Is 66 a good heart rate?
The normal heart rate for an adult is between 60 and 101. Thus, a heart rate of 66 - in my opinion - is very good.The normal heart rate for an adult is between 60 and 101.

What does a pacemaker control in the heart?
A pacemaker sends electrical shocks to the heart to beat it at a particular speed. It pulsates the heart at a set rate (eg. 60bpm) to help those who are have a slower than normal heartbeat.
What sends impulses from the accelerator center to increase heart rate?
Sympathetic
What creates heart rate?
Heart rate is simply the number of times that the heart beats per minute. This is generated by the "pacemaker" of the body which is the signal sent from the brain to the heart's sinoatrial (SA) node. This causes the initiation of contraction of the cardiac muscle which spreads across the heart to contract the atria and ventricles in a rhythmic fashion. The number of times this signal is sent from the brain to the heart gives the heart rate.

What is the primary brainstem structure that controls heart rate?
medulla oblongata
What is the primary brain stem structure that controls the heart rate?
medulla oblongata!
What is a stimulus and how does it affect the nervous system?
A stimulus is a signal that triggers a response in the body. When a stimulus is detected by sensory receptors, it sends signals to the nervous system. The nervous system then processes this information and coordinates a response, which can involve actions such as movement, secretion of hormones, or changes in heart rate.
What causes a fast heart rate?
exercise, drugs, excitement, health problems,
Does the heart rate change as you listen to music?
Absolutely. Well, your heart rate will speed up when you get excited so when you listen to a really good song and you get pumped, you brain sends signals to your heart. therefore it will speed your heart up, so .. really it more music over brain, brain over heart, heart over pulse. I hope that helps. =)
Circuit diagram for heart beat counter?
A heart beat counter circuit typically consists of a heart rate sensor connected to a microcontroller (such as Arduino) which processes the sensor data and displays the heart rate on a digital display (such as an LCD screen). The heart rate sensor measures the electrical activity of the heart and converts it into a signal that the microcontroller can interpret. The microcontroller then calculates the heart rate based on the sensor data and displays it on the screen.
How has energy saved lives?
When doctors use a heart defibrillator it sends energy currents through the body and helps restore a normal heart rate or will send currents to the heart to get it working again thus preventing death.
What is the second control system for the speed of the heart beat?
I don't quite understand your question. The sympathetic nervous system controls your heart-rate. If you go on a deeper level, the "pacemaker" controls the heartbeat. It's also called the Sinuartrial Node. There's also a node called the Atrioventricular Node, and it's function is to be a relay point for the electrical signal from the Sinuartial node, that later sends it out to the other parts of the heart.
