(288 cards)
In 3rd degree block -CHB, the atrial rate will be ___ from the ventricular rate. Also, the P and the QRS will be ___
- separate;
- dissociated
Preload is
volume
AV node is represented by the ___ on the ECG
PR interval
Percutaneous transluminal coronary angioplasty (PTCA) route
- Go up through femoral artery to aorta
- Inflate and deflate the balloon over and over until wall of the vessel stretches out so it is more patent
- Stent may be placed to keep the vessel open permanently
3rd Letter in Universal Pacemaker Code means
Type of response
What can precipitate angina pain?
- Physical exertion
- Exposure to cold
- Eating a heavy meal
- Stress and emotional factors
- Stimulants
Afterload is
the resistance the left ventricle must overcome to circulate blood
Patients with hyperthyroidism will have a ____ heart rate
much higher
3 types of pacemaker implantation
- External or Transcutaneous
- Internal or Transvenous
- Epicardial
For a patient with ventricular fibrillation, treat with what 3 things?
- CPR
- atropine
- epi
Who’s at risk for Venous PVD?
- Family history
- Patients own history
- > 40 years of age
- Surgery of > 30 mins. duration
- Varicose veins
- Estrogen treatment - BCP or as a cancer treatment
Percutaneous transluminal coronary angioplasty (PTCA) increases myocardial perfusion by
cracking the plaque
If a patient has ventricular tachycardia and has a pulse, what do you do?
Cardiovert
Takotsubo
- “broken heart syndrome”
- release of catecholamines causing a cardio myopathy
Signs of dropped cardiac output
Restlessness, changes in LOC, cool/pale skin
Unstable Angina is ___ pain w/ little or no activity
unpredictable
Pulmonary Embolism
An embolism ( a blood clot) that becomes lodged in the pulmonary artery, obstructing the blood supply to the lungs
Implantable Cardioverter Defibrillators - ICD are used to treat
Life threatening arrhythmias
Low calcium has little effect on the heart but can lead to ____
tetany (intermittent muscle spasms)
Cardioversion is usually an ____ procedure
elective
MI may cause FVE b/c
heart is not adequately pumping, fluid accumulating in lungs (pulmonary edema)
Coronary arteries come off above the
aortic arch and aortic valve
“Capture” in pacemaker terms means
Effective depolarization of the heart by an artificial pacer
If Atheroma ruptures, it can cause a ____
blood clot
