Syncope

Comprehensive evaluation of fainting episodes with same-day diagnostics when possible.

Syncope is a sudden, transient loss of consciousness caused by a brief reduction in blood flow to the brain, followed by spontaneous and complete recovery. It ranges from benign reflex fainting that needs little more than reassurance to dangerous cardiac arrhythmias and structural heart disease that require urgent diagnosis. Distinguishing the type — reflex (vasovagal), orthostatic, or cardiac — is the central question in every syncope workup, because the prognosis and treatment differ enormously. Dr. Kedan evaluates syncope as a diagnostic puzzle and a risk-stratification problem, using history, exam, EKG, echocardiography, and ambulatory monitoring to make sure dangerous causes are not missed.

What Cardiolucent Evaluates

  • Detailed history of the episode: triggers, prodrome, posture, witnesses
  • Orthostatic vital signs and full cardiac examination
  • 12-lead EKG with attention to conduction and ischemic features
  • Echocardiography with POCUS at the visit when structural disease is suspected
  • Extended ambulatory rhythm monitoring or implantable loop recorder when appropriate
  • Tilt table testing for suspected reflex syncope
  • Coordination with electrophysiology at Cedars-Sinai when arrhythmia is suspected

Common Symptoms

  • Brief loss of consciousness with spontaneous recovery
  • Lightheadedness, warmth, nausea, or tunnel vision before fainting (prodrome) in reflex syncope
  • Sudden loss of consciousness without warning, especially during exertion, suggests cardiac cause
  • Palpitations preceding the episode
  • Witnessed brief seizure-like movements, which can occur during syncope
  • Quick orientation after the episode (unlike postictal confusion after a seizure)

Risk Factors

  • Known structural heart disease, including cardiomyopathy or valvular disease
  • Heart rhythm disorders (bradycardia, tachycardia, conduction disease)
  • Family history of sudden death or inherited arrhythmia
  • Age over 60
  • Dehydration, blood loss, or medications that lower blood pressure
  • Diabetes and autonomic dysfunction
  • Prolonged standing or hot environments for reflex syncope

How Cardiolucent Approaches Treatment

Treatment is entirely cause-dependent. Reflex syncope is managed with hydration, salt, counter-pressure maneuvers, and triggering-situation education, with medication reserved for selected patients. Orthostatic syncope is addressed by medication review, salt and fluids, compression stockings, and sometimes targeted medications. Cardiac syncope from arrhythmia or structural disease requires definitive treatment such as pacemaker or defibrillator implantation, ablation, or valve intervention, coordinated with electrophysiology and structural heart specialists at Cedars-Sinai. Dr. Kedan ensures the diagnostic process is thorough enough to identify the dangerous causes before treating the benign ones.

Common Questions

Frequently Asked Questions

What is syncope?
Syncope is a temporary loss of consciousness caused by a brief drop in blood flow to the brain, with spontaneous and complete recovery. It is a symptom rather than a disease, and the cause can range from harmless to dangerous.
Why does fainting need a cardiology workup?
While most fainting is benign, a meaningful subset reflects an arrhythmia or structural heart disease that can be life-threatening. Cardiology evaluation is designed to separate these patients from the much larger group with reflex or orthostatic syncope so dangerous causes are not missed.
How do you tell the difference between a faint and a seizure?
Syncope is usually brief, with quick orientation afterward; a seizure typically involves a longer period of confusion, tongue biting, or loss of bladder control. Brief jerking movements can occur with syncope, however, and the history from witnesses is crucial.
What testing will I need?
Every patient gets a careful history, exam, orthostatic vitals, and EKG. Echocardiography is added when structural disease is suspected. Extended ambulatory monitoring or an implantable loop recorder is used when episodes are infrequent. Tilt table testing is reserved for suspected reflex syncope when the diagnosis is unclear.
What features suggest a dangerous cause?
Syncope during exertion, syncope without warning, syncope while lying flat, syncope with palpitations, a family history of sudden death, or a known cardiac condition all suggest cardiac syncope and warrant aggressive evaluation. Dr. Kedan looks for these red flags at the first visit.
How is reflex (vasovagal) syncope treated?
Most patients improve with adequate hydration, salt intake, recognition of triggers, and counter-pressure maneuvers (such as leg crossing or hand gripping when symptoms begin). Medications and, rarely, pacemakers are reserved for select refractory cases.
When is a pacemaker or defibrillator needed?
A pacemaker is appropriate for syncope from documented severe bradycardia or conduction disease. An implantable defibrillator is appropriate for syncope from life-threatening ventricular arrhythmias or in specific structural heart conditions where sudden death risk is high. These decisions are made jointly with electrophysiology.
Can I drive after a syncopal episode?
Driving restrictions after syncope depend on the suspected cause and state regulations. Cardiac syncope generally requires a defined period of being symptom-free, and Dr. Kedan reviews the specific recommendations for your situation.
What does Cardiolucent do differently for syncope evaluation?
Same-day POCUS, EKG review at the visit, extended appointment lengths, and direct coordination with electrophysiology let Dr. Kedan move efficiently from history to diagnosis. Patients are not left for weeks waiting on disconnected test results.
How do I schedule a consultation?
Call (310) 304-5555 or use the contact form to schedule with Dr. Kedan at the Beverly Hills office. Cardiolucent does not bill Medicare or insurance; a detailed superbill is provided for any out-of-network reimbursement.
