Sudden cardiac death- MedGen UID:
- 38841
- •Concept ID:
- C0085298
- •
- Pathologic Function
The heart suddenly and unexpectedly stops beating resulting in death within a short time period (generally within 1 h of symptom onset).
Cardiac arrest- MedGen UID:
- 5456
- •Concept ID:
- C0018790
- •
- Finding
An abrupt loss of heart function.
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.
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.
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).
Premature ventricular contraction- MedGen UID:
- 56236
- •Concept ID:
- C0151636
- •
- Disease or Syndrome
Premature ventricular contractions (PVC) or ventricular extrasystoles are premature contractions of the heart that arise in response to an impulse in the ventricles rather than the normal impulse from the sinoatrial (SA) node.
Prolonged QRS complex- MedGen UID:
- 489828
- •Concept ID:
- C0235475
- •
- Finding
Increased time for the complex comprised of the Q wave, R wave, and S wave as measured by the electrocardiogram (EKG).. In adults, normal values are 0.06 - 0.10 sec.
Fibrofatty replacement of right ventricular myocardium- MedGen UID:
- 369873
- •Concept ID:
- C1968863
- •
- Pathologic Function
Replacement of the myocardium of the right ventricular free wall by fat and fibrous tissue.
Right ventricular cardiomyopathy- MedGen UID:
- 384481
- •Concept ID:
- C2063326
- •
- Disease or Syndrome
Right ventricular dysfunction (global or regional) with functional and morphological right ventricular abnormalities, with or without left ventricular disease.
Dilatation of the ventricular cavity- MedGen UID:
- 1393082
- •Concept ID:
- C4476545
- •
- Anatomical Abnormality
A localized outpouching of ventricular cavity that is generally associated with dyskinesia and paradoxical expansion during systole.
Epsilon wave- MedGen UID:
- 1815063
- •Concept ID:
- C5706157
- •
- Finding
An electric signal of depolarization observed between the end of the QRS complex and the beginning of the T wave.
Dyspnea- MedGen UID:
- 3938
- •Concept ID:
- C0013404
- •
- Sign or Symptom
Difficult or labored breathing. Dyspnea is a subjective feeling only the patient can rate, e.g., on a Borg scale.
- Abnormality of the cardiovascular system
- Abnormality of the respiratory system
- Constitutional symptom
