Two hormones that affect heart rate are epinephrine and norepinephrine. Both are actively involved with the body's stress response system. These hormones cause the body to increase heart rate so that oxygenated blood can reach muscles faster to promote more muscle strength and endurance.

Why is there a delay in the heart rate for 10 to 15 seconds after adrenaline has been produced before the heart rate increases?
Adrenaline is a hormone. Hormones are chemicals which travel via the blood stream to reach their targets. A hormone may have one or more than one targets. Since they are carried by the blood, the response (in this case the increased heart rate) is initiated when the blood carrying the hormone gets to the target cells, hence the delay.
What hormone increases heart rate and force of contraction?
Cardiac output is defined by the equation HR (heart rate) x SV (stroke volume). Anything that increases either of these will increase the cardiac output. Increasing heart rate: exercise, anxiety, caffeine, amphetamines, cocaine, other medications Increasing stroke volume: certain medications (digoxin, etc), lower heart rates
