Question 6

What kind of pacemaker is described?

• Has at least one right ventricular lead, one left ventricular lead and may have a right atrial lead as well.
• The left ventricular lead traverses the coronary sinus into a posterior or lateral cardiac vein

Question 14

What device is described?

• Capable of generating a large amount of electrical energy in a single output used to defibrillate the heart.

Answer 19

Question 20

What pacemaker is described?

• Has one lead that paces either the right ventricle or right atrium.
• Most commonly, this lead is placed in the apex of the right ventricle
• Used to pace the heart when there is a problem with the conduction pathways.
