Atrial conduction disease(CCDD)

MedGen UID:
863722
Concept ID:
C4015285
Disease or Syndrome
Synonym: Cardiac conduction disease with or without dilated cardiomyopathy
Modes of inheritance:
Autosomal dominant inheritance
MedGen UID:
141047
Concept ID:
C0443147
Intellectual Product
Source: Orphanet
A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in heterozygotes. In the context of medical genetics, an autosomal dominant disorder is caused when a single copy of the mutant allele is present. Males and females are affected equally, and can both transmit the disorder with a risk of 50% for each child of inheriting the mutant allele.

Definition

A rare genetic cardiac disease characterized by variably expressed atrial tachyarrhythmia (such as atrial flutter, paroxysmal or chronic atrial fibrillation, ectopic atrial tachycardia, or multifocal atrial tachycardia), infra-Hisian conduction system disease, and vulnerability to dilated cardiomyopathy. Age of onset ranges between childhood and adulthood. [from ORDO]

Clinical features

From HPO
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.
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.
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.
Paroxysmal supraventricular tachycardia
MedGen UID:
18314
Concept ID:
C0030590
Disease or Syndrome
An episodic form of supraventricular tachycardia with abrupt onset and termination.
Tachycardia
MedGen UID:
21453
Concept ID:
C0039231
Finding
A rapid heartrate that exceeds the range of the normal resting heartrate for age.
Sinus bradycardia
MedGen UID:
39316
Concept ID:
C0085610
Pathologic Function
Bradycardia related to a mean resting sinus rate of less than 50 beats per minute.
Atrial arrhythmia
MedGen UID:
39317
Concept ID:
C0085611
Pathologic Function
A type of supraventricular tachycardia in which the atria are the principal site of electrophysiologic disturbance.
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.
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.
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.
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.
