Question
The conduction mechanism consists of three stages. Which of the following is the correct order of events during this process?
Answer: Option A
:
A
The conduction mechanism can be broken down into three major stages. The stages in order are atrial depolarization, ventricular depolarization which is followed by combined atrial and ventricular repolarization. Depolarization refers to the decrease in negative charge in the conduction cells of the heart and this drives contraction of the heart chambers.Repolarisation on the other hand increases negative charge in the conduction cells of the heart bringing about relaxation of heart chambers.
