At autopsy, a pathologist can diagnose a myocardial infarction based on anatomopathological findings. A chest radiograph and routine blood tests may indicate complications or precipitating causes and are often performed upon arrival to an emergency department. New regional wall motion abnormalities on an echocardiogram are also suggestive of a ...
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 ...
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 multiple ...
Atrial tachycardia is a type of heart rhythm problem in which the heart 's electrical impulse comes from an ectopic pacemaker (that is, an abnormally located cardiac pacemaker) in the upper chambers ( atria) of the heart, rather than from the sinoatrial node, the normal origin of the heart's electrical activity .
Tachycardia-induced cardiomyopathy (TIC) is a disease where prolonged tachycardia (a fast heart rate) or arrhythmia (an irregular heart rhythm) causes an impairment of the myocardium (heart muscle), which can result in heart failure. [ 1][ 5] People with TIC may have symptoms associated with heart failure (e.g. shortness of breath or ankle ...
Ischemic Cardiomyopathy. Ischemic cardiomyopathy is a type of cardiomyopathy caused by a narrowing of the coronary arteries which supply blood to the heart. [ 4] Typically, patients with ischemic cardiomyopathy have a history of acute myocardial infarction, [ 5] however, it may occur in patients with coronary artery disease, but without a past ...
Vectorcardiography. Normal vectorcardiogram. ICD-9-CM. 89.53. MeSH. D014672. [ edit on Wikidata] Vectorcardiography ( VCG) is a method of recording the magnitude and direction of the electrical forces that are generated by the heart by means of a continuous series of vectors that form curving lines around a central point. [ 1]
Cardiac function curve. A cardiac function curve is a graph showing the relationship between right atrial pressure (x-axis) and cardiac output (y-axis). [citation needed] Superimposition of the cardiac function curve and venous return curve is used in one hemodynamic model. [ 1]
