Assess lung function
Monitor oxygen levels
Record cardiac conduction
Measure blood pressure
Answer explanation

What defines a sinus rhythm in ECG analysis?
QRS up in I and down in aVF
Variable PR interval
P wave is negative in lead I, II
Each P wave is followed by QRS

How is the ST segment interpreted in ECG analysis?
Represents ventricular depolarization
Indicates atrial repolarization
Reflects ventricular repolarization
Measures atrial depolarization
Answer explanation
The ST segment in ECG analysis reflects ventricular repolarization, not atrial depolarization or other cardiac events.

What does the T wave signify in an ECG reading?
Represents atrial repolarization
Indicates ventricular depolarization
Reflects atrial depolarization
Measures ventricular repolarization
Answer explanation
The T wave in an ECG reading measures ventricular repolarization, indicating the recovery phase of the ventricles.
