    • What is A-Fib tion tanding of Atrial Fibrilla A simple UndersBy Devon Lewis RN, BSN
    • Wh at is A-Fib?● A-fib is a heart condition that affects many people. ● It is an irregular heart rhythm that can have serious consequences if not addressed or regulated.
    • electrical conduction The hearts● In a normal heart rhythm the Sinoatrial (SA)node produces an electrical current. ● This current stimulates the heart and causes it to contract and beat.
    • electrical conduction The hearts  ● The SA node controls the heart to beat 60-100 beats/min.
    • The hearts conduction
    • S ome Cause s of A-Fib● Heart Attack● High Blood Pressure● Hyperactive Thyroid● Heart Defects● Sick Sinus Syndrome● Viral infection● Surgery● Stimulants● Sleep Apnea● Heart DefectsSource Mayo Clinic
    • The onset of A-Fib● The hearts electrical system goes haywire from a condition priorly mentioned. ● The electrical signal comes from a place above the SA node.
    • The onset of A-Fib● The atrium starts to quiver from this electrical disturbance. ● The heart rate becomes irregular. 
    • The onset of A-Fib● The heart rate can become 120 even up above 170 beats/min. ● The SA node is no longer in control of regulating the heart rate.
    • The onset of A-Fib● With a rapid heart rate one can become short of breath and light headed and hypotension (low blood pressure).
    • A-Fib untreated● Can cause blood clots to form because blood in the atrium becomes stagnant. ● Blood from the left ventricle can shoot a clot into the brain causing a stroke (see next slide).
    • A -Fib untrea ted cont.● A-fib untreated can also cause heart failure.
    • A-Fib treatments● Cardioversion (shocking the heart)● Medications to control rate and rhythm cardizem, amiodarone, etc.● Sometimes the heart converts to regular rhythm on its own.
    • -Fib treatm ents cont. A● The use of anticoagulants to prevent blood clots, such as Coumadin or Pradaxa 
    • -Fib treatm ents cont. A● If a heart rate can not be controlled by medications an ablation (burning of) SA node and placement of a pacemaker may be necessary. 
    • The End.● This is just for general educational information.
