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.
