7. Transfer the values of the means from Tables 2 and 3 into Table 4 below Then calculate the amount each portion of the ECG changed with exercise. Table 4: Comparing ECG Before and After Exercise Time in seconds (s) Exercise Change Avorage 60 to 110 120 to 200 80 022 03s 007s QRS complex120 or less 058s 120 3s Q TInterv 310 to 410 255s 105 s 160 Varies Data Analysis Questions End of T to 452s 3 14s 8: Give the equation the computer uses to calculate BPM using AT. 9. Describe the relationship between AT and BPM. For instance, if AT gets shorter what happens to BPM? 10. In Table 4, when comparing "resting" to "exercise", which component of the ECG trace decreased the most? By how many s did this component shorten? 11. Does it make sense that the component you named in #10 shortened the most? Why or why not?

Explanation / Answer

ans 8..... equation computer use to calculate using BPM is

60 divided by difference in time

i.e 60/t

ans 9...as already written above

BPM =60/t

where BPM is beats per minute

if t gets shorter BPM will increase

ans 10...in table.4 as u can see the one that decreases the most is end of T to next R and change is by 0.233

ans 11..yes it do makes sense because in this event determine the event between two heart beats.which is determined by heart rate.in excerscise the heart rate increases and thus duration of contration decreases.which makes the biggest change in this region
