Atrial fibrillation- MedGen UID:
- 445
- •Concept ID:
- C0004238
- •
- Finding
An atrial arrhythmia characterized by disorganized atrial activity without discrete P waves on the surface EKG, but instead by an undulating baseline or more sharply circumscribed atrial deflections of varying amplitude an frequency ranging from 350 to 600 per minute.
Atrioventricular block- MedGen UID:
- 13956
- •Concept ID:
- C0004245
- •
- Disease or Syndrome
Delayed or lack of conduction of atrial depolarizations through the atrioventricular node to the ventricles.
Primary dilated cardiomyopathy- MedGen UID:
- 2880
- •Concept ID:
- C0007193
- •
- Disease or Syndrome
Familial dilated cardiomyopathy is a genetic form of heart disease. It occurs when heart (cardiac) muscle becomes thin and weakened in at least one chamber of the heart, causing the open area of the chamber to become enlarged (dilated). As a result, the heart is unable to pump blood as efficiently as usual. To compensate, the heart attempts to increase the amount of blood being pumped through the heart, leading to further thinning and weakening of the cardiac muscle. Over time, this condition results in heart failure.\n\nIt usually takes many years for symptoms of familial dilated cardiomyopathy to cause health problems. They typically begin in mid-adulthood, but can occur at any time from infancy to late adulthood. Signs and symptoms of familial dilated cardiomyopathy can include an irregular heartbeat (arrhythmia), shortness of breath (dyspnea), extreme tiredness (fatigue), fainting episodes (syncope), and swelling of the legs and feet. In some cases, the first sign of the disorder is sudden cardiac death. The severity of the condition varies among affected individuals, even in members of the same family.
Congestive heart failure- MedGen UID:
- 9169
- •Concept ID:
- C0018802
- •
- Disease or Syndrome
The presence of an abnormality of cardiac function that is responsible for the failure of the heart to pump blood at a rate that is commensurate with the needs of the tissues or a state in which abnormally elevated filling pressures are required for the heart to do so. Heart failure is frequently related to a defect in myocardial contraction.
Premature atrial contractions- MedGen UID:
- 19455
- •Concept ID:
- C0033036
- •
- Disease or Syndrome
A type of cardiac arrhythmia with premature atrial contractions or beats caused by signals originating from ectopic atrial sites.
Ventricular tachycardia- MedGen UID:
- 12068
- •Concept ID:
- C0042514
- •
- Finding
A tachycardia originating in the ventricles characterized by rapid heart rate (over 100 beats per minute) and broad QRS complexes (over 120 ms).
Reduced left ventricular ejection fraction- MedGen UID:
- 868398
- •Concept ID:
- C4022792
- •
- Finding
A diminution of the volumetric fraction of blood pumped out of the ventricle with each cardiac cycle.
- Abnormality of the cardiovascular system
