Term
|
Definition
primary: prolonged PR secondary 1: progressively prolonging PR followed by dropped beat secondary 2: some p waves dont make QRS (dropped beats occassionally) tertiary: no association twix P waves and QRS |
|
|
Term
|
Definition
irreg ryhtm (usually with respirations and normal). all the P waves look the same |
|
|
Term
|
Definition
irreg rythm with change in P wave shape as the location changes. |

Term
rate in wandering pacemaker |
|
Definition
|
|
Term
what looks like a wandering pacemaker but with a higher rate |
|
Definition
multifocal atrial trachycardia. |
|
|
Term
speed of the different escape ryhtms |
|
Definition
atrial: 60-80 junctional: 40-60 ventricular: 20-40 (will have a wider QRS) |
|
|
Term
|
Definition
when the SA node doesnt fire and a new focus gives a rescue beat before SA resumes |
|
|
Term
What is the qrs is wide in an escape beat? |
|
Definition
the beat is coming from the ventricle |
|
|
Term
what are the premature beats? |
|
Definition
1. PAC 2. premature junctional beat 3. PVC |
|
|
Term
|
Definition
abnormal p wave shape compared to the other P waves
may or may not have a QRS |
|
|
Term
|
Definition
abnormal QRS interval weird, wide QRS bigeminy, trigeminy, quadrigeminy |
|
|
Term
paroxsysmal atrial tachycardia |
|
Definition
irritable atrial focus at 150-250 bpm |
|

look at the QRS in V1 or V2 has an R and R' |
|
|
Term
|
Definition
look at QRS in V5 or V6 has R and R' |

Term
What leads do you look at to determine axis? |
|
Definition
|
|
Term
When can you NOT comment on atrial hypertrophy |
|
Definition
if there is a flut or a fib |
|
|
Term
What lead do we look at for atrial hypertrophy |
|
Definition
|
|
Term
How do we determine atrial hypertrophy? |
|
Definition
R: large diphasic P wave with tall initial component in V1
L: large diphasic P wave with tall terminal component in V1 |
|
|
Term
What does RVH look like on EKG |
|
Definition
1. R>S in V1 2. The R gets smaller as you move from V1 to V6 3. S wave persists in V5 and V6 4. R axis deviation |
|
|
Term
What does LVH look like on EKG |
|
Definition
S in V1 + R in V5 > 35mm
also get left axis deviation
also get inverted T waves with rapid upstroke |
|
|
Term
|
Definition
1. Q waves 2. Inverted T 3. ST elevation or depression |
|
|
Term
What does each of the EKG signs of infarct mean? |
|
Definition
q= necrosis inverted t= ischemia ST ele= injury |
|
|
Term
what does it mean to have a "Q wave" |
|
Definition
q wave greater than 1 small square wide |
|
|
Term
features of LAD occlusion |
