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).
Answer:
an idiom
Explanation:
not meaning the literal thing you said,
just as those who die do not actually kick a bucket or calendar, it is a phrase to use that means someone has died
