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).

hey! i would love to help..
Explanation:
are there any options? if so, i need them! please and thank you!
A small number of possible diagnoses and treatment options are described as medical decision-making that is: Straightforward.
Medical Decision Making :
Medical Decision Making refers to the complexity of establishing a diagnosis and/or selecting a management option by measuring the amount and/or complexity of medical records, diagnostic tests, the possibility of serious consequences, morbidity and/or mortality, as well as comorbidities, related with the patient's presenting problem(s), the diagnostic procedure(s).
According to Centers for Medicare & Medicaid Services , the levels of E/M services acknowledge four types of Medical Decision Making:
- Straightforward
- Low complexity
- Moderate complexity
- High complexity
