Cardiac A&P
Atrial Rhythms
AV Blocks
Ventricular Rhythms
Miscellaneous
100
Systolic BP+2(Diastolic)/3 normal is 65 or greater
What is MAP?
100
ECG wave form that represents atrial depolarization; or atrial contraction
What is P wave?
100
gatekeeper, delays the electrical impulse from SA node to allow atria to contract and complete filling of ventricles.
What is AV node
100
Rhythm characterized by very fast>100 bpm, wide QRS complexes; patient may or may not have a pulse
What is V-tach?
100
diastole
What is the 'fill'?
200
What is referred 'meaty' section of the heart; or muscle of the heart
What is the myocardium?
200
No P waves; irregularly irregular, loss atrial kick
what is atrial fibrillation?
200
Rhythm associated with the atria and ventricles not in relationship anymore; Requires immediate pacing
What is complete heart block?
200
The part of the ECG that if a ventricular stimulus falls on it; can lead to Torsades De Pointes?
What is the T wave?
200
provides remaining 30% of cardiac output into the ventricles.
What is the atrial kick/contraction?
300
This term refers to when the heart is squeezing;
What is systole?
300
HR>150-250, narrow QRS. Decreased cardiac output; treatment requires ACLS medication intervention
What is SVT
300
Is part of a rhythm; wide QRS (>.12), can have right or left (only diagnosed through 12 lead ecg)
What is a Bundle Branch Block?
300
Pacemaker malfunction; pacer spike but no coordinating beat occurs.
Failure to capture
300
Referred to as "Pacemaker of the heart"
What is SA node?
400
P wave, QRS wave, T wave
What is the parts of an ecg waveform?
400
ectopic atrial beat that comes early Part of a rhythm. Usually benign
What is a PAC?
400
Identified by Longer, Longer, Drop (PR interval progressively getting longer; then drop ORS)
What is a 2nd degree type I?
400
type of polymorphic v-tach; associated with prolonged QT syndrome
What is Torsades de Pointes?
400
The expected HR :40-60; it is considered the backup if SA node fails.
What is AV node?
500
After cardiac surgery, pacing wires are surgically placed here; also coronary arteries are found in this layer of the heart.
what is the epicardium
500
biggest risk for patients who have undiagnosed A-fib
What is a stroke or PE.
500
The communication between SA and AV node is getting worse; more QRS beats are getting dropped; pacing may be needed depending on patient condition.
What is Second Degree Type II AV block
500
Chaotic ventricular rhythm; always requires defibrillation & CPR
What is V-fib?
500
PR <.12-.20 QRS <.12 OT/OTc-<.44
What are all the waveform intervals?
