First we need to note the current guidelines on hypertension. i d not specifically adhered to his in my practise and more data needs to emerge to be including this. Howver a practise changing update from AHA states, “ hypertension now defined as a blood pressure ≥130 mmHg systolic or ≥80 mmHg diastolic.”.
Many studies state that the correlation co- efficient which si the link of Heart Rate to Blood Pressure is not constant.
When resting, the adult human heart beats at about 70 bpm (males)
and 75 bpm (females), but this rate varies among people. The heart
rate increases when we are active or when we feel strong emotions.
The heart is first and foremost a pump. It pumps oxygenated blood
to the body to support the production of cellular energy. During
exercise, working muscles increase their cellular energy
requirements up to 100X. Generating more energy (ATP) requires
more oxygen delivery to the mitochondria. Therefore heart rate will increase (from 70bpmà200bpm ) to sustain work at a greater maximal intensity.
The most accurate resting heart rate per minute can be obtained by taking the radial pulse once you wake up in early morning. A WHIO report carries the table for accessing this optimal value as under:
