TP interval
How does the autonomic nervous system respond during postural changes regarding heart rate?
Parasympathetic nervous system activation
During exercise, why does systolic pressure increase more than diastolic pressure?
Need to supply more blood to exercising muscles
What is the physiological response of the dive reflex on heart rate?
Decrease in heart rate for survival
What is the main cause of heart sounds heard during cardiac cycles?
Opening and closing of heart valves

Vessel dilation
What is the first sound you hear when measuring blood pressure with a stethoscope?
Systolic pressure
Why is systolic pressure typically higher than diastolic pressure?
Systolic pressure occurs when the heart first contracts
Which segment of an ECG tracing indicates ventricular depolarization?
