On an EKG strip a nurse determines that a patient's heart is beating 5 times every 4.5 seconds.
Calculate the time for each heart beat.
I don't really understand what the question is asking for? Is it looking for how often the beats will occur (4.5/5)= 0.9 seconds??? Or is it looking for
0.9sec= beat 1
1.8sec= beat 2
2.7sec= beat 3
3.6sec= beat 4
4.5sec= beat 5
Calculate the patient's heart rate in beats/min. Hint: divide 60 by the time per beat.
Beat 1= 67 beats/min
Beat 2= 33 beats/min
Beat 3= 22 beats/min
Beat 4= 17 beats/min
Beat 5= 13 beats/min
Thank You!
5/4.5 = 10/9 = x/60
Solve for x.
To calculate the time for each heart beat, you can divide the total time (4.5 seconds) by the number of heart beats (5). This gives you 0.9 seconds per beat.
For the calculation of the patient's heart rate in beats per minute, you need to convert the time per beat (0.9 seconds) to minutes. Since there are 60 seconds in a minute, you divide 60 by 0.9. This gives you approximately 66.67 beats per minute.
It seems like you are on the right track with your calculations:
Beat 1: 0.9 seconds = 60/0.9 = 66.67 beats/min
Beat 2: 1.8 seconds = 60/1.8 = 33.33 beats/min
Beat 3: 2.7 seconds = 60/2.7 = 22.22 beats/min
Beat 4: 3.6 seconds = 60/3.6 = 16.67 beats/min
Beat 5: 4.5 seconds = 60/4.5 = 13.33 beats/min
Therefore, the patient's heart rate for each beat is approximately:
Beat 1: 67 beats per minute
Beat 2: 33 beats per minute
Beat 3: 22 beats per minute
Beat 4: 17 beats per minute
Beat 5: 13 beats per minute
You're welcome! Let me know if there's anything else I can help with.
To calculate the time for each heartbeat, you need to divide the total time (4.5 seconds) by the number of beats (5).
4.5 seconds / 5 beats = 0.9 seconds per beat
So, each heartbeat occurs every 0.9 seconds.
To calculate the patient's heart rate in beats per minute, you need to divide 60 seconds (1 minute) by the time per beat (0.9 seconds).
60 seconds / 0.9 seconds per beat = 66.67 beats per minute
Therefore, the patient's heart rate is approximately 66.67 beats per minute.
