Question

which of the following list the electrical activity of theheart in correct sequence? A) rapid depolarization, plateau, repolarization, refractoryperiod B) rapid depolarization, repolarization, plateau,refractory period C) refractory period, repolarization, rapid depolarization,plateau D) repolarization, rapid depolarization, refractory period,plateau E) plateau, rapid depolarization, repolariization, refractoryperiod which of the following list the electrical activity of theheart in correct sequence? A) rapid depolarization, plateau, repolarization, refractoryperiod B) rapid depolarization, repolarization, plateau,refractory period C) refractory period, repolarization, rapid depolarization,plateau D) repolarization, rapid depolarization, refractory period,plateau E) plateau, rapid depolarization, repolariization, refractoryperiod B) rapid depolarization, repolarization, plateau,refractory period C) refractory period, repolarization, rapid depolarization,plateau D) repolarization, rapid depolarization, refractory period,plateau E) plateau, rapid depolarization, repolariization, refractoryperiod

Explanation / Answer

The answer is B After rapid depolarization, in the phase I ,the repolarizationstarts rapidly but partially It is followed by the plateau phase which is followed bythe phase III where repolarization is complete and then therefractory period. As depolarization is the first step C,D,E are ruled out
