Heart failure ( HF ), also known as congestive heart failure ( CHF ), is a syndrome caused by an impairment in the heart's ability to fill with and pump blood. Although symptoms vary based on which side of the heart is affected, HF typically presents with shortness of breath, excessive fatigue, and bilateral leg swelling. [ 3]
Left axis deviation. The hexaxial reference system is a diagram that is used to determine the heart's electrical axis in the frontal plane. In electrocardiography, left axis deviation (LAD) is a condition wherein the mean electrical axis of ventricular contraction of the heart lies in a frontal plane direction between −30° and −90°.
First-degree atrioventricular block (AV block) is a disease of the electrical conduction system of the heart in which electrical impulses conduct from the cardiac atria to the ventricles through the atrioventricular node (AV node) more slowly than normal. First degree AV block does not generally cause any symptoms, but may progress to more ...
Cardiology. Acute decompensated heart failure ( ADHF) is a sudden worsening of the signs and symptoms of heart failure, which typically includes difficulty breathing ( dyspnea ), leg or feet swelling, and fatigue. [1] ADHF is a common and potentially serious cause of acute respiratory distress. The condition is caused by severe congestion of ...
Echocardiography, cardiovascular MRI [ 1] Differential diagnosis. Athletic heart syndrome. Left ventricular hypertrophy ( LVH) is thickening of the heart muscle of the left ventricle of the heart, that is, left-sided ventricular hypertrophy and resulting increased left ventricular mass .
58260-1. Cardiac markers are biomarkers measured to evaluate heart function. They can be useful in the early prediction or diagnosis of disease. [ 1] Although they are often discussed in the context of myocardial infarction, other conditions can lead to an elevation in cardiac marker level. [ 2][ 3] Cardiac markers are used for the diagnosis ...
E/A ratio. The E/A ratio is a marker of the function of the left ventricle of the heart. It represents the ratio of peak velocity blood flow from left ventricular relaxation in early diastole (the E wave) to peak velocity flow in late diastole caused by atrial contraction (the A wave). [ 1] It is calculated using Doppler echocardiography, an ...
Diagnose myocardial infarct via physical exam and EKG (plus blood test) A diagnosis of myocardial infarction is created by integrating the history of the presenting illness and physical examination with electrocardiogram findings and cardiac markers ( blood tests for heart muscle cell damage ). [1] [2] A coronary angiogram allows visualization ...
