2. Ventricular Fibrillation/Pulseless Ventricular Tachycardia
• Check responsiveness
• Activate emergency response system
• Call for monitor/defibrillator
• CPR until defibrillator arrives
VF/PULSELESS VT
RAPID DEFIBRILLATION 200,300,360 J
PULSE Yes
ABC'S
Diagnostics
No
Epinephrine 1 mg IV push every 3-5 minutes
or
{Vasopressin 40 units IV push (not repeated)}
Defibrillate 360 J within 30-60 seconds
CONSIDER:
Amiodarone 300 mg bolus, followed by repeat 150 mg bolus after 10 minutes.
Lidocaine 1.5 mg/kg (maximum 3 mg/kg)
Procainamide 17mg/kg as 100 mg boluses every 3 min.
Magnesium Sulfate 2 g bolus (if indicated)
Buffers (if indicated)
• Continue attempts to defibrillate every 1-2 minutes
• Defibrillation does not have to be tied to drug administration
PRIMARY ABCD SURVEY
Airway: airway device placement
Breathing: confirm tube placement, oxygenate, ventilate
Circulation: continue CPR, IV access, administer drugs, confirm rhythm
Differential Diagnosis: search and treat reversible causes
SECONDARY ABCD SURVEY

VF/Pulseless VT
Notes:
NOTES:
• If rhythm changes after defibrillation, go to appropriate algorithm
• Treatable causes:
- infarction. ischemia
- drug overdose (TCA, cocaine, antiarrythmics)
- electrolyte disturbances (potassium, calcium, magnesium)
• Groups of three shocks at 360 J are acceptable for each defibrillation after the initial
escalating stacked shocks
• Biphasic defibrillation 150 J is as efficacious as monophasic defibrillation 360 J
• Buffers are indicated when hyperkalemia is suspected (renal failure) or TCA overdose

ASYSTOLE
ASYSTOLE
• confirm in three leads
• assess DNR status
Consider TCP in witnessed short " down time" arrests
Epinephrine 1 mg every 3-5 minutes
Atropine 3 mg bolus (maximum 0.04 mg/kg)
CONSIDER EARLY TERMINATION
NOTES:
• Look for reasons not to start resuscitation
• Vasopressin not recommended
• If the patient remains asystolic 5 minutes after all ACLS interventions are complete,
the arrest should be discontinued unless extenuating circumstances are present.
• Check responsiveness
• Activate emergency response system
• Call for monitor/defibrillator
• CPR until defibrillator arrives
PRIMARY ABCD SURVEY
Airway: airway device placement
Breathing: confirm tube placement, oxygenate, ventilate
Circulation: continue CPR, IV access, administer drugs, confirm rhythm
Differential Diagnosis: search and treat reversible causes
SECONDARY ABCD SURVEY

5. PULSELESS ELECTRICAL ACTIVITY (PEA)
(PEA is anything on the monitor EXCEPT Ventricular Fibrillation, Ventricular Tachycardia, Asystole)
PEA
EPINEPHRINE 1 mg every 3-5 minutes
ATROPINE 1 mg every 3-5 minutes, if heart rate < 60
NOTES:
• Narrow complex PEA has a better prognosis than wide complex, be diligent in searching for causes.
Consider cardioversion in narrow complex PEA with rates greater than 160
• Vasopressin not recommended pressor
• Assess for low flow states: doppler blood pressure, heart sounds, echocardiogram
(if available), agonal respirations.
REVERSIBLE CAUSES and TREATMENT
HYPOVOLEMIA: saline bolus, +/- blood
HYPOXIA: intubation, 100% oxygen
HYDROGEN ION (ACIDOSIS): intubation hyperventilation, +/- Bicarb
HYPER/HYPOKALEMIA: use appropriate medical protocol
HYPOTHERMIA: active core re-warming
TABLETS (OVERDOSE): use appropriate medical protocol
TAMPONADE: pericardiocentsis
TENSION PNEUMO: needle thoracostomy or chest tube
THROMBOSIS CORONARY: consider thrombolytics, PTCA or IABP
THROMBOSIS PULMONARY: consider thrombolytics
• Check responsiveness
• Activate emergency response system
• Call for monitor/defibrillator
• CPR until defibrillator arrives

BRADYCARDIA
PRIMARY ABCD SURVEY
• Assess airway, breathing, circulation
• monitor
NOTES:
• Atropine may be used in all unstable bradycardias, including heart blocks, although
it may not be effective in type II second degree and third degree blocks.
• If cause is found, such as an inferior MI, treat the cause and the rate.
SECONDARY ABCD SURVEY
• Oxygen, vital signs, IV access
• 12 lead EKG
• Focused history and physical
Is patient stable or unstable?
signs/symptoms hemodynamic compromise =
hypotension, new onset or worsening CHF, ischemic
chest pain, new onset of decreased level of consciousness
STABLE UNSTABLE
Type II, second degree heart block?
Third degree heart block?
NO YES
• Prepare for transvenous pacemaker
• If symptoms develop, use
transcutaneous pacemaker until
transvenous pacer placed
Observe
• Atropine 0.5 to 1.0 mg
• Transcutaneous Pacing, if available
• Dopamine 5-20 ug/kg/min
• Epinephrine 2-10 ug/min
• Prepare for transvenous pacemaker

7. TACHYCARDIAS
• Are there serious symptoms or signs due to the rate?
(hypotension, new onset or worsening CHF, ischemic chest pain,
new onset of decreased level of consciousness)
NOTES:
• If Adenosine reveals presence of flutter waves, go to the Atrial Fibrillation/Flutter algorithm
• Electricity is rarely a bad choice in wide complex tachycardias
• If polymorphic ventricular tachycardia (torsade) is present, consider Magnesium, Isoproterenol, overdrive pacing,
and correction of electrolyte disturbances. Type 1A antiarrythmics (Procainamide, Quinidine, Disopyramide) are
dangerous in this condition.
• If old EKG shows bundle branch block with QRS morphology identical to current QRS morphology,
then likely the rhythm is atrial flutter or SVT. Adenosine may be useful as a diagnostic agent in this situation.
• When in doubt, treat wide complex of unknown origin as ventricular tachycardia.
• Rate related signs and symptoms rarely occur at rates < 150 beats per minute.In patients with known
preexisting impaired LV function (EF < 40%), cardioversion can be used with caution

ATRIAL FIBRILLATION/FLUTTER
• Stable/unstable (hypotension, new onset or worsening CHF,
ischemic chest pain, new onset of decreased level of consciousness)
• History of WPW?
• Duration of arrhythmia
• Ejection fraction known or unknown
• Current medications (beware of antiarrythmics and Sotalol)
NOTES:
• Electricity is rarely the wrong choice
• Err on the side of caution
• Consider anticoagulation for all patients prior to cardioversion (low molecular weight heparin +/- Coumadin)
• Use only one antiarrythmic when attempting chemical conversion
• Suspect WPW when rate is > 200 or wide complex
• Beware of Calcium Channel Blockers in WPW
