O estudo eletrofisiológico é um procedimento que tem como objetivo identificar e registrar a atividade elétrica do coração com o objetivo de verificar alterações no ritmo cardíaco. Assim, esse estudo é na maioria das vezes indicado pelo cardiologista quando a pessoa apresenta sinais e sintomas de alterações no coração que podem estar relacionados com a sua resposta aos estímulos elétricos.
- The electrophysiological study is usually indicated by the cardiologist to check if the cause of the signs and symptoms that the person presents is related to variations in the electrical stimuli that reach the heart and / or how this organ responds to electrical impulses.
- Therefore.
- This procedure may be indicated for:.
Thus, based on the result obtained by the electrophysiological study, the cardiologist may indicate the completion of new tests or the initiation of a treatment more oriented to the solution of the heart disturbance.
For electrophysiological study, fasting is recommended for at least 6 hours, in addition to routine blood tests and electrocardiogram. Before the procedure, the area where the catheter will be inserted, i.e. the femoral region, which corresponds to the groin region, is also removed. The procedure will last from 45 minutes to 1 hour and is performed in the operating room, as an incision is necessary to place the catheter to perform the electrophysiological study.
Because the procedure can cause pain and discomfort, it is usually performed under local and general anesthesia. The electrophysiological study is based on the introduction of certain catheters through the femoral vein, which is the vein located in the groin, which are placed, by means of a microchamber, in places in the heart linked to electrical impulses that reach the organ.
A partir do momento que os cateteres encontram-se nos locais apropriados para realização do exame, são gerados impulsos elétricos que são registrados pelo equipamento ao qual os cateteres estão acoplados. Assim, o médico pode avaliar o funcionamento do coração e verificar a presença de alterações.
The electrophysiological study with ablation corresponds to the procedure in which, at the same time as the study is performed, the treatment of the alteration is performed, which consists of an ablation. Ablation is the process of destroying or removing a faulty electrical signaling pathway related to heart failure.
Thus, ablation is performed immediately after the electrophysiological study and involves the introduction of a catheter, by the same route of entry to the body of the catheters used in the study, which reaches the heart. The tip of this catheter is made of metal and when it comes into contact with the heart tissue, it heats up and causes minor burns in the area that can remove the electrical signaling pathway.
After ablation, a new electrophysiological study is usually performed to check for a change in any other electrical cardiac signaling pathway during ablation.
