Electrocardiogram Flashcards
Identify the waveforms found in a normal ECG.
P wave
QRS complex
T wave
ST segment
PR interval
In an ECG reading, which wave represents depolarization of the atrium?
P wave
In an ECG reading, which complex represents depolarization of the ventricle?
QRS complex
What does the PR interval represent?
The time required for the impulse to travel from the atria through the AV node.
If the U wave is most prominent, what condition might the nurse suspect?
Hypokalemia
Describe the calculation of the heart rate using an ECG rhythm strip.
Count the number of RR intervals int he 30 large squares and multiply by 10 to determine the heart rate for 1 minute.
What is the most important assessment data for the nurse to obtain in a client with an arrhythmia?
Ability of the client to tolerate the arrhythmia.
