The "R" is the greatest deflection from the baseline on the ECG. The R is part of the QRS complex. This complex represents ventricular depolarization in the heart.
The T wave is positive in an ECG due to the direction and charge. This positive deflection occurs after each QRS complex.
QRS in the context of cardiovascular health has reference to the electrical pattern of the heart. This is readily seen on an ECG (electrocardiogram). The Q wave is the first downward deflection after a P wave, the R wave is the first upward deflection following a P wave, and the S wave is the downward deflection following the R wave. Taken together the QRS complex represents the electrical activity of the heart during systole: the phase of the heart during which ventricular emptying occurs.
More cells depolarize during this QRS complex(ventricular contraction). The reason is because the muscle mass of the atria is small compared with that of the ventricles. The ventricles have a larger muscle mass. Therfore the electrical impulses within the atria are shorter and are less. The ventricles are larger so there is a larger deflection of the ECG when the ventricles are depolarised this is called the QRS complex
PR (Pulse Rate) intervals are measured by using the gap between the beginning of the P wave (the excitation of the atria) and the beginning of the QRS , a typical deflection seen on an ECG (Electrocardiogram).

QRS Records was created in 1928.
Nothing, they are equivalent.
Strain energy (1/2 * Force * deflection) = impact energy (potential energy) (mass * gravitational constant * [height+deflection] ) 0.5*F*d = m*g*(h+d) F is force, d is deflection, m is mass, g is gravitational constant, h is drop height.

"QRS" generally means to send messages slower.
