Question 1

Calculating heart rate involves counting

Answer 1

Qrs complexes. Beats per min.

Question 2

Atrial rate is found by

Answer 2

Counting the p waves on the strip

Question 3

All 3 methods for heart relate use 6 to 12 sec strips

Answer 3

3 are.
Six second strip method
Memory method
Little block method

Question 4

6 sec strip

Answer 4

Least accurate, count the number of theQrs on the strip and multiply by 10. This is the mean rate

Question 5

Fastest method memory method

Answer 5

big blocks between Qrs divided by 300. Or count blocks. 300, 150, 100’75, 60,50,43,37,33,30

Question 6

Little block method

Answer 6

Count number of little blocks between Qrs complexes and divide by 1500

Question 7

Rhythm regularity is

Answer 7

Constancy of QRS complexes

Question 8

Compare R and R intervals to determine

Answer 8

Regularity of a rhythm. Count little blocks between QRs complexes

Question 9

3 types of regularity

Answer 9

Regular
Regular but interrupted
Irregular

Question 10

Regular is

Answer 10

Rhythms. Vary by 1 to 2 blocks

Question 11

Regular but interrupted is

Answer 11

Interrupted by. Premature beats or pauses

Question 12

Irregular rhythms are

Answer 12

R and r intervals vary, not just beats but chaotic

Question 13

Regular rhythms calculate heart rate by

Answer 13

Choosing 2 QRS complexes and use the little block method

Question 14

For irregular rhythms use the

Answer 14

6 second strip for mean rate, then do heart rate for the little block method

Question 15

Regular but interrupted

Answer 15

Use the little block method on uninterrupted part of the strip

Question 16

If abrupt change in strip, check pt

Answer 16

aAlways

Question 17

Dyers rhythmical

Answer 17

Abnormal rhythms. In any pacemaker

Question 18

5 steps. To rhythm interpretation,

Answer 18

1. Are there Qrs complexes, same shape or varies
2. Rhythm regular, regular but interrupted, or irregular. Compare r and r
   Heart rate. Greater then 100(tachycardia)
   Less than 60(bradycardia)
   Any p waves, followed by Qrs? Shape, size
3. Pr and Qrs intervals normal or short or long

Question 19

Sinus node

Answer 19

Hearts pacemaker

Question 20

Normal is. Sinus rhythm,

Answer 20

Narrow Qrs, / regular space/ 60/100 heart rate/ p waves married to Qrs. And or interval 0.12 to 0.20. Qrs less then o.12
