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.
Atrial flutter- MedGen UID:
- 13955
- •Concept ID:
- C0004239
- •
- Pathologic Function
A type of atrial arrhythmia characterized by atrial rates of between 240 and 400 beats per minute and some degree of atrioventricular node conduction block. Typically, the ventricular rate is half the atrial rate. In the EKG; atrial flutter waves are observed as sawtooth-like atrial activity. Pathophysiologically, atrial flutter is a form of atrial reentry in which there is a premature electrical impulse creates a self-propagating circuit.
Cardiac arrest- MedGen UID:
- 5456
- •Concept ID:
- C0018790
- •
- Finding
An abrupt loss of heart function.
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 fibrillation- MedGen UID:
- 21844
- •Concept ID:
- C0042510
- •
- Disease or Syndrome
Uncontrolled contractions of muscles fibers in the left ventricle not producing contraction of the left ventricle. Ventricular fibrillation usually begins with a ventricular premature contraction and a short run of rapid ventricular tachycardia degenerating into uncoordinating ventricular fibrillations.
Right bundle branch block- MedGen UID:
- 88445
- •Concept ID:
- C0085615
- •
- Disease or Syndrome
A conduction block of the right branch of the bundle of His. This manifests as a prolongation of the QRS complex (greater than 0.12 s) with delayed activation of the right ventricle and terminal delay on the EKG.
Supraventricular tachycardia with an accessory connection mediated pathway- MedGen UID:
- 866781
- •Concept ID:
- C4021132
- •
- Disease or Syndrome
Supraventricular tachycardia in which an accessory pathway connecting the atria and ventricles, apart from the AV node, participates as a necessary part of a reentrant mechanism.
- Abnormality of the cardiovascular system
- Constitutional symptom
