What occurs after a successful defibrillation shock?
- A. Return to normal rhythm
- B. Persistent rhythm disruption
- C. Continued arrhythmia
- D. Increase in dysrhythmia
Answer:
A. Return to normal rhythm
Defibrillation uses electric shock to start a stopped heart — or momentarily stop a chaotic rhythm — and get the heart beating normally again.

How is constant current maintained in the ZOLL® defibrillator's waveform?
- A. By increasing voltage
- B. By using resistors
- C. By varying joules
- D. By reducing pulse width
Answer:
B. By using resistors
To compensate for varying levels of impedance in patients, ZOLL defibrillators use resistors to maintain a constant current.

What is the main determinant for defibrillation success?
- A. High energy
- B. Low voltage
- C. High current
- D. Short duration
Answer:
C. High current
While defibrillation shocks are delivered in joules, it is well documented that it’s current that defibrillates the heart.

What type of waveform do ZOLL® defibrillators use?
- A. Triangular Biphasic
- B. Monophasic
- C. Rectilinear Biphasic
- D. Square Wave
Answer:
C. Rectilinear Biphasic
ZOLL® defibrillators use the Rectilinear Biphasic™ waveform. While defibrillation shocks are delivered in joules, it’s well documented that it is current that defibrillates the heart.
