Chapter 7 - Introducing the Sinus Rhythm

External pacing is also referred to as ________ pacing.

• Anterior

• Transcutaneous

• Subcutaneous

• Supraventricular

The part of the conduction system that is located on the floor of the right atrium is the:

• AV node

• Bundle of His

• SA node

• Purkinje network

Which of the following terms indicates "fast"?

• Absent

• Tachy

• Paroxysmal

• Brady

The primary pacemaker cell of the heart is the:

• Purkinje network

• SA node

• AV node

• Bundle of His

The rhythm in which the SA node discharges impulses at a rate between 100 and 160 is called:

• Sinus

  Bradycardia

• Sinus

  Arrhythmia

• Sinus

  Tachycardia

• Normal

  Sinus

  Rhythm

The area of the conduction system that is defined as the "gatekeeper" to the ventricles is the:

• SA node

• Purkinje network

• AV node

• Bundle of His

All of the following are signs of cardiac compromise EXCEPT:

• Hypertension

• Pale, clammy skin

• Tachycardia

• Hypotension

When the sinus node fails to discharge, the absence of a PQRST interval is noted on the rhythm and is called:

• Sinus

  arrest

• Sinus

  dysrhythmia

• Sinus

  Rhythm

• Sinus

  Bradycardia

The part of the conduction system that is located in the septum and in the ventricles is the:

• AV node

• Bundle of His

• Purkinje network

• SA node

The irregular rhythm produced with the P to P intervals and the R to R intervals change with respirations is called:

• Sinus

  Arrhythmia

• Tachycardia

• Bradycardia

• Sinus

  Dysrhythmia
