The values obtained when taking blood pressure, such as 120/80,
Wittaler [7]

Answer:

The correct answer will be option B.

Explanation:

Blood pressure represents the pressure of the blood in the major arteries of the body.

This blood pressure increases in the arteries when the ventricle contracts to push the blood to the major artery by a mechanism called ventricular systole. This increased blood pressure number is known as systolic blood pressure which is usually 180 mm of Hg.

The blood pressure decrease in the artery due to ventricular diastole during which ventricles relaxes. This lower number of blood pressure is known as diastolic blood pressure which is 80 mm of Hg.

Thus, option B is the correct answer.

How to calculate the heart rate from the electrocardiogram ?​
Masja [62]

Answer:

ECG paper is a grid where time is measured along the horizontal axis.

Each small square is 1 mm in length and represents 0.04 seconds.

Each larger square is 5 mm in length and represents 0.2 seconds.

Voltage is measured along the vertical axis.

10 mm is equal to 1mV in voltage.

The diagram below illustrates the configuration of ECG graph paper and where to measure the components of the ECG wave form

Heart rate can be easily calculated from the ECG strip:

When the rhythm is regular, the heart rate is 300 divided by the number of large squares between the QRS complexes.

For example, if there are 4 large squares between regular QRS complexes, the heart rate is 75 (300/4=75).

The second method can be used with an irregular rhythm to estimate the rate. Count the number of R waves in a 6 second strip and multiply by 10.

For example, if there are 7 R waves in a 6 second strip, the heart rate is 70 (7x10=70).
