Really what happens is your main body temperature lowers so your heart pumps faster and faster resulting in it shutting down.this is called hyperthermia.
You will feel weak because blood will not be flowing in your veins the way it should be and your heart will be pumping slower.
Vagus nerve stimulation can decrease heart rate by inhibiting the electrical activity of the heart's pacemaker cells, which are responsible for setting the heart rate. This can be therapeutic in conditions where a slower heart rate is beneficial, such as in certain cases of epilepsy or heart failure.
Resting heart rate goes down (maximum stays the same).
Sinus bradycardia is a condition where the heart beats slower than normal due to the sinus node, the heart's natural pacemaker, sending electrical signals at a slower rate. It is typically considered normal in well-trained athletes or during sleep, but can also be present in some medical conditions or as a side effect of certain medications. Treatment is usually unnecessary unless it causes symptoms or complications.
The velocity of blood flow varies depending on where it is in the circulatory system. It is fastest in arteries due to the pressure generated by the heart, and slower in capillaries where exchange of nutrients and waste occurs. The velocity then increases again in veins as blood returns to the heart.
Runners have a slower heart rate because the act of running makes the heart stronger... with a stronger heart stroke volume is increased so the heart does not need to beat as much to fulfill its transportation needs
50 heartbeats
the cooler the frog the slower the heart rate, the warmer the faster
Its relaxing so your heart is resting in other words.
slow

They do not do anything to raise their heart rate.

Jane Waters died on September 29, 2011, in Pittsburgh, Pennsylvania, USA of heart attack.
The heart beats faster due to your bodies response to the stress.
If you fix your eyes on the color red, your heart will beat faster.
Around 300 bpm when running
