ECG Reading Practice

Identify the heart rhythm.

• Second degree heart block I

• Second degree heart block II

• First degree heart block

• Atrial fibrillation

Identify the heart rhythm.

• Normal sinus rhythm

• Sinus Tachycardia

• Sinus Bradycardia

• First degree heart block

Identify the heart rhythm.

• Atrial fibrillation

• Complete heart block

• Normal sinus rhythm

• Atrial flutter

TRUE OR FALSE: You can measure the PR interval in atrial flutter while you cannot do so in atrial fibrillation.

• True
• False

Your patient is pulseless with atrial flutter. The next step is to:

• Start chest compressions
• Administer epinephrine stat

• Perform defibrillation
• Perform cardioversion

TRUE OR FALSE: P waves are measurable in ventricular tachycardia.

• True
• False
• Depends on the severity of the tachycardia
• Only in certain types of ventricular tachycardia

Identify the HR and rhythm.

• 50 bpm, Second degree HB

• 50 bpm, First degree HB

• 50 bpm, SB

• 50 bpm, NSR
