To determine the type of ECG rhythm the patient has, the ECG tech is required to evaluate what components of the ECG?
|
1. regularity
2. rate 3. PR Interval |
|
|
Regularity of the rhythm is determined by evaluating the regular/irregular patterns of what complexes?
|
P-P
R-R |
|
|
If the ECG tech can't identify the an R wave on the ECG tracing, which waves you would use to determine regularity of ventricles?
|
Q and S wave junction.
|
|
|
What method do you use to best calculate the heart rate?
|
Count the No# of small boxes between the R-R waves and divide that No# into 1500.
|
|
|
When you analyze the shape of the P wave to see if they are all the same shape is to determine?
|
Atrial contraction.
|
|
|
Measuring the PR interval requires that you measure?
|
beginning of the P wave to the beginning of the QRS complex.
|
|
|
Normal range for the PR Interval is?
|
.12 - .20 seconds
|
|
|
QRS measurement is to determine the time it takes for?
|
Ventricular contraction.
|
|
|
Sinus bradycardia has the same criteria as Sinus Rhythm with the only difference being?
|
the heart rate is slower.
|
|
|
Atrioventricular pacing is similar to what characteristics of the heart?
|
normal conduction pathway.
