What is this Rhythm?
3rd Degree AV Block
What is this Rhythm?

What are the indications for a Pacemaker?
SA/AV node Disease
Long QT Syndrome
Hypertrophic/Dilated Cardiomyopathy
What is the Position 1 on the Pacemaker and what are the possible settings?
Chamber Paced
O, A, V, D
What is the Position 2 on the Pacemaker and what are the possible settings?
Chamber Sensed
O, A, V, D
What is the Position 3 on the Pacemaker and what are the possible settings?
Response to Sensing
O: None
I: Inhibited
T: Triggered
D: Dual (T+I)
What is the Position 4 on the Pacemaker and what are the possible settings?
Programmability
O: None
R: Rate Modulation - Increases the pacer’s lower HR limit when Increased Myocardial O2 Demand may be needed
What is the Position 5 on the Pacemaker and what are the possible settings?
Multisite Pacing - Pacing of BOTH Atria and/or BOTH Ventricles
O, A, V, D
What is Failure to Capture?
When Pacer’s Electrical Output fails to cause Myocardial Depolarization
What is Failure to Sense?
When Pacer fails to recognize Intrinsic Cardiac Electrical Activity
What are the indications for an AICD?
V-Tach/Fib
EF < 30% Post MI
Cardiomyopathy w/ EF < 35%
Awaiting Heart Transplant
Long QT Syndrome
Hypertrophic Cardiomyopathy
What is the Position I on an AICD and what are the possible settings?
Shock Chambers
O, A, V, D
What is the Position II on an AICD and what are the possible settings?
Anti-Tachycardia Pacing Chambers
O, A, V, D
What is the Position III on an AICD and what are the possible settings?
Tachycardia Detection
E: Electrocardiogram
H: Hemodynamic
What is the Position IV on an AICD and what are the possible settings?
Anti-Bradycardia Pacing Chambers
O, A, V, D
At what energy level does an AICD cardiovert a V-Tach Rhythm?
1-30 Joules
At what energy level does an AICD defibrillate a V-Fib Rhythm?
10-30 Joules x 6 Shocks if needed
What is the most common source for Electromagnetic Interference w/ Pacemakers/AICDs?
Electrocautery
Which type of Cautery poses less risk of Electromagnetic Interference?
Bipolar Cautery w/ the Anode & Cathode at the tip vs. A Monopolar Cautery w/ a Grounding Pad
What happens when a Magnet is placed on a Pacemaker?
Sets Pacemaker to Asynchronous Pacing Rate & Disables Rate Modulation
What happens when you place a Magnet on an AICD?
AICD wont be able to Shock VT or VF
What happens when a Magnet is placed on a Dual Pacemaker or ICD?
ONLY disables Shock Function
