Pacing Modes
What mode paces the ventricle, senses the ventricle, and responds to sensing with inhibition?
VVI
A lead fracture causes lead impedance to increase or decrease?
Increase
The VT zone uses what type of counter?
Consecutive
What percent of patients develop an infection after device implantation?
1-4%
What mode paces the atrium and ventricle, senses the atrium and ventricle, and responds to sensing with tracking and inhibition?
DDD
If a pacemaker is undersensing, should you increase or decrease the sensitivity value (mV).
Decrease (make it more sensitive)
What is the average longevity for Cobalt XT dual chamber ICD?
11.9 years
What is the range of margin loss for a hospital to treat a device related infection?
$6,000-$31,000
What mode do is commonly program for patients with complete heart block but normal sinus node function?
DDD
What is the average longevity for Azure XT dual chamber pacemaker?
13.7 years
What changes occur when you place a magnet over an ICD?

About 9 weeks
What mode is commonly programmed with patients with single chamber pacemakers that have permanent AF with slow ventricular response?
VVIR
Reactive ATP delivers what therapy to terminate AT/AF?
Atrial ATP
