The electrophysiological examination is a form of heart catheter examination, which is carried out for patients with cardiac arrhythmia. The electrophysiological examination is used for analysing cardiac arrhythmias as well as for treatment decision and control.
While the patient is continuously monitored by ECG and blood pressure measuring device, the arrhythmia is interrupted using two electrodes. After that, individual drugs are injected, which are able to trigger or stop the racing heart. As an alternative and under local anaesthetic and X-ray monitoring, a catheter in the femoral vein is used in order to trigger a cardiac arrhythmia by means of a catheter ablation. After the examination is finished, the electrode catheters are removed and a compression dressing is applied. This dressing remains in place for a period between four and twelve hours.
Possible complications are injuries of the blood vessels as well as bleeding, infection, bruising and the triggering of cardiac arrhythmia.
