. The orientation of myocardial muscle fibers results in longitudinal, radial and circumferential shortening (contraction). Traditional methods for investigating left ventricular function — e…

Heart Failure With Preserved Ejection Fraction: Diagnosis and Treatment

…occur because elevated left sided filling pressures are transmitted to the pulmonary circulation. Persistent pulmonary vascular disease can lead to right ventricular strain and dysfunction…

Right ventricular strain: definition, causes, echocardiography

…strain When assessing the right half of the heart, it is important to familiarize yourself with the principles of hemodynamics and conditions prevailing on the…

ECG parameters

…hypertrophy +90° to +180° Right axis deviation — right ventricular strain, lateral infarction, left posterior fascicular block −90° to ±180° Extreme axis deviation Amplitude criteria Criterion…

Cardiovascular Risk in Women: Sex-Specific Factors

…than men after approximately 65 years of age. Hypertension related left ventricular hypertrophy, concentric remodelling, reduced longitudinal strain and heart failure with preserved ejection fraction…

Pulmonary embolism: quick reference for risk stratification and treatment

…< 100 mmHg and a saturation < 90 per cent. An sPESI of 0 indicates low risk. Anticoagulation A DOAC is the first choice in…

Ventricular tachycardia (VT): ECG criteria, causes, classification, treatment

…disorders , congenital heart disease and catecholamine induced ventricular tachycardia . The vast majority of patients with ventricular tachycardia either have coronary artery disease (ischemic heart disease)…

Assessing left ventricular systolic function

…the apex during systole. Mitral annulus velocity correlates well with ejection fraction, stroke volume and is thus a measure of systolic function. Strain and strain…

Congenital heart disease & GUCH (Grown Up Congenital Heart disease)

…connection and the relationship of the great arteries (segmental analysis). Ventricular function is evaluated using ejection fraction, fractional shortening, stroke volume, and myocardial thickness. Strain…

ECG in left ventricular hypertrophy (LVH): criteria and implications

…vector of the left ventricle is enhanced in LVH, which results in large R waves in left sided leads (V5, V6, aVL and I) and…
