What is normal sinus rhythm?

What can cause the stylus on EKG paper to move strongly up and down?

• Consistent heart rhythm

• Patient movement dislodging an electrode

• Proper electrode placement

• Regular heart rate

What does the P wave represent in an EKG?

• Ventricular depolarization

• Atrial depolarization

• Heart rate

• QRS complex

What is a characteristic of a regularly irregular rhythm?

• No pattern at all

• Consistent, noticeable irregular pattern

• Exact same distance apart

• Random spacing of waveforms

What is the importance of the P wave's location in an EKG?

• It reflects the rhythm

• It is crucial for overall interpretation

• It determines heart rate

• It shows ventricular depolarization

What is the normal range for the QRS interval on an EKG?

• 0.01 to 0.05 seconds

• 0.04 to 0.10 seconds

• 0.10 to 0.20 seconds

• 0.20 to 0.30 seconds

What could variances in the shape of the P wave indicate?

• Electrical conduction pathway abnormalities

• Normal heart function

• Increased heart rate

• Decreased heart rate

What is the significance of the QRS complex width?

• It indicates heart rate

• It indicates ventricular dysfunction

• It indicates atrial dysfunction

• It indicates blood pressure

What does the P-P interval represent?

• Time between ventricular depolarization cycles

• Time between atrial depolarization cycles

• Time between ventricular repolarization cycles

• Time between atrial repolarization cycles

What is the ending point of the ST segment?

• Beginning of the P wave

• Beginning of the Q wave

• Beginning of the R wave

• Beginning of the T wave

Where do T waves typically peak in an EKG?

• At the beginning of the wave

• At the middle of the wave

• At the end of the wave

• At the baseline
