EKGs

What do you have to have for it to be considered a Sinus Rhythm?

• P wave

• S Wave

• Q wave

• R wave

What does a rhythm have to have for it to be considered SVT?

• Over 150 BPM

• No P waves

• Irregular

• No T wave

Match the numbered features of this electrocardiograph with the appropriate name.

• 3

• QRS complex

• 1

• T wave

• 2

• P wave

What conduction system fires an impulse in order for the atria to contract?

• SA node

• AV node

• Bundle of his

• Purkinje Fibers

Match the Intrinsic Rates with their location

• 20-40 BPM

• Atrial Muscle

• 60-80 BPM

• A-V Node

• 60-100 BMP

• Ventricular Muscle

• 40-60 BPM

• Sinus Node

Where is the bundle of His ?

What heart rhythm has a regular rhythm, abnormal or absent P way with a narrow QRS?

• Sinus bradycardia
• Junctional rhythm
• Atrial fibrillation
• Ventricular tachycardia

Answer explanation

Abnormal or absent P waves, Narrow QRS

HR 40-60: Junctional Rhythm

HR >60-100: Accelerated Junctional Rhythm

HR > 100: Junctional Tachycardia

What two rhythms are considered Supraventricular arrhythmias?

• Atrial Fibrillation and Atrial Flutter
• Sinus Bradycardia and Sinus Tachycardia
• Ventricular Tachycardia and Ventricular Fibrillation
• Premature Atrial Contractions and Premature Ventricular Contractions

Conduction is slowest through the AV node, how many seconds is the signal?

• ~0.12

• ~0.19

• ~0.07

• ~0.22

Label the following.

NSR with PACs

Answer explanation

Has one distinct Finding-

All the p waves vary in size, shape, or can even be absent.
