Hello,
1. You measure in the distance in mm from from one R wave to the next R wave.
2. Then multiply that number by 0.04 (at a normal chart speed of 25mm/sec each mm = 0.04 sec). Answer = R-R interval in seconds.
3. Divide 60 by the answer to 2. (60 seconds in a minute)
Answer = HR in bpm
Hope this helps :)
Hi,
So the above method is fine if the rate is regular (though I prefer to divide the 300 by the R-R interval), but to determine the rate in atrial fibrillation:
1. Count out 6 seconds (ie 30 big squares)
2. Count the number or QRS complexes in that period
3. Times the number of QRS complexes by 10.

What is the difference between heart rate and ventricular rate?
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.
Is there a heart rate calculator for running?
I think what you are looking for is a heart rate MONITOR. You calculate what your target heart rate should be using a formula then the monitor helps you keep track of your heart rate.

How best to cure arterial fibrillation developed recently?
Atrial fibrillation can be treated with medication to control the heart rate and thin the blood to reduce the risk of blood clot, heart attack, or stroke. Invasive procedures to treat atrial fibrillation include an ablation or, in extreme cases, the implantation of a pacemaker.

What is the medical term meaning the number of times a minute the heart beat is felt on the arterial wall?
The pulse rate is the number of times you can feel the heart beat.99You are descibing the pulse, or heart rate.
What determines the rate of blood flow?
The rate of blood flow is determined by factors such as the heart rate, the contractility of the heart muscle, blood pressure, the diameter of blood vessels, and the viscosity of blood. These factors work together to regulate the amount of blood that is pumped by the heart and the speed at which it travels through the circulatory system.

How do you calculate intensity?
John is a 30-years-old man with resting heart rate 72 who wishes to train 80% of thee heart rate reserve, how to calculate his target heart rate. Maximum Heart Rate=220-age=220-30=190 Heart Rate Reserve=190-72=118 Target Heart Reserve=Heart Rest Reserve*training intensity%+Resting Heart Rate

What Conditions affect mean arterial pressure?
Some conditions affecting mean arterial pressure, or MAP, blood pressure, heart rate, resistance to blood flow in the vessels, and cardiac output which is the volume of blood pumped out by the heart. Increasing or decreasing any of the can change your mean arterial pressure and cause consequences to the organs in the body.
In which type of bleeding is blood less likely to clot?
An arterial bleed, because the blood is flowing at a high rate of speed/pressure.
