The test subject repeatedly steps onto and off of a platform in a cycle of two seconds. [a] The height of the platform is 20 inches or 51 centimetres for men and 16 inches or 41 centimetres for women.

Aortic valve area calculation. In cardiology, aortic valve area calculation is an indirect method of determining the area of the aortic valve of the heart.

The sinoatrial node (also known as the sinuatrial node, SA node or sinus node) is an oval shaped region of special cardiac muscle in the upper back wall of the right atrium made up of cells known as pacemaker cells. The sinus node is approximately 15 mm long, 3 mm wide, and 1 mm thick, located directly below and to the side of the superior vena ...
Heart rate is the frequency of the heartbeat measured by the number of contractions of the heart per minute ( beats per minute, or bpm). The heart rate varies according to the body's physical needs, including the need to absorb oxygen and excrete carbon dioxide. It is also modulated by numerous factors, including (but not limited to) genetics ...
The units for the Heart Rate are beats per minute and for the Blood Pressure mmHg. Rate pressure product is a measure of the stress put on the cardiac muscle based on the number of times it needs to beat per minute (HR) and the arterial blood pressure that it is pumping against (SBP). It will be a direct indication of the energy demand of the ...
A slow heart rate of 60 or less beats per minute is defined as bradycardia. A fast heart rate of more than 100 beats per minute is defined as tachycardia. An arrythmia is defined as one that is not physiological such as the lowered heart rate that a trained athlete may naturally have developed; the resting heart rates may be less than 60 bpm.
