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).

<h3>What are primary health prevention?</h3>
Primary prevention entails taking action against a vulnerable group or individual. Primary prevention aims to stop a disease from ever developing. Healthy people are hence its intended audience. To stop a disease from developing in a susceptible person into a subclinical disease, it is frequently implemented activities that restrict risk exposure or boost the immune of those at risk.
Programs for health education, vaccinations, and physical and nutritional fitness activities are all forms of primary prevention that aim to promote health.
The first step in promoting health is to educate others about the dangers of smoking.
I understand the question you are looking for is this:

1. teaching a class on the dangers of smoking
2. encouraging clients to perform breast self-examinations
3. having a blood test for the human immunodeficiency virus
4. taking antimicrobials for a positive Mantoux test
