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 .
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 ...
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 ...
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]
Multifocal (or multiform) atrial tachycardia (MAT) is an abnormal heart rhythm, [ 2] specifically a type of supraventricular tachycardia, that is particularly common in older people and is associated with exacerbations of chronic obstructive pulmonary disease (COPD). Normally, the heart rate is controlled by a cluster of cells called the ...
Echocardiography, also known as cardiac ultrasound, is the use of ultrasound to examine the heart. It is a type of medical imaging, using standard ultrasound or Doppler ultrasound. [ 1] The visual image formed using this technique is called an echocardiogram, a cardiac echo, or simply an echo . Echocardiography is routinely used in the ...
The Framingham Risk Score is a sex-specific algorithm used to estimate the 10-year cardiovascular risk of an individual. The Framingham Risk Score was first developed based on data obtained from the Framingham Heart Study, to estimate the 10-year risk of developing coronary heart disease. [ 1] In order to assess the 10-year cardiovascular ...
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 ...
