Is hypothesis refute or support to my results i found on what will happen holding your breath 5 minutes will increase or decrease?

increase heartbeat

Explanation:

Just as during exercise, holding your breath for 5 Minutes will increase levels of CO2 in your BLOOD.

Then, the body tries to wash out the excess CARBON DIOXIDE while providing FRESH OXYGEN. Your heartbeat rate will also INCREASE in order to pump your blood and properly "ventilate" your muscles.

So, holding your breath for 5 minutes will INCREASE heartbeat.
