Left Ventricular Function

Echocardiography Left ventricular function and its echocardiographic assessment Cardiac function depends on a large number of parameters, including atrial function, valvular function, and ventricular function…

Aortic regurgitation

…in the left ventricle and left atrium. Chronic aortic regurgitation leads to dilatation and hypertrophy of the left ventricle. Cardiac remodeling Ventricular dilatation and hypertrophy…

Anticoagulation Strategies in Atrial Fibrillation

…the left atrial appendage (LAA). The LAA is a highly trabeculated, windsock like embryonic remnant that exhibits uniquely low flow velocities during the loss of…

Pulmonary Embolism (PE)

…ventricle, which is counteracted by dilatation of the ventricle. Dilatation of the right ventricle results in reduced intraventricular pressure and thereby reduced myoardial load. Pulmonary…

Tricuspid regurgitation (TR/TI)

…Rheumatic heart disease. Dilatation of the right ventricle. Dilatation of the right atrium. Pulmonary hypertension. Left to right shunt. Right ventricular dysfunction due to pressure…

The QRS complex: ECG features of the Q-wave, R-wave, S-wave & duration

…activation of the right ventricle does not come to expression , because it is drowned by the many times larger vector generated by the left ventricle…

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

…a patient on digoxin treatment 1 ECG signs of left atrial enlargement 3 Left axis deviation 2 QRS duration ≥90 milliseconds 1 Prolonged R wave…

Atrial and ventricular enlargement: hypertrophy and dilatation on ECG

…the articles on left ventricular enlargement, right ventricular enlargement and atrial enlargement. Below follows a discussion on the principles and differences of dilatation and hypertrophy…

Left atrial enlargement (P mitrale) & right atrial enlargement (P pulmonale) on ECG

…The duration of the P wave will exceed 120 milliseconds in lead II. Biatrial abnormality/enlargement Biatrial abnormality implies that the ECG indicates both left…

Left bundle branch block (LBBB): ECG criteria, causes, management

…the left ventricle partially or entirely outside the specialized conduction system. This slower conduction results in a prolonged QRS duration. The defining features of LBBB…
