Adams-Stokes Syndrome

General information
Heart to the notice of the atrioventricular node (AV Note) Although the normal late, specialized in ventricular conduction system / His bundle or cardiac conduction system is blocked in all three fascicles, which can be defined as AV block İnfranodal AV block is common in patients with advanced age. It can result in unconsciousness and convulsions. If this is connected to the blog called syncope infranodal Adams Stokes crisis. Adams Stokes Crisis, unannounced and soon revealed. However, the crisis tends to increasingly frequent. Pulse rate usually between 20 to 50 minutes. Jugular venous pulse "Giant Waves" noticeable.
What are the affected systems?
Cardiovascular System, Nervous System
What are the symptoms?
Acute bradycardia (20-50 / min)
Hypotension
Paleness
Position does not depend on feelings or effort or loss of consciousness
Syncope or sudden occurrence of similar symptoms (get palpitations or not)
Jugular venous pulse in the giant waves.
What are the reasons?
Medicines
* Calcium channel blockers
* Beta blockers
* Digoxin
* Ouabain
* Propafenone
* Clonidine

AV node holding myocardial ischemia
And holding the heart conduction system disease or fibrous infiltration (amyloid, syphilis, tumors)
Age-related degeneration of the AV node
Neuromuscular diseases (myotonic muscular dystrophy or Kearns-Sayre Syndrome)
What are the risk factors?
Calcium channel blockers, beta blockers, digoxin, ouabain, propafenone, the use of the drug clonidine etc.
Coronary artery disease
AV node dysfunction
Acute myocardial infarction (especially acute occlusion of the right coronary artery)
amyloidosis
Chagas' disease
Heart involving connective tissue disease (systemic lupus eritemotosus, rheumatoid arthritis)
What are the pathological findings?
Serum digoxin levels have increased. Serum cardiac enzymes increased. ECG event monitoring or Holter monitor that, and slowed ventricular shows the kaçaksız transient complete heart block.
What are the tests that can be done?
electrocardiography
For Monitoring
Holter Monitoring
What are the diagnostic procedures?
coronary catheterization to exclude coronary ischemia
electrophysiological tests to evaluate the AV nodal conduction state
myocardial biopsy is suspected infiltrative disease
What are the maintenance and precautions?
hospitalization where monitoring is required.
Continuous treatment, ambulatory monitoring.
cardiac monitoring during Operations
Operations available during trans-thoracic pace
atropine during Operations
Placing temporary pace-maker's operations during the likelihood
Complete heart block when the temporary pacemaker is irreversible implementation
The diagnosis were diagnosed and about the pace should be placed in the patient enough information about it.
What are the ways of treatment?
Atropine 1 mg IV-style scarves are given in hypotension, along with complete heart block. Total dose of epinephrine may be repeated until it becomes 2 mg, 1 mg of 1: 10.000 IV scarves to be given in case of complete heart block associated with asystole, it may be repeated every 5 minutes. Isoproterenol drop in 1 mg and 250 mL of 5% dextrose or 5 micrograms per minute with normal saline perfusion as in patients despite the ongoing hypotension and bradycardia atropine treatment for one full infranodal AV block; the right ventricular endocardial, demand-pace maker that will give notice as soon as the need is located.
