Question

m 1 - chapters 14 and 15 (2 attempts) which ecg wave is correctly described? multiple choice qrs complex: depolarization of atria p wave: depolarization of atria qrs complex: repolarization of ventricles t wave: depolarization of ventricles

Explanation:

In an electrocardiogram (ECG), the P - wave represents the depolarization of the atria. The QRS complex represents the depolarization of the ventricles, not the atria or repolarization of the ventricles. The T - wave represents the repolarization of the ventricles, not depolarization.

Answer:

B. P wave: depolarization of atria
