Systematic approach to ECG interpretation Flashcards
3 steps for interpretation
1- glance at ECG- am I instinctively concerned
2- what is the heart rate and interval durations
3- what is the rhythm
Measuring HR on ECG if regular rhythm
Rate= 300/ R-R interval in large squares
Measuring HR on ECG if irregular or regular
30 large boxes= 6 secs
-count number of QRS complexes in 30 squares
-times by 10 for 60 seconds
What are we looking for when diagnosing rhythm
-if its regular, irregular, regularly irregular or irregularly irregular
- 1:1 ratio of P waves to QRS complexes
- what are the P-R intervals and QRS interval
Question 2 HR and interval duration things we do
-count 30 large boxes (6 secs)
-How many qrs complexes inside
-times by 10
-what is the PR/ QRS interval
