exercise physiology ecg trace

Introduction:
For this assignment I have been asked to describe an ECG trace and identify which areas change during exercise, describe increase in blood pressure, shows what happens to blood flow and draw and label a oxygen disassociation curve.


ECGs are used to measure change in electrical patterns of the heart. ECG is short for electrocardiogram. This measures how electrical impulses that make the heart move. This also measures electrical activity and electrical signals in the heart.


Above is a picture of an ECG trace. The first little lump is called the P wave. The large wave after that is called the QRS and the last wave is called the T wave.
These 3 waves shows movement in the heart. The bigger the wave the more electrical charge is in the heart.

The P wave- is the first wave on the trace. This shows the atrial systole. The wave is relatively small because the atria is not very strong.

The QRS wave- is also known as QRS complex. This is the largest wave on ...
