Neuro- Cardiogenic Syncope
Neuro- Cardiogenic Syncope
Syncope - Definition
• Syncope; is a transient loss of conciousness and
postural tone with spontaneous recovery
• Loss of consiousness is a result of ,
sudden and shorterm serebral hipoperfusion
• Restoration of conciousness or orientation after a
syncopal episode is usually immediate, and
does nor require electrical or chemical therapy
for reversal
Neurocardiogenic Syncope
Prevelans
• 1- 6 % of all hospital admissions
• 3 % of Emergency Department visits
Prognosis – 1 year mortality risc
• Cardiogenic Syncope
: 24 %
• Non-Cardiogenic Syncope : 4 %
Neurocardiogenic Syncope
Etiology – Cardiac Causes
Anatomic causes
Aortic stenosis
HOCM
Myocardial ischemia / infarction
Aortic dissection
Cardiac tamponade
Atrial myxoma
Severe pulmonary hypertension
Severe pulmonary emboli
Subclavian steal syndrome
Fallot tetralogy
Arrhythmic causes
Tachy-arrhythmias
- Supraventricular tachycardia
- Ventricular tachycardia
- Long-QT syndrome (primary /secondary)
- Brugada syndrome
Brady-arrythmia
- Atrioventricular block
- Pace-maker dysfunction
- ICD dysfunction
- Sinus node dysfunction / bradycardia
Sick Sinus Syndrome
Neurocardiogenic Syncope
“Primary Evaluation”
• Detailed clinical history obtained from the patient or
the witness of the syncopal episode, about the period
just before or after the episode will give clues about
the etiology
• Ortostatic blood pressure measurements and careful
physical examination including oscultation of
cardiac murmurs and carotis bruits
• Standart ECG
Neurocardiogenic Syncope
Classification of syncope
• Neurocardiogenic syndromes
e.g. vasovagal, carotid sinus hypersensitivity, situational
• Ortostatic
• Primary cause : cardiac arrhythmia – conduction
disturbances
e.g. Bradycardia, Tachycardia, AV-Block, etc
• Structural cardiac or cardiopulmonary diseases
e.g. acute myocardial infarction, aortic dissection,
acute pulmonary emboli, etc
Neuro- Cardiogenic Syncope
Non-syncope seizures
• Syncope-like conditions, with loss or impairment of
consciousness
e.g. epileptic seizures, TIA, etc
• Syncope-like conditions, where the patient is conscious
e.g. Psycogenic syncope (histerical, somatization disorders), etc
Neuro- Cardiogenic Syncope
Clinical features associated with non-syncope seizure
• Post-seizure >5 min confusion
(epileptic seizure)
• Long lasting tonic-clonic movements with the onset of
the seizure
(epileptic seizure)
• Frequent somatic complaints without accompanying
organic heart disease
(psycogenic)
• Vertigo, dizartria, diplopia (Transient Ischemic Attack)
Neuro- Cardiogenic Syncope
Diagnostic Criteria – Certain (I)
Vasovagal syncope; Syncope with typical prodromal symptoms
which is provoked with fear, severe pain, emotional stress, catheter
instrumentation, or after prolonged standing in hot enviorement
Situational syncope; Syncope produced with vagal stimuli, like
diüresis, frequeny coughing, defecation or swollowing
Ortostatic syncope; Syncope or presyncope associated withg
documented ortostatic hipotension
(Sudden fall of SBP > 20 mmHg or < 90 mmHg)
Neuro- Cardiogenic Syncope
Diagnostic Criteria – Certain (II)
Syncope secondary to cardiac ischemia;
ECG documentation of acute ischemia or infarction
Syncope secondary to cardiac arrhythmia ;
ECG documentation of
•
•
•
•
•
Sinüs bradycardia (< 40 beat/min or repetitive sinoatrial
block or sinus pause > 3 second)
Atrioventriküler block (2nd degree Mobitz Type II or
3rd degree)
Alternating LBBB or RBBB
Rapid paroxismal supraventricular tachycardia or ventricular
tachtcardia
Pace-maker dysfunction associated with cardiac pause
Neuro- Cardiogenic Syncope
Diagnostic Criteria - Probable
Conditions related with CARDIAC syncope ;
• Supine
• Post egzersize
• Post palpitation
• Known serious organic heart disease
• ECG disturbances
- wide QRS complex (>0.12 sec)
- AV conduction disturbances
- Post-meal at 1 hour
- Post egzersize
- Following with new drug administration or
after change of the dose

Neuro - Cardiogenic Syncope
Neuro- Cardiogenic Syncope
Which patients should be hospitalised
• Syncope secondary to a cardiac pathology
• Syncope resulted with serious injury
• Frequent syncope attacks
Neuro- Cardiogenic Syncope
Diagnostic Tests
• Carotid Sinus Massage
• Tilt Table Test
• Holter monitorörization
• Echocardiyography
• Egzersize Test
• External or Internal Loop Recorders
• Electrophysiologic Study (EPS)
• Cardiac Catheterisation and coronary anjiography
• Neurologic and pschchiatric evaluation
