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:
The correct answer is option C. thymus.
Explanation:
Lymph nodules are small groups of lymphoid tissue present in the loose under the wet epithelial membranes such as the digestive system, urinary bladder, and respiratory system.
The thymus does not contain lymph nodules like other lymphatic organs such as spleen, tonsils and lymph node. However, small lymphocytes known as thymocytes are grouped together in the cortex and epithelial reticular cells can appear like nodules in the medulla.
Thus, the correct answer is option C. thymus.
It is known as menorrhagia
