Definition
“Defibrillation is the delivery of an electric
current through the chest wall and heart for the
purpose of terminating ventricular fibrillation or
pulseless ventricular tachycardia and restoring a
perfusing rhythm.”
Teamwork* Integrity*3Professionalism* Service*
A & P of the Heart
A network of specialized tissue, capable of
conducting electrical current, runs throughout the
heart muscle.
As electrical impulses travel through this network,
coordinated contractions of the heart muscle
occur.
Teamwork* Integrity*4 Professionalism* Service*
Electrical Pathway
• Sinoatrial Node (SA)
• Atrioventricular Node
(AV)
• Bundle of His
• Bundle Branches
• Purkinje Fibers

Teamwork* Integrity* Professionalism* Service*
Heart Function
• Electrical
• Electrical impulses
through the heart.
• Evaluated with ECG
monitor.
• Mechanical
• Actual pumping of the
heart.
• Evaluated by checking
pulse.
• An electrical rhythm does
not mean there is a
pulse!
Teamwork* Integrity*6 Professionalism* Service*
Shockable Rhythms
• Pulseless Ventricular Tachycardia (VT) may be the initial rhythm for a patient in
cardiac arrest.
• Ventricular Fibrillation (VFib) is the most frequent rhythm present when a patient
is found in cardiac arrest.
• Ventricular Fibrillation is a useless quivering of the heart that results in no blood
flow, therefore no pulse.
• Early Defibrillation is the only effective treatment for Ventricular Fibrillation.
• AEDs shock Pulseless Ventricular Tachycardia (VT) and Ventricular Fibrillation
(VFib).

AEDs and Ventricular Fibrillation/
Pulseless Ventricular Tachycardia
• Defibrillation “shocks” the heart in an effort to restore normal
electrical activity of the heart.
• Defibrillation is the only effective treatment for VF/Pulseless
VT, once the patient’s pump has been “primed”
• The ability to successfully defibrillate a patient into a normal
rhythm diminishes rapidly over time.

Effective Adherence of Pads
• Sweaty chest
• Dry with a towel
• Do not use alcohol
• Hairy chest
• Shaving may be needed
• Ultimate goal is to have
complete skin contact.
Teamwork* Integrity* Professionalism* Service*
23
Current AED Programming
• Loudoun County AED’s are setup to prompt
witnessed or unwitnessed arrest instructions
• If the AED asks if you witnessed the arrest, push
‘CANCEL’
• This means that the AED has detected a
shockable rhythm
• If the AED doesn’t ask, then continue CPR as
directed by the AED
• This means that the AED has detected a nonshockable rhythm
24
After pushing cancel, clear patient in
preparation for a shock

chest.
 Use gloves when you remove
it.
Teamwork* Integrity* 34
Professionalism* Service*
Artificial Pacemakers
• Pulse generator and wires
to the heart.
• Usually found on the left
side of the chest.
• If found on the right, do not
place the pad over the
pacemaker.
• A direct shock to the
pacemaker could cause it to
reprogram.
Teamwork* Integrity* 35
Professionalism* Service*
Automated Internal Cardiac
Defibrillator (AICD)
• Used in patients with
recurrent arrhythmias
• If found on the right,
do not place the pad

Trauma & Obvious Death
• AED should not be attached to a patient that is
obviously dead.
• Signs incompatible with life, e.g. rigor mortis, etc.
• Signs of injuries incompatible with life, e.g.
decapitation
• AED may be attached to a trauma patient in
cardiac arrest since the cardiac arrest may have
caused the trauma.
