1

what are the indications for a pacemaker? in bradycardic patients

patient has a slower than normal impulse formation of a symptomatic AV or ventricular conduction disturbance

2

what are the indications for a pacemaker? in tachycardic patients

patients have a tachydysrhythmic heart rate that cannot be controlled by medications
they need a biventricular pacemaker that is used to resynchronize the heart

3

what are the indications for a pacemaker for someone who is in advanced heart failure?

they have a biventricular pacemaker that resynchronizes the heart, this may include the ICD in patients

4

two pieces of a pacemaker

pulse generator (outside of heart that houses the batteries)
Leads (electrical wires that stimulate the heart)

5

temporary pace makers have a pulse generator that controls what?

rate
strength
sensitivity

6

rate

beats per minutes

7

strength

amount of electrical stimulus that is sent to the heart

8

sensitivity

the amount of intracardiac activity that needs to be sensed by the electrodes for an impulse to sensed by the decide

9

what are the indications for a temporary pacer

MIS (if they are on beta blockers that slow the heart), emergent situations and elective medical procedures

10

how long does a permeant pacer last?

6 to 12 years

11

what will need to be adjusted on a persons permanent pace maker?

Rate, sensitivity, strength

12

how does the generator function?

pace maker spikes when it doesn't detect a beat for a certain amount of time

13

what is need to be done prior to dc of a someone with pacemaker procedure

cxr to confirm placement
no pnuemothorax
document position of the leads

14

ECG pace maker spikes

look different cause the electrical impulse of the heart does not come from the same place

15

cardiologists pick a pacemaker based on what criteria?

patients dysrhythmia
underlying cardiac function
age

16

Bi ventricular pacing is indicated by?

conduction disturbances
widened QRS greater than 120
ej is less than 35 %
not likely to improve with medications

17

complications of pacemaker implanation

infection at site
dislodged or fractured leads
pacers that dont sense properly
inappropriate delivery of ICD
minimizing patient activity can help prevent complication
patients can reprogram pacers over the phone

18

data for pt record of pace maker

type of pacemaker
type of generator
date and time of insertion
location of pulse generator
stimulation thershold
pacer settings

19

most common complications of pacemaker

bradycardia and decreased cardiac out put

20

indications of ICD

high risk for VT
high risk for VF
survived sudden cardiac death caused by VF
patients who are CHF and 40 days post MI with moderate or severe LV dysfunction
patients can feel the shock

21

how does an ICD work?

monitors heart rhythm identifies and defibrillates in order to get back to sinus rhythm
Includes
anti-tachycardic
cardioversion
defib
bradycardia pacing

22

initial post op mangment of ICD placement

bleeding
hematoma
infection
assess activation status of device, heart rate
report throbbing pain to healthcare provider

23

prior to dc of ICD placement

cxr pneumo and lead placement
no movement

24

cardiologists pick a pacemaker based on what criteria?

patients dysrhythmia
underlying cardiac function
age

25

Bi ventricular pacing is indicated by?

conduction disturbances
widened QRS greater than 120
ej is less than 35 %
not likely to improve with medications

26
