BART (Basic Arrhythmia Recognition and Treatment) notes Flashcards
What is an analogy for the AV node function? (BART)
Like a stoplight on the freeway ramp
What is the AV junction? (BART)
AV node and the Bundle of His
What is the PR segment? (BART)
- Distance between the end of p wave and beginning of QRS complex
- Represents the delay of the AV node
What is the PR interval? (BART)
- The time between the beginning of the p wave and the first deflection of the QRS, which may be positive or negative
- P wave + PR segment
What is the PR interval? (BART)
- The time between the beginning of the p wave and the first deflection of the QRS, which may be positive or negative
- P wave + PR segment
What is a normal PR interval? (BART)
- 12 - 0.20 seconds
- 12 = 3 small boxes
- 20 = 1 large box, 5 small boxes
What is a normal QRS complex duration? (BART)
Less than or equal to 0.12 seconds (less than 3 small boxes)
What is the J point? (BART)
Junction where the QRS complex and the ST segment meet
What is the J point? (BART)
Junction where the QRS complex and the ST segment meet
What is the ST segment? (BART)
J point to beginning of T wave
What is a normal QT interval? (BART)
- 27 - 0.43 seconds
0. 44 = 11 boxes
What is the QTc (QT interval corrected)? (BART)
- QT interval will vary with age, gender, and HR
2. QTc = QT/square root of R-R interval
What are abnormal QTc values? (BART)
> 0.44 seconds in males
>0.43 seconds in females
What are abnormal QTc values? (BART)
> 0.44 seconds in males
>0.43 seconds in females
How many large boxes equals 6 seconds? (BART)
30 large boxes
