Impairment of conduction in heart excitation often applied specifically to atrioventricular heart block.Reversibility depends on the degree of structural or functional defects. Heart blocks can be classified by the duration, frequency, or completeness of conduction block. Impaired conduction of cardiac impulse that can occur anywhere along the conduction pathway, such as between the sinoatrial node and the right atrium (sa block) or between atria and ventricles (av block).An impairment of transmission of the cardiac electrical impulse along the fibers normally responsible impulse propagation.Typically patients develop an initial pallor, followed by facial flush during recovery. It is caused by a sudden decrease of the cardiac output that results from a sudden cardiac dysrhythmia.
An episode of sudden and transient loss of consciousness sometimes associated with seizures.Abnormality in rhythm of heartbeat, including rate, regularity, and/or sequence of activation abnormalities.A disorder characterized by pathological irregularities in the cardiac conduction system.A disorder affecting the conduction system that sends electrical signals in the myocardium.In some cases, the syncope attacks are transient and in others cases repetitive and persistent. When the cardiac output becomes too low, the patient faints (syncope). A condition of fainting spells caused by heart block, often an atrioventricular block, that leads to bradycardia and drop in cardiac output.Cardiac dysrhythmia (heart rhythm disorder).transient cerebral ischemic attacks and related syndromes ( G45.-).systemic connective tissue disorders ( M30-M36).symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified ( R00- R94).When considering the heart is a pump and if everything else is functioning properly. It is the same as the range for normal sinus rhythm.
The criteria is the same with the only difference being the heart rate range is 60 100 bpm.
