Question
Match up the following phases of the ECG with their correlated electrical events.P waveQRS ComplexT wave
Solution
P wave: This corresponds to the depolarization of the atria, which means it represents the electrical impulse traveling through the atria, causing them to contract.
QRS Complex: This corresponds to the depolarization of the ventricles, which leads to ventricular contraction. It represents the electrical activity causing the ventricles to contract.
T wave: This corresponds to the repolarization of the ventricles, or the period where the ventricles are resetting electrically and preparing for the next contraction.
