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).
Axial and appendicular.
Axial makes up the main axis of the body the head, neck and chest
Appendicular makes up parts of the human body that connects to the axial the limbs and appendages.
Answer:Depending on the size of the tear, recuperation might take anywhere from 4 to 6 months or longer. Most activities can be resumed after six months, although the rotator cuff can take up to a year to heal.

Answer:
It is a vision that is close to normal, if in the optometric revision improves with the use of the pinhole more than three lines, the problem may be of the refractory type; If this is not corrected, it can be concluded that there is a disease.
Answer:
Gold is primarily found as the pure, native metal. Sylvanite and calaverite are gold-bearing minerals. Gold is usually found embedded in quartz veins, or placer stream gravel.
