Sick sinus syndrome |
"An abnormality involving the generation of the action potential by the sinus node and is characterized by an atrial rate inappropriate for physiological requirements. Manifestations include severe sinus bradycardia, sinus pauses or arrest, sinus node exit block, chronic atrial tachyarrhythmias, alternating periods of atrial bradyarrhythmias and tachyarrhythmias, and inappropriate responses of heart rate during exercise or stress."

First degree atrioventricular block |
"Delay of conduction through the atrioventricular node, which is manifested as prolongation of the PR interval in the electrocardiogram (EKG). All atrial impulses reach the ventricles." [DDD:dbrown, HPO:probinson] |
The conduction of the cardiac impulse through the atrioventricular node is manifested in the EKG by the PR interval, which is normally less that 200 milliseconds in adults. Normal values are age-dependent in children, but normal values are less that 160 milliseconds in young children. |

Second degree atrioventricular block |
"An intermittent atrioventricular block with failure of some atrial impulses to conduct to the ventricles, i.e., some but not all atrial impulses are conducted through the atrioventricular node and trigger ventricular contraction." [DDD:dbrown, HPO:probinson] |

Mobitz I atrioventricular block |
"Progressive PR interval prolongation with the subsequent occurrence of a single nonconducted P wave that results in a pause. The pause that follows the nonconducted impulse is less than fully compensatory (less than the sum of two normal sinus intervals)." [DDD:dbrown, HPO:probinson] |
Mobitz I atrioventricular block is associated with a normal QRS duration. |

Mobitz II atrioventricular block |
"A type of second degree atrioventricular (AV) block characterized by sudden failure to conduct an impulse through the AV node without a preceding change in the PR interval." [DDD:dbrown, HPO:probinson] |
Mobitz I atrioventricular block is usually associated with a prolonged QRS duration. |

Atrioventricular dissociation |
"Atrioventricular (AV) dissociation is present if the atria and the ventricles are under the control of two separate pacemakers. AV dissociation can occur in the absence of a primary AV conduction disturbance." [HPO:probinson] |
Atrioventricular dissociation can develop in response to severe sinus bradycardia with AV junctional rhythm or with an enhanced lower (junctional or ventricular) pacemaker that competes with the normal sinus rhythm and exceeds it. |

Bundle branch block |
"Block of conduction of electrical impulses along the Bundle of His or along one of its bundle branches." [DDD:dbrown, HPO:probinson] |
The Bundle of His conducts the electrical impulse from the atrioventricular node into the ventricles. THe Bundle of His divides into right and left bundle branches. A universal feature of a bundle branch block is a prolongation of the time required for depolarization of a portion of the ventricles, reflected in an abnormality of the QRS complex. |
