What is rhythm in Figure 8?

• Sinus rhythm

• Junctional rhythm

• Atrial fibrillation

• atrial tachycardia

The heart rate in figure 8 is closet to:

• 50

• 75

• 100

• 125

Treatment for the rhythm in Figure 8 could include ALL BUT:

• Atropine

• Oxygen

• Electrical shock to the heart

• No treatment

The rhythm in Figure 9 is?

• Sinus rhythm

• Accelerated Junctional rhythm

• Atrial fibrillation

• Junctional tachycardia

In figure 9, the P waves are:

• upright, rounded, preceding the QRS.

• Inverted preceding the QRS

• Not visible

• Inverted following the QRS

The rhythm in figure 9 originated where?

• In the sinus node

• High up in the AV junction

• In the atrium

• Low down in the AV junction

The AV node is located in the?

• Left Atrium

• Right Atrium

• Right Ventricle

• Left Ventricle

Junctional tachycardia without visible P waves is best called

• Sinus Tachycardia

• SVT

• Atrial tachycardia

• PJC's

Junctional tachycardia is associated with which medication toxicity?

• Quinidine

• Digitalis

• Atropine

• Oxygen

Treatment for occasional PJC's is to

• Give atropine to speed the heart rate up.

• Give digitalis to slow the heart rate down

• Shock the heart out of the rhythm

• Treat the cause.
