Question 237 · LEK · Defibrillation

Which of the following is a true statement regarding tachycardia?

  1. A. in the case of atrial flutter and paroxysmal supraventricular tachycardia, the first delivered shock should be 70-120 J.
  2. B. in the case of atrial fibrillation, it is more advisable to use stepwise increases in energy rather than a maximal-energy synchronized shock available for a given device.
  3. C. to achieve conversion of atrial and ventricular tachyarrhythmia, the shock must by synchronized with the Q wave on the ECG.
  4. D. in the case of ventricular tachycardia with a pulse, the first shock should be 70-100 J.
  5. E. none of the above.
Hint

Recall ERC energy levels for synchronised cardioversion of different rhythms and what part of the ECG the shock is synchronised to.
