Question 1

Explain the benefits of a dual-chamber pacemaker.

Accepted Answer

The dual-chamber pacemaker stimulates the right atrium and right ventricle sequentially (stimulating first the atrium,then the ventricle),mimicking normal cardiac physiology and thus preserving the atrial contribution to ventricular filling (i.e.,atrial kick).

C)  a pacing lead with a single electrical pole at the distal tip of the pacing lead through which the stimulating pulse is delivered 
D)  the ability of a pacemaker to increase the pacing rate in response to physical activity or metabolic demand 
A)  the ability of a pacemaker to recognize and respond to intrinsic electrical activity 
B)  the minimum level of electrical current needed to consistently depolarize the myocardium 
C)  a pacing lead with a single electrical pole at the distal tip of the pacing lead through which the stimulating pulse is delivered 
D)  the ability of a pacemaker to increase the pacing rate in response to physical activity or metabolic demand B

Question 3

Question 4

In pacing,rate modulation refers to _____.

Accepted Answer

A)  the ability of a pacemaker to recognize and respond to intrinsic electrical activity
