Answer: 70 to 120 seconds is the usual amount of time for blood to clot without heparin. 180 to 240 seconds is the usual amount of time for blood to clot with heparin.
Explanation:
The term "chemotherapy" ("chemo") is frequently used to describe treatments for cancer.
<h3>
What is chemotherapy?</h3>
cancer medications function in the same way. The medications used in conventional or traditional chemotherapy are cytotoxic, which means they can destroy tumor cells.
Knowing how traditional or standard chemotherapy functions and what to anticipate can often help you get ready for treatment and make wise healthcare decisions if your treatment plan calls for it.
Drugs are used in chemotherapy to kill cancer cells. This particular cancer treatment prevents cancer cells from proliferating, dividing, and creating new cells.
Therefore, The term "chemotherapy" ("chemo") is frequently used to describe treatments for cancer.

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).
