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).
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.
Hypertrophic cardiomyopathy- MedGen UID:
- 2881
- •Concept ID:
- C0007194
- •
- Disease or Syndrome
Hypertrophic cardiomyopathy (HCM) is defined by the presence of increased ventricular wall thickness or mass in the absence of loading conditions (hypertension, valve disease) sufficient to cause the observed abnormality.
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.
Left bundle branch block- MedGen UID:
- 7286
- •Concept ID:
- C0023211
- •
- Disease or Syndrome
A conduction block of the left branch of the bundle of His. This manifests as a generalized disturbance of QRS morphology on EKG.
Mitral regurgitation- MedGen UID:
- 7670
- •Concept ID:
- C0026266
- •
- Disease or Syndrome
An abnormality of the mitral valve characterized by insufficiency or incompetence of the mitral valve resulting in retrograde leaking of blood through the mitral valve upon ventricular contraction.
Stroke disorder- MedGen UID:
- 52522
- •Concept ID:
- C0038454
- •
- Disease or Syndrome
Sudden impairment of blood flow to a part of the brain due to occlusion or rupture of an artery to the brain.
Left atrial enlargement- MedGen UID:
- 536845
- •Concept ID:
- C0238705
- •
- Finding
Increase in size of the left atrium.
Left anterior fascicular block- MedGen UID:
- 75547
- •Concept ID:
- C0264912
- •
- Disease or Syndrome
Conduction block in the anterior division of the left bundle branch of the bundle of His.
Right atrial enlargement- MedGen UID:
- 677114
- •Concept ID:
- C0748427
- •
- Disease or Syndrome
Increase in size of the right atrium.
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.
- Abnormality of the cardiovascular system
- Constitutional symptom
