42
Patients will typically need _____ after a cardiac ablation procedure
4-7 days of rest
43
Bipolar pacemakers are typically used for...
Ventricular arrythmias
44
Pacemaker/ICD precautions
No lifting arm overhead past 90 degrees for 4 weeks, no shoulder ext or HABD (for ICD or pacemaker) No lifting 10+ pounds PT needs to be aware of what rate sets it off and work 10-20 beats below that (for ICD only) Need to know what kind of pacemaker/ICD it is
45
Carotid endarterectomy is indicated for...
symptomatic patients w/ 50% blockage or asymptomatic patients w/ 60% blockage -This procedure is done due to stroke risk.
46
Carotid Endarectomy precautions
No aggressive side bending or turning of head
47
Abdominal Aortic Anuerysm repair precautions
NO trunk extension, no twisting Dont encourage flexion either patient needs to heal in an upright position -no coughing or huffing early on -encourage bronchial hygene techniques -teach patient to logroll
48
Bronchoscopy risks
Pain limits breathing -> risk of collapsed lung -> teach patient breathing exercises
49
What are the 3 kinds of lung resection
Wedge- piece of lung Lobectomy- whole lobe Pneumonectomy - whole 1 lung
50
Thoracotomy precautions
-no coughing/huffing early on -pt needs to be taught breathing exercises, risk of collapsed lung -shoulder pain is common -no stretching surgical scar areas -dont activate the muscles involved in the surgical area too aggressively
51
From what leads is T wave inversion normal?
Lead 3, Lead V1, and Lead AVR (note: children may have inversion in V1, V2, and V3)
52
P wave inversion on a lead that is not lead 3, AVR, or V1 V2 could potentially mean:
Heart block with a junctional rhythm
53
A ventricular triplet is also called.....
Nonsustained ventricular tachycardia

What medication is often taken to control the side effects of vasodilators?
Beta blockers (to prevent sympathetic compensation)
69
Which of the following is not an antihypertensive: B blocker Aldosterone Antagonist Cardiac Glycoside Ca+ Blocker ARB/ACE inhib Vasodilator DIuretics
Cardiac Glycoside
70
What is Xylocaine and how does it work?
Class 1 Antiarythmic medication, reduces influx of Na+ into cell
71
Beta blockers are class ____ antiarythmcis and calcium channel blockers are class ______
Beta Blockers: 2 Calcium channel blockers: 4
72
How to betablockers help arrhythmias
Block sympathetic excitation
73
Why does hyperkalemia cause arrythmias?
Because it lowers the threshold required for excitation of the myocardium (more potassium= easier to excite and cause an AP)
74
How does digitalis/digoxin help arrhythmias
Slows HR by extending PR interval (depresses AV node conduction)
75
