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: Prevalence measures
Explanation:
The primary method that is used to measure the existence of states of a particular health or illness with regards to a population at a given time period is referred to as prevalence measure.
The prevalence measures simply refers to the proportion of individuals that have a particular disease at a particular period of time in a population.
Answer:
The correct answer is option E. only water-soluble hormones use second messengers.
Explanation:
Water soluble hormones can not diffuse through cell membranes as only lipid soluble molecules can pass through the cell membranes and these hormons are not lipid soluble molecules,
These water hormones are usually glycoproteins, peptide and catecholamnies such as TSH, FSH, LH and insulin. these hormones need second messengers because there receptors are present on the plasma membrane.
Thus, the correct answer is option - e. only water-soluble hormones use second messengers.
Denia in medical terms means: Pain, the feeling of pain
Hope that helped!
Answer: The total cholesterol is 199
Explanation:
Total cholesterol = LDL + HDL + Triglycerides
= 77 + 62 + 60
= 199.
As the patients doctor, I'd advise that the patient makes life style changes as they are approaching total cholesterol of 200 which is borderline high. Life style changes will include diet changes especially.
