Fainting (syncope) can occur in a person’s life. In most cases, harmless circulation issues (vasovagal syncope) are the cause. However, should syncope repeatedly occur and/or injuries be sustained as a result, treatment should be sought. In the field of cardiology, either too slow or too fast a pulse is primarily suspected of being the cause. The appropriate tests in relation to this would be an ECG, stress ECG, long-term ECG, event recorder (externally or as an implant), tilt table test and the electrophysiological study. If too slow a pulse is discovered, usually a pacemaker will be implanted; should the pulse be too fast or heart palpitations often occur, an electrophysiological study and catheter ablation would be carried out.
