22
Q

What are the indications for a Pacemaker?

A

SA/AV node Disease

Long QT Syndrome

Hypertrophic/Dilated Cardiomyopathy

23
Q

What is the Position 1 on the Pacemaker and what are the possible settings?

A

Chamber Paced

O, A, V, D

24
Q

What is the Position 2 on the Pacemaker and what are the possible settings?

A

Chamber Sensed

O, A, V, D

25
Q

What is the Position 3 on the Pacemaker and what are the possible settings?

A

Response to Sensing

O: None

I: Inhibited

T: Triggered

D: Dual (T+I)

26
Q

What is the Position 4 on the Pacemaker and what are the possible settings?

A

Programmability

O: None

R: Rate Modulation - Increases the pacer’s lower HR limit when Increased Myocardial O2 Demand may be needed

27
Q

What is the Position 5 on the Pacemaker and what are the possible settings?

A

Multisite Pacing - Pacing of BOTH Atria and/or BOTH Ventricles

O, A, V, D

28
Q

What is Failure to Capture?

A

When Pacer’s Electrical Output fails to cause Myocardial Depolarization

29
Q

What is Failure to Sense?

A

When Pacer fails to recognize Intrinsic Cardiac Electrical Activity

30
Q

What are the indications for an AICD?

A

V-Tach/Fib

EF < 30% Post MI

Cardiomyopathy w/ EF < 35%

Awaiting Heart Transplant

Long QT Syndrome

Hypertrophic Cardiomyopathy

31
Q

A

Shock Chambers

O, A, V, D

32
Q

What is the Position II on an AICD and what are the possible settings?

A

Anti-Tachycardia Pacing Chambers

O, A, V, D

33
Q

What is the Position III on an AICD and what are the possible settings?

A

Tachycardia Detection

E: Electrocardiogram

H: Hemodynamic

34
Q

What is the Position IV on an AICD and what are the possible settings?

A

Anti-Bradycardia Pacing Chambers

O, A, V, D

35
Q

At what energy level does an AICD cardiovert a V-Tach Rhythm?

A

1-30 Joules

36
Q

At what energy level does an AICD defibrillate a V-Fib Rhythm?

A

10-30 Joules x 6 Shocks if needed

37
Q

What is the most common source for Electromagnetic Interference w/ Pacemakers/AICDs?

A

Electrocautery

38
Q

Which type of Cautery poses less risk of Electromagnetic Interference?

A

Bipolar Cautery w/ the Anode & Cathode at the tip vs. A Monopolar Cautery w/ a Grounding Pad

39
Q

What happens when a Magnet is placed on a Pacemaker?

A

Sets Pacemaker to Asynchronous Pacing Rate & Disables Rate Modulation

40
Q

What happens when you place a Magnet on an AICD?

A

AICD wont be able to Shock VT or VF

41
Q

What happens when a Magnet is placed on a Dual Pacemaker or ICD?

A

ONLY disables Shock Function
