Analysing 'resting' & 'after excercise' ECG'S

  1. Nov 11, 2015 #1
    i Need to analyse the changes to parts of the ECG after exercise in comparison to the heart ecg before exercise. (see attached images).

    the questions are:

    1. After exercise, the T-Q interval?
    I put is no longer visible, but it was wrong.

    2. Changes in the R wave after exercise is due to?


    Any ideas?

    You need to show more effort on your schoolwork. We do not do your schoolwork for you here. What reading have you been doing about this?

    Ok, I've been doing reading about it, but finding it difficult.

    For Q1. Im thinking that the T-Q interval has gotten smaller in width, so the pace is going much faster, than when at resting

    for q.2. The height of the R wave has increased after exercise, but i dont know what this is due to

    Sounds right.
    I'm not seeing any difference in height. What happens during exercise? How do the body and the heart adjust to accommodate the higher demand for O2 and CO2 management?

    And what does the R wave represent? What generates it?

    the heart has to pump faster to accommodate; so send the signals throughout to the nodes quicker

    the R wave is the depolarization of the electrical signal through from the purkinjee fibres to the ventricles

    I did a Google search on ECG Changes During Exercise, and got some great hits. One of the first ones was for humankinetics.com, and it should help you a lot. Try the same Google search to find the link. :smile:
