What is Syncope?

Syncope is a brief loss of consciousness with spontaneous recovery. It occurs when blood flow to the brain temporarily decreases, leading to fainting.

Although many cases are not life-threatening, syncope should always be medically evaluated to rule out cardiac causes, particularly in adults or individuals with heart disease risk factors.

What causes Syncope or Fainting?

The causes of syncope fall into three main categories.

1. Reflex (Neurally Mediated) Syncope

This is the most common type and includes vasovagal fainting. It occurs when the autonomic nervous system temporarily malfunctions, causing a sudden drop in heart rate or blood pressure.

Common triggers include:

• Emotional stress

• Pain

• Prolonged standing

• Dehydration

• Heat exposure

2. Orthostatic Syncope

Orthostatic syncope occurs when blood pressure drops significantly upon standing. Causes may include:

• Dehydration

• Electrolyte imbalance

• Medication side effects

• Dysautonomia

• Postural orthostatic tachycardia syndrome (POTS)

This form of syncope is related to impaired blood vessel tone and circulatory regulation.

3. Cardiogenic Syncope (Cardiac Fainting)

This is the most serious category and requires urgent evaluation.

It may result from:

• Arrhythmias (abnormal heart rhythms)

• Bradycardia or tachycardia

• Structural heart disease

• Severe valve disorders

• Cardiomyopathy

Cardiac syncope can occur suddenly without warning and may increase the risk of serious complications. Identifying whether fainting is heart-related is a critical part of evaluation.

Is my fainting dangerous?

You may be at higher risk if you:

• Faint during physical activity

• Have known heart disease

• Have a family history of sudden cardiac death

• Experience chest pain or palpitations before fainting

• Have an abnormal ECG

• Are over age 60 with new-onset syncope

If any of these apply to you, prompt cardiology evaluation is strongly recommended.

When should I seek medical attention for Fainting?

Schedule a prompt cardiology evaluation if you experience:

• Recurrent fainting episodes

• Fainting during exertion

• Fainting without warning

• Heart palpitations before passing out

• Chest pain

• Shortness of breath

• Dizziness or lightheadedness

• Blurry vision

• Cold, clammy skin

Seek emergency care if fainting is accompanied by chest pain, severe shortness of breath, or occurs during physical activity.

How is Syncope evaluated?

At Vivify Medical, syncope evaluation begins with a detailed medical history and physical examination.

Diagnostic testing available in-office may include:

• Electrocardiogram (ECG)

• Echocardiogram

• Exercise stress testing

• Mobile cardiac telemetry monitoring

• Ambulatory rhythm monitoring

These tests help identify:

• Abnormal heart rhythms

• Structural heart abnormalities

• Valve disease

• Exercise-induced arrhythmias

If further specialized evaluation is required, we coordinate care with leading specialists and hospitals in New York City to ensure comprehensive assessment.

Our goal is to determine whether your fainting is reflex-mediated, orthostatic, or cardiac in origin.

Syncope vs Seizure: How we differentiate

Many patients worry that fainting may represent a seizure. We evaluate:

• Presence of convulsive movements

• Tongue biting

• Loss of bladder control

• Post-event confusion

• Recovery time

• Cardiac rhythm findings

A careful history and cardiac evaluation help distinguish between neurological and cardiac causes.

How is Syncope/Fainting treated?

Treatment depends on the underlying cause.

For reflex or orthostatic syncope, management may include:

• Increased hydration

• Dietary modifications

• Electrolyte optimization

• Compression stockings

• Specialized exercise programs

• Positional awareness and defensive maneuvers

If syncope is related to an autonomic nervous system imbalance, treatment focuses on stabilizing blood pressure and heart rate regulation.

For cardiogenic syncope, treatment may include:

• Medication to regulate heart rhythm

• Adjustment of existing medications

• Pacemaker implantation (when indicated)

• Referral for advanced electrophysiology evaluation

Vivify Medical develops individualized treatment plans based on cardiovascular risk and diagnostic findings.
