Heart Rhythm Quiz

What is the term for a heart rhythm where QRS complexes occur in a pattern that looks the same each time and repeats with consistent timing?

• Rhythm Regularity

• Arrhythmia

• Tachycardia

• Bradycardia

What does the P-P interval measure?

• The amount of time between ventricular depolarization cycles

• The amount of time between atrial depolarization cycles

• The amount of time between heartbeats

• The amount of time between respiratory cycles

What is the significance of consistently similar P-P intervals?

• Irregular atrial rhythm

• Regular atrial rhythm

• Increased heart rate

• Decreased heart rate

How should P-P intervals occur in relation to respiration?

• With large variations

• With no variations

• With only small variations

• With decreasing variations

What is the R-R interval used to find?

• Atrial rhythm

• Ventricular rhythm

• Heart rate

• Blood pressure

What should the R-R intervals occur with?

• Large variations associated with respiration

• Irregular patterns

• Regularly with only small variations associated with respiration

• No variations at all

What does consistently similar R-R intervals indicate?

• Irregular ventricular rhythm

• Regular ventricular rhythm

• High blood pressure

• Low heart rate

If the R wave isn’t present, what should be used instead?

• P-P interval

• S-S interval

• Q-Q interval

• T-T interval

What is the normal variation range for R-R intervals?

• Up to 0.02 seconds

• Up to 0.04 seconds

• Up to 0.06 seconds

• Up to 0.08 seconds

What are ectopic beats?

• Extra heartbeats occurring just before a regular beat

• A type of regular heartbeat

• A condition causing the heart to stop

• A normal part of the heartbeat cycle
