Anatomy
Name the av valves and what chambers they separate
Tricuspid, the right atria and ventricle. Bicuspid, the left atria and ventricle
Atrial depolarization is represented by what?
P wave
Normal measurement for PRI and QRS
PRI = greater than .20 QRS less than or equal to .11
Atrial Flutter often has p-waves that resemble what?
saw-tooth
Inherent rate of the AV node
40-60
which chamber of the heart has the thickest wall?
Left ventricle
Ventricular repolarization is represented by what?
T wave
If a QRS measures .12 or greater it is an indicator of what?
IVCD, which is DELAYED VENTRICULAR CONDUCTION
T/F SVT is usually around 150 BPM with No P-waves
True
what does PAC stand for
Premature Atrial Contraction
all cardiac valves have 3 leaflets except which one?
bicuspid
T/F. Junctional p-waves can be biphasic
False
T/F the atrial rate of AFL is 101 to 200
False. AFL is only at 200+
Atrial Fibrillation originates in what?
Multiple ectopic sites in the atria. (it's origin is in the pulmonic vein)
A beat that comes late in the cardiac cycle and come from the junction is a what?
Jeb
Blood flow out of the heart is regulated by what valves?
Semilunar valves
In order to call a sinus p-wave what 4 conditions must be met?
1. Upright 2. Matching 3. In front of the QRS 4. 1:1 ratio with QRS
What is the rate for WAP?
60-100
What is this strip; Sinus beat, sinus beat, sinus beat (all with r to r of 78 bpm) early beat with a wide qrs, NCD followed by a junctional beat with hidden p-wave, sinus beat, early ectopic beat, early ectopic beat, early ectopic beat, NCD, sinus beat.
SR with AP, JEB and ATR
T/F you can have 3 jebs in a row
False. 3 makes a rhythm
From inside to outermost list the 3 layers of the heart.
endocardium, myocardium, epicardium
T/F U waves if present will map out with P-waves
False
The rate of AJR is what?
61-100
an irregular rhythm in repeating cycles of rate increase and decrease is usually a sign of what?
T/F a jeb follow by a pac is an AC
False.
