Overview
Electrocardiogram and Holter monitoring can help to analyze the electrical activities of the heart. They can supply information about the heart rhythm and indirectly, the heart size. It may help a doctor determine the relationship between syncope and any possible arrhythmias. Compared to a Holter monitor, electrophysiologic studies have a higher diagnostic yield, and it should be ordered for any patient with a suspected arrhythmia.

Electrophysiological Testing in Patients With Syncope Recommendations
| Class I |
| "1 EP testing is recommended in patients with syncope of unknown cause with impaired LV function or structural heart disease. (Level of Evidence: B) " |
| Class IIa |
| "1 EP testing can be useful in patients with syncope when bradyarrhythmias or tachyarrhythmias are suspected and in whom noninvasive diagnostic studies are not conclusive. (Level of Evidence: B)" |
