Bradycardia Nodular

Bradycardia is a slow heart rate. This may be due to various factors, for example, pathology in the sinus node or conduction system of the heart, as well as side effects of certain medications. Nodal block (bradycardia) can develop as a symptom of diseases of internal organs or systemic damage to the cardiovascular system. Therefore, cardiac nodal block requires a comprehensive and thorough examination of patients. Modern examination technologies, including the use of special instruments and computer techniques, make it possible to clarify the diagnosis.

Normally, impulses are generated in the sinus node, located on the posterior surface of the left atrium, and from there they are transmitted through special pathways to other parts of the myocardium. If the sinus node does not produce enough impulses to ensure the heart beats properly, quickly, a slow heart rate occurs. This condition is referred to as arrhythmia. Depending on where exactly the blockade of impulses occurred, different types of arrhythmias are distinguished. One of these disorders is nodal arrhythmia (syn. bradycardia).

Nodal block is classified depending on the location of the block. It is not difficult to identify this type of cardiac excitation disorder due to the fact that there is no need to use complex diagnostic measures.
