What is the effect of sympathetic stimulation on the heart?

Step 1: Understand that the sympathetic nervous system is part of the body's response system.
Step 2: Know that sympathetic stimulation happens during stressful situations, like danger or excitement.
Step 3: Recognize that when the sympathetic nervous system is activated, it sends signals to the heart.
Step 4: These signals cause the heart to beat faster, which is called an increased heart rate.
Step 5: The signals also make the heart muscles contract more strongly, which is known as increased contractility.
Step 6: This overall effect prepares the body for quick action, often referred to as the 'fight or flight' response.
