CCDS IBHRE Exam Questions and
Answers with Complete Rationales |
Verified | A+ Guide
• What kind of device is recommended for a SSS pt with no suspected
abnormality of AV conduction and not at increased future risk for AV
block? -✓✓Single-chamber atrial pacemaker
• What type of pacemaker is indicated for a SSS pt and maintenance of
AV synchrony during pacing is desired -✓✓SC Atrial Pacemaker
• How do you calculate energy? -✓✓E = (V^2)*t/R
• What is ohm's law? -✓✓V=IR (voltage = current x resistance)
• What are the 3 general pacemaker indications? -✓✓Sinus node
dysfunction
AV block
Vasovagal syncope
• What are the indications for a Dual-chamber pacemaker? -✓✓Sinus
node dysfunction:
AV synchrony during pacing desired
Suspected AV conduction abnormalities or increased risk for future AV
block
AV Block:
AV synchrony during pacing desired
Atrial pacing desired
Vasovagal syncope:
Sinus mechanism present
, • What are the indications for a VDD pacemaker? -✓✓AV Block:
To limit the number of pacer leads, able to sense atria and pace ventricle
to provide AV synchrony
Not appropriate for pts w/ atrial pacing indication
• What can chagas disease do to heart function? -✓✓Can cause AV
block and cardiomyopathy
• Class I LOE B-NR recommendation for TAVR pts -✓✓In patients who
have new AV block after TAVR associated with symptoms or
hemodynamic instability that does not resolve, permanent pacing is
recommended before discharge
• Class IIa and LOE B-NR recommendation for TAVR pts -✓✓In
patients with new persistent bundle branch block after TAVR, careful
surveillance for bradycardia is reasonable
• Class IIb and LOE B-NR recommendation for TAVR pts -✓✓In
patients with new persistent LBBB after TAVR, implantation of a PPM
may be considered
• What are the indications for a SC Ventricular Pacemaker? -✓✓SSS pt:
Maintenance of AV synchrony during pacing not necessary
Rate response available if desired
AV block pt:
Chronic afib so maintenance of AV synchrony during pacing isn't
required
RR available
Vasovagal pt:
Chronic Afib or other atrial tachy arrhythmias
