An electrocardiogram (ECG) is shown below. whe 1) Please identify the structure(s) of heart and the electrical event(s) that result in the P-R segment (shown in green). 2) Considering that the electrical system regulates the heart contraction (mechanical events), please explain how the electrical event(s) you identified in question 1) regulates the heart contraction, and the importance of this regulation. (Please correlate the electrical event(s) with mechanical events of the heart)
