ENDOCAVITARY ELECTROPHYSIOLOGICAL STUDY

The endocavitary electrophysiological study is an examination that studies the electrical system of the heart, the origin and conduction of the electrical impulses that allow the heart to contract and perform its function. When the electrical system of the heart presents anomalies, cardiac arrhythmias occur, which can manifest themselves with a heartbeat that is too fast or too slow or irregular, causing symptoms such as palpitations, difficulty breathing, dizziness, loss of consciousness. Cardiac arrhythmias can be caused by different mechanisms: the presence of an anomalous electrical pathway or an electrical circuit or a focus that discharges high-frequency impulses or disorganized impulses that cause the heart to contract rapidly and irregularly or by a malfunction of the structures from which the "normal" or sinus electrical impulses originate, such as the sinus node or the atrioventricular node. Arrhythmias can also be generated in different locations of the heart.

The endocavitary electrophysiological study allows the precise diagnosis of the mechanism and location of the arrhythmia and represents the basis for a correct treatment.
