Conditions We Treat: Syncope
Syncope (fainting) occurs when not enough blood reaches a person's brain and they pass out. Pre-syncope means feeling dizzy or lightheaded but not actually fainting. While syncope is often not dangerous, it can also be the first and only warning before sudden cardiac death. Therefore, people with syncope should be evaluated by a knowledgeable physician.
Syncope: What You Need to Know
- Syncope has many possible causes, including cardiovascular conditions such as cardiac arrhythmias.
- To diagnose the underlying cause, your doctor may recommend a noninvasive evaluation with an ECG, echocardiogram, Holter or event monitor, or tilt table test. In some cases an electrophysiology study is required.
- Treatment options vary based on the precise cause of syncope. For some patients treatment includes education and increased salt and fluid intake. For others, treatment may be catheter ablation or placement of a pacemaker or implantable defibrillator.
