Addition of normal values of the quantities PR, QRS, and QT

Could not somebody add the normal values of the quantities PR, QRS, and QT or else I would.

down stroke on the EKG

What is the interpretations of the down stroke in the EKG like the second half of the P wave? And what action of the electrical activity of the heart does it represents? And the same I'm wondering with the T wave? Willing student (talk) 07:16, 22 December 2021 (UTC)[reply]

Description of using of RL electrode for voltage calculation is must be.

Description of using of RL electrode for voltage calculation is must be at this article. Or the non-using of it must be indicated explicitly. Voproshatel (talk) 16:07, 7 October 2023 (UTC)[reply]

Left or right leg?

In the table under section "Electrodes applied to patient's body", electrode III is place "On the right leg, lower end of inner aspect of calf muscle. (Avoid bony prominences)" The figures show the left leg. That was the case in my recent ECG. I am just a patient and not a medical professional, but is right correct? — Preceding unsigned comment added by KudzuVine (talk • contribs)

The sources linked in the article describe several different placements of electrodes. The placement is related to how the equipment works and the signals are analyzed. Unfortunately the Table is not correct when compared to the references. Johnjbarton (talk) 18:45, 5 February 2025 (UTC)[reply]
