Syncope

What is syncope?

Syncope describes a temporary loss of consciousness — when you pass out or faint. There are different types of syncope:

Vasovagal syncope

Vasovagal syncope occurs when your heart isn’t pumping enough oxygen to your brain and your blood pressure is too low. Fainting may happen when you’re experiencing emotional distress or standing for long periods of time.

Postural syncope

Postural syncope occurs when a quick change in your body position causes a sudden drop in blood pressure. There is also a condition known as postural orthostatic tachycardia syndrome (POTS), a condition that causes a very rapid heartbeat when you stand up after sitting or lying down.

Situational syncope

Situational syncope causes fainting during certain situations, such as being overheated or dehydrated, feeling anxious or fearful, or being hungry.

Cardiac syncope

Cardiac syncope can be a symptom of serious cardiovascular conditions, including arrhythmia, blood vessel blockages, heart valve disease, and heart failure. Florida Heart, Vein and Vascular Institute provides diagnostic testing onsite to identify the underlying cause of syncope. The cardiology team creates a treatment plan to address the cause and reduce the frequency of syncope episodes.

When should I seek medical attention for fainting?

Schedule a diagnostic evaluation at Florida Heart, Vein and Vascular Institute if you faint often or have symptoms of syncope, such as:

• Lightheadedness
• Dizziness
• Blacking out
• Frequent drowsiness
• Vision changes
• Headaches

Because syncope can indicate you have heart failure or another serious condition, you should get a prompt diagnosis. The cardiology team offers electrocardiograms (EKG), exercise stress tests, and tilt table testing to evaluate your cardiovascular function. They can also use an implantable loop recorder to monitor your heart’s electrical activity. A specialist implants the device just under the skin of your chest to record information for up to three years.

How is syncope treated?

Florida Heart, Vein and Vascular Institute offers personalized care plans for syncope and cardiac-related causes. The cardiology team may initially recommend lifestyle and diet changes to prevent fainting episodes. You should also be mindful of the times you feel lightheaded or experience heart palpitations so you can sit or lie down to avoid passing out. You may also need prescription medications to regulate your heart’s rhythm if syncope results from arrhythmia or heart failure. The team also provides pacemakers for people with severe arrhythmias that contribute to frequent fainting.
