Generally, the EKG of individuals with syncope is normal. However, EKG may be remarkable for an arrhythmia. The arrhythmia may be seen on the EKG include sinus bradycardia <40 beats/min or repetitive sinoatrial blocks or sinus pauses > 3s, Mobitz II 2nd or 3rd-degree atrioventricular block, alternating left and right bundle branch block, rapid paroxysmal supraventricular tachycardia, ventricular tachycardia, and pacemaker malfunction with cardiac pauses. | |||

Overview
Generally, the EKG of individuals with syncope is normal. However, EKG may be remarkable for an arrhythmia. The arrhythmia may be seen on the EKG include sinus bradycardia <40 beats/min or repetitive sinoatrial blocks or sinus pauses > 3s, Mobitz II 2nd or 3rd-degree atrioventricular block, alternating left and right bundle branch block, rapid paroxysmal supraventricular tachycardia, ventricular tachycardia, and pacemaker malfunction with cardiac pauses.
Electrocardiogram
Generally, the EKG of individuals with syncope is normal. However, EKG may be remarkable for an arrhythmia. The following arrhythmia may be seen on the EKG:[1]
- Sinus bradycardia <40 beats/min or repetitive sinoatrial blocks or sinus pauses > 3s
- Mobitz II 2nd or 3rd-degree atrioventricular block
- Alternating left and right bundle branch block
- Rapid paroxysmal supraventricular tachycardia
- Ventricular tachycardia
- Pacemaker malfunction with cardiac pauses
Example
Shown below is an EKG of an elderly man with syncope.
2006 ACC/AHA/ESC Guidelines for Management of Patients With Ventricular Arrhythmias and the Prevention of Sudden Cardiac Death (DO NOT EDIT) [2]
Guidelines
Electrophysiological Testing in Patients With Syncope
| 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)" |
