Multiple Choice

Which statement best describes why clinicians use a defibrillator?

• A) The ventricles of the heart are so large that only a strong current can make them depolarize, which is needed in order for them to contract and get blood to the body.
• B) The applied current opens up voltage gated calcium channels in the atria causing the heart to begin a new P wave.
• C) The applied current depolarizes all the muscle cells at the same time, returning synchronous electrical activity to the heart.
• D) A defibrillator takes the place of the SA node and must be applied every minute to keep the heart rate normal until it regains its strength and beats on its own.
• E) The applied current repolarizes the cells of the heart, hence resetting the heart for normal rhythm.
