|
What is the atrial kick?
What causes a lack of an atrial kick? |
Motion that kicks out the additional 1/3.
Atrial flutter or atrial fibrillation |
|
|
|
What is an ectopic beat?
|
Any beat outside the normal rhythm
|
|
|
|
What is a PAC?
Standards of PAC seen in ECG strip? |
A beat that happens before the next expected beat
Must be: -premature -looks different than norm rhythm -pause before the next beat |
|
|
|
What is the clear difference between PACs and PVCs despite their locations?
|
PVCs do not need to reset themselves and thus will have no pause
|
|
|
|
What is used diagnostically and may convert the rhythm of PSVT?
|
Adenosine
|
|
|
|
What are the characteristics of Atrial Fibrillation?
|
No identifiable P waves w/ irregular R-R intervals
Cont-<100, Uncont->100 |
|
|
|
Adenosine, used to treat PSVT, needs to be given how and what signs and symptoms are expected following administeration?
|
Slam it in, follow with flush
Brief period of asystole expected Nausea and vomiting will probably occur |
|
|
|
What is the standard atrial rate in Atrial Flutter?
|
250-350beats/min
be suspicious if atrial rate doubles ventricular rate |
|
|
|
What is one method used to treat new atrial fibrillation?
|
Cardioversion
|
|
|
|
What is unique about Multifocal Atrial Tachycardia?
|
P waves appear different due to rhythms rom atria arising from different areas
|
|
|
|
In ALL heart blocks, P-P is what? and R-R is what?
|
P-P=regular
R-R=regular or irregular Problem is that the impulse from the SA node is not transmitting. Problem is usually the AV node |
|
|
|
What is the characteristic of Second Degree AV Block Type I?
|
Progressive lengthening of the PR interval until you drop a QRS complex
|
|
|
|
What is the characteristic of Second Degree AV Block Type II?
|
More than 1 P wave for each QRS but P's are consistent ALL THE WAY ACROSS THE STRIP
|
|
|
|
When the ventricle response during Second-Degree AV Block Type II is too slow, what happens?
|
Can progress to Third Degree AV Block
|
|
|
|
What is the characteristic of Third-Degree AV Block?
|
There is no relation between the P's and QRS' and the interval is inconsistent
|
|
|
|
What do you do with the pacemaker when the patient's HR is competing with the pacemaker itself?
|
Turn the Pacemaker off
|
|
|
|
What feeds the myocardium during diastole?
|
Coronary Arteries-
Right Coronary, Left Anterior Descedingn, Circumflex |
|
|
|
Name some of the main signs and symptoms of CAD
|
PND, Dyspnea, edema, palpitation, cough, cyanosis
|
|
|
|
What ECG leads correlate to the status of the Right Coronary Artery?
|
2, 3, aVF
|
Inferior Portion of the Heart
|
|
|
What ECG leads correlate to the Left Anterior Descending Artery?
|
aVL, 1, 2, 3
|
|
|
|
What ECG leads correlate to the status of the Circumflex artery?
|
aVL, 1, 4, 5, 6
|
Lateral wall of the heart
|
|
|
Q waves indicate what?
|
Myocardial necrosis
|
|
|
|
Low dose dopamine does what to the heart when given up to 8mcg?
|
increases contractility and renal perfusion
|
|
|
|
What does a dicrotic notch indicate?
|
Increase in aortic pressure
|
|
|
|
What can high SvO2 indicate?
|
sepsis
|
|
|
|
what can low SvO2 indicate?
|
cardiogenic shock
|
|
|
|
What is the DOC for ventricular tachycardia?
|
lidocaine
|
|
|
|
What is the drug therapy for atrial flutter?
|
olol, dipines, THEN class 1 antidysrhythmic agent(quinidine) or amiodarone
|
|
|
|
What is the DOC for second degree AV block, type II?
|
Atropine
|
|
|
|
What is the DOC for SVT?
|
Dipines
|
|
|
|
What is the DOC for sinus bradycardia?
|
atropine
|
|
|
|
What does troponin indicate?
|
myocardial damage
|
|
|
|
What is the most sensitive indicator of an MI?
|
CK-MB- normal level 24-195 but can only be detected 4-8hours after infarct
|
|
|
|
What lab is the quickest indicator of an MI?
|
MB2/MB1 and can be detected as early as an hour following the initial infarct
|
|
|
|
What medications are used to increase the force of myocardial contraction and improve cardiac output?
|
Inotropes!- dopamine(low dose vasodilates, high dose vasoconstricts), dobutamine, epinephrine, norepinephrine, and levophed(doesn't cause tachycardia)
|
|
