A

Twiddlers syndrome

22
Q

What are the benefits of SICDs?

A

No floor needed, Easy to explant, No risk for vascular injury

23
Q

People that receive a biventricular pacemaker usually get what else?

A

ICD

24
Q

What are hiccups suggestive of?

A

Phrenic nerve or diaphragm stimulation

25
Q

What is the most common reason for cardiac implanted lead removal?

A

Device infection

26
Q

What equipment is most important to have on hand when doing a lead wire extraction?

A

pericardiocentesis

27
Q

What kind of battery is a pacemaker?

A

Lithium iodine

28
Q

How long do the batteries last?

A

10-15 years

29
Q

What is normal impedance?

A

300-1500

30
Q

Ohms is greater than 1500

A

Lead wire fracture

31
Q

Change of 700 ohms

A

Lead wire fracture

32
Q

Ohms less than 300

A

33
Q

What is mA set to?

A

2x the diastolic threshold

34
Q

What is the safety margin set at?

A

2x the capture threshold to 1 mA above

35
Q

What kind of pacemaker is prone to cross talk issues?

A

Dual chamber

36
Q

What side is the pacemaker implanted?

A

Patients non dominant side

37
Q

What side is the IV placed on for PPI?

A

On the side on the device placement

38
Q

Placing a magnet over a pacemaker/ ICD will do what?

A

In pacemakers it will change to magnet mode and it will go asynchronous pacing. In ICD it will stop shocking.

39
Q

Which lead is placed first?

A

RV

40
Q

pacemaker signals are evaluated through what?

A

pacing system analyzer (PSA)

7 mV

43
Q

What is the atrial threshold value?

A

1 V

44
Q

What is the ventricular threshold value?

A

3 V

45
Q

How is the pocket sutured?

A

Fascia, Dermis, Epidermis

46
Q

What is done after a device placement?

A

Chest Xray to confirm lead placement, pneumothorax

47
Q

Signs of pacemaker malfunction

A

Syncope, Angina, SOB, Hyperventilation, Hiccoughs

48
Q

For an ICD what should the DFT be set to?

A

10 J higher

49
