You need to feel the pulse within your wrist or your neck. You could also buy a heart rate monitor. A normal heart rate is between 60-100 BPM.

QTcF relates to the Fridericia Correction Formula used in cardiology. To calculate the QTcF you apply the principle of QTcF = QT/Cube root (RR).
Because You can see the world from your home window that way we can do anything from Microsoft Windows Pallavan (RR GATES)
the velocity will be velocity divided by square root of 2
Green Acres was a television situation comedy starring mainly Eddie Albert and Eva Gabor with various sub-actors ( local merchants, etc) the farmer Mr. Zifful and his pig, Arnold,. and so on. it is not even clear whether Green Acres was the name of the farm, or of the surrounding community, known also as Hooterville. Hooterville also figured in the sit com Petticoat Junction, allegedly set in the same town with an RR background.

During exercise an increase in heart rate corresponds to a shortening of the cardiac cycle (RR interval decreases). Most of this shortening occurs in the TP interval. The QT interval also shortens, but only slightly. then the interval shortens as the heart rate increases.
RR interval 795 QRS interval 140 What is PR interval??
(QT/ RR^(1/3))*10
Use the Bazett's formula; which is the pt's QT intervaldivided by the square root of the RR interval. QTc should be less than 440msecs.
An RR interval is represented in milliseconds. Thus, to report the RR interval in seconds, simplay divide the value by 1000. e.g. RR interval of 876 divide by 1000 = 876/1000 = 0.876
To calculate tidal volume (TV) from gas volume and respiratory rate (RR), you would divide the gas volume by the respiratory rate. The formula is TV = Gas Volume / RR. This calculation gives you the average volume of air moved in and out of the lungs with each breath.
The RR interval of ECG vary during normal respiration because of the sinus arrhythmia.
Respiratory RateRR most often stands for respiratory rate, one of the vital signs.
If the RR of 1.5 is in seconds, it is outside the normal range of 0.6 - 1 second
