100
no atrial or ventricular rhythm
What is asystole
100
how asystole is treated
What is current ACLS guidelines - CPR 2 min, analyze rhythm, epi every 3 to 5 min, can substitute vasopressin for first or second dose epi, 40 units if given
100
Third degree, symptomatic treatment
What is pacing
100
valve between right atria and ventricle
What is tricuspid valve
100
Define preload
What is pressure in the ventricles at the end of diastole
200
rate <60, rhythm irregular, pacemaker AV junction, P wave innverted, may be before QRS, QRS usually normal, amy be greater than 0.12 sec
What is junctional bradycardia
200
A Fib
What is Cardizem or cardioversion
200
rate - normal, rhythm regular or irregular, p wave normal, some may not be followed by QRS, PR constant for conducted beats, QRS may be normal often greater than 0.12 seconds
What is Type 2 Second Degree
200
The coronary arteries are fed during which phase
What is diastole
200
Define afterload
What is resistance against which the heart must pump
300
rate 60 to 100, rhythm irregular, pacemaker SA node, P waves upright and normal, PR normal, QRS normal
What is sinus dysrhythmia
300
Bradydysrhythmias, symptomatic
What is consider atropine, pacing
300
rate - depends on underlying rhythm, rhythm - usually regular, P wave - normal, PR interval - >0.20, QRS - < 0.12
What is first degree block
300
The right coronary artery major branches are (there are 2)
What is posterior descending and marginal artery
300
define chronotropy, inotropy, and dromotropy
What is heart rate, strenght of contraction, and rate of nerve impulse
400
rate 350 or more, can vary, rhythm irregular, P wave not discernible, no pr interval, QRS normal
What is A Fib
400
Acute Coronary Syndrome
What is aspirin, nitro, fentanyl
400
rate - atrial unaffected, ventricular 40 to 60, rhythm - usually regular atrial and ventricular, P Wave - normal, show no relationship to QRS, amy fall within QRS and T wave, PR interval - no relationship between P and R waves, QRS - greater than 0.12
What is third degree block
400
Name the 2 major branches of the left coronary artery are
What is anterior descending and circumflex artery
400
the formula to calculate cardiac output
What is stroke volume X heart rate
500
rate at least 160, rhythm regular, pacemaker in atria, p wave impossible to see, PR usually normal, QRS normal
What is SVT
500
SVT
What is vagal manuvers, adenosine, cardioversion
500
5:4, 4:3, 4:1, 3:1, or 2:1 refers to what in a second degree block
What is ratio of conduction of P waves to QRS complexes
500
What are anastomoses and why are they important
What is communication between 2 or more vessels allowing collateral circulation. It provides an alternative path for blood flow in case of a blockage somewhere in the system
500
Define stroke volume and tell what is the average amount
What is amount of blood ejected in one cardiac contraction, 70 ml is average
