Question

b) Vani is an athlete whose heart rate is 140 beats per minute during practice. What is the approximate number of spikes that would be shown in her ECG report? (i) 35 (ii) 14 (iii) 7 (iv) 10​

Answer 1

35 is the answer

Explanation:

35 is the answer

Answer 2

The number of spikes in Vani's ECG will be 35

• The spikes that are seen in an ECG indicate 1 heartbeat. In athletes, the resting heart rate is much less as compared to non-athletes and can be below 40.
• Since Vani is an athlete her resting heart rate will be below 40 and could be around 35-40.
• Hence the number of spikes observed in her ECG will also be 35-40.

Thus, the approximate number of spikes that would be shown in her ECG report will be (Option i) 35.
