Q

DDD description

A

Both chambers sensed

Sensed atrial signal causes PM to inhibit the atrial output

If QRS occurs naturally, the PM will inhibit the ventricular output

Q

Pros and cons of rate modulation

For activity based

A

Activity based-

HR response slow with movements that are smooth (biking)

12
Q

Pros and cons of rate modulation

For physiologic based

A

Physiologic- requires longer warmup

Aka slight delay to activity

Q

What shows up in failure to sense

A

Fires in complete disregard to pt’s own rhythm
May compete with heart for control

  1. Under sensing
  2. Oversensing

17
Q

2 simple PT consideration for pacemaker

A

Take BP often

Note change in PM firing rate with activity

18
Q

difficult PT implications for PM

In Tachy dysrhythmia

A

If PM for Tachy dysrhythmia

Note cut off rate

10 beats below cut off rate = max HR for activity

19
Q

difficult PT implications for PM

In Brady dysrhythmia

A

Note if induces symptoms

20
Q

If atrial rate is fixed, what may show up? *****

A

pt. may have blunted HR response to exercise

Indicates longer warm up and cool downs

21
Q

If ventricles are paced what may happen on ECG?

A

ECG may not pick up ischemia

22
Q

PT consideration exercise

A

No lifting x 6 weeks

No over head exercise until Md clears

Avoid contact sport

23
Q

ICD monitors what

A

Heart RHYTHM

24
Q

What dangerous rhythms does ICD detect and amend?

A
  1. V tach
  2. V fib
  3. Previous cardiac arrest
  4. Uncontrolled dysrhythmia with medication
  5. Cardiomyopathy with dysrhythmia
  6. CAD, low LVEF and an episode of V Tach
25
Q

What does ICD do?

A

Prevent sudden cardiac death

26
Q

Battery lifespan of ICD

A

7 years

27
Q

ICD can reset what kind of V yacht problem?

A

Cardio version
Aka V tach

Shocks QRS to reset rhythm

28
Q

When does ICD defibrillate?

A

V fib

When ICD fails to correct the V tach

29
Q

What’s stronger shock from ICD? V fib or V tach?

A

V fib, because ICD fails to correct the V tach

30
Q

Other functions of ICD?

A

Anti tachycardia pacing
Gently shocks to decrease heart pace

Anti bradycardia pacing

31
Q

Mild strong thump of ICD indicates what?

A

Cardio version or defibrillation

32
Q

Define ICD Storm

A

Two or more shocks in 24 hrs

33
Q

When can pt do low to moderate intensity competitive sports?

A

If no dysrhythmia in 6 months

34
Q

How long should pt avoid over head activity?

A

1 month

35
Q

What position of exercises increase RPP via higher HR response?

A

Supine exercises

36
Q

How long no driving after implantation or shock?

A

6 months no driving

37
Q

If at airport how long avoid mania scanner?

A

No more than 30 seconds

38
Q

2 Psychosocial issue with ICD

A

Anxiety

Depression

39
Q

What is associated with Pm increase anxiety?

A

Younger than 50 years old

High number of discharge

Poor understanding of ICD

Poor social support

Poor overall health

40
Q

3

Classification

A

Chambers paced
Chambers sensed
Response to sensed impulse
