On an ECG the heart rate will match both ventricular rate and atrial rate if the heart is normal. If people have atrial fibrilation then the ventricular rate will be used on the ECG to work out the rate of the ventricular contraction and vice-versa with ventricular fibrilation. Usually both atrial and ventricular rates match so if the atria contracts at 70 BPM the ventricles will beat at 70 BPM. It is possible for the ECG machine to work out atrial or ventricular rate if needs be. Usually, however, if the ECG machine just displays heart rate then both ventricular and atrial rates match.
Heart rate is how many times the heart contracts per minute while the stroke volume is the amount of blood ejected per beat.
Cardiac output is measured by the product of both (Heart rate x stroke volume).

What effect does atropine have on heart rate?
Ventricular fibrillation, and supraventricular or ventricular tachycardia.
How do you count ventricular rate of heart?
Place the stethoscope over the heart (left side of the chest) and count the heart beat for a full minute.
Can it kill if your heart rate goes up when you are sick?
If your heart rate increases because of adrenaline (related to your emotional state) that is unlikely to kill you. There are some conditions, particularly ventricular fibrillation, in which increased heart rate can kill you, but in most forms of sickness, increased heart rate is not dangerous.
What is the difference between blood pressure and heart rate?
Blood pressure is the pressure exerted on the wall of arteries and veins. Heart rate is the BPM or beats per minute.
What can decrease the cardiac output?
The cardiac output can be decreased by decreasing the force of contraction of the ventricular myocardium and decreasing the heart rate.
What effect does atropine have on heart rate?
Ventricular fibrillation, and supraventricular or ventricular tachycardia.
When heart rate is increased the time of ventricular filling is?
. . . decreased.
What does nonsustained ventricular tachycardia mean?
Nonsustained ventricular tachycardia is elevated heart rate originating in the ventricles that stops on its own.
What factors can increase myocardial oxygen demand?
Heart rate and ventricular wall tension
What is the physiology of ventricular tachycardia?
A rapid heart rate can originate in either the left or right ventricle. Ventricular tachycardia which lasts more than 30 seconds is referred to as sustained ventricular tachycardia
What does the difference between a persons resting and Target rate reflect?
The difference between a person's resting and target heart rate reflects the amount of work the heart must do to meet the increased demands of the body when exercising.
How do you count ventricular rate of heart?
Place the stethoscope over the heart (left side of the chest) and count the heart beat for a full minute.
What is the Difference between junctional tachycardia and accelerated junctional rhythm?
An accelerated junctional rhythm has a heart rate between 60 and 100. Meanwhile, a junctional tachycardia has a heart rate >100.
How do you determine Morning Resting Heart Rate?
Its the difference between your systolic and diastolic readiing.
Can it kill if your heart rate goes up when you are sick?
If your heart rate increases because of adrenaline (related to your emotional state) that is unlikely to kill you. There are some conditions, particularly ventricular fibrillation, in which increased heart rate can kill you, but in most forms of sickness, increased heart rate is not dangerous.
