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.
Cardiac arrest- MedGen UID:
- 5456
- •Concept ID:
- C0018790
- •
- Finding
An abrupt loss of heart function.
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.
Palpitations- MedGen UID:
- 14579
- •Concept ID:
- C0030252
- •
- Finding
A sensation that the heart is pounding or racing, which is a non-specific sign but may be a manifestation of arrhythmia.
Pulmonary embolism- MedGen UID:
- 11027
- •Concept ID:
- C0034065
- •
- Pathologic Function
An embolus (that is, an abnormal particle circulating in the blood) located in the pulmonary artery and thereby blocking blood circulation to the lung. Usually the embolus is a blood clot that has developed in an extremity (for instance, a deep venous thrombosis), detached, and traveled through the circulation before becoming trapped in the pulmonary artery.
Syncope- MedGen UID:
- 21443
- •Concept ID:
- C0039070
- •
- Sign or Symptom
Syncope is a syndrome in which loss of consciousness is of relatively sudden onset, temporary (usually less than 1 to 2 minutes), self-terminating, and of usually rapid recovery. Syncope leads to a generalized weakness of muscles with loss of postural tone, inability to stand upright, and loss of consciousness. Once the patient is in a horizontal position, blood flow to the brain is no longer hindered by gravitation and consciousness is regained. Unconsciousness usually lasts for seconds to minutes. Headache and drowsiness (which usually follow seizures) do not follow a syncopal attack. Syncope results from a sudden impairment of brain metabolism usually due to a reduction in cerebral blood flow.
Torsades de pointes- MedGen UID:
- 21214
- •Concept ID:
- C0040479
- •
- Disease or Syndrome
A type of ventricular tachycardia characterized by polymorphioc QRS complexes that change in amplitue and cycle length, and thus have the appearance of oscillating around the baseline in the EKG.
Prolonged QTc interval- MedGen UID:
- 294666
- •Concept ID:
- C1560305
- •
- Pathologic Function
A longer than normal interval (corrected for heart rate) between the Q and T waves in the heart's cycle. Prolonged QTc can cause premature action potentials during late phase depolarizations thereby leading to ventricular arrhythmias and ventricular fibrillations.
Permanent atrial fibrillation- MedGen UID:
- 750308
- •Concept ID:
- C2586056
- •
- Pathologic Function
Atrial fibrillation (AF) that cannot be successfully terminated by cardioversion, and longstanding (more than 1 year) AF, where cardioversion is not indicated or has not been attempted, is termed permanent.
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
