EKG week 7 & 8
EKG week 7 & 8 Hypertrophy & Arrhythmias
| Question | Answer |
|---|---|
| left atrial hypertrophy | Myocardium thickens Shows on V1 biphasic pwave |
| biphasic | pwave has both positive and negative |
| right atrial hypertrophy | atrium is thickened lead 2 peaked pwave |
| biatrial hypertrophy | when both happen biphasic pwave V1 and peaked pwave lead 2 |
| premature atrial contractions | shorter R-R - longer R-R a beat comes premature with a rhythm* |
| nonconducted premature atrial contractions | pwave without a QRS long R-R is call: "Cause for the Pause" with rhythm* |
| paroxysmal atrial tachycardia | PAT=SVT supraventrical tachycardia starts and stops quickly rate 150bpm won't see pwave they are there but hidden |
| atrial flutter | SA not firing, any rate, NO PWAVE flutter waves are saw toothed |
| atrial fibrillation | irregularly irregular NO PWAVE any rate, QRS normal |
| wandering atrial pacemaker | pwaves are all different shapes and sizes. rhythm regular or slightly irregular |
| left bundle branch block | only on V1 the QRS is wide .12 or greater & 99% NEGATIVE V2 can not know right or left BBB |
| right bundle branch block | on V1 QRS is wide .12 or greater and POSITIVE has rwaves |
| premature ventricular contraction | no pwave, wide QRS, will have normal sinus rhythm 1 or 2 beats will have short R-R - long R-R |
| bigeminal | every other beat is a PVC |
| trigeminal | every third beat is a PVC |
| couplet | 2 PVC in a row (paired) |
| triplet | 3 PVC in a row |
| 4 PVC or more | a run of ventricular tachycardia |
| unifocal | all look a like |
| multifocal | all look different |
| ventricular tachycardia | Vtach 250bpm QRS.12-.22 pic pg199 |
| ventricular fibrillation | Vfib chaotic rhythm NO QRS complex pic pg 202 |
| asystole | flatline |
| premature junctional contraction | short R-R - long R-R delay at AVnode pwave can be negative, No pwave or pwave after QRS pic pg144 |
| juctional rhythm | regular rhythm, rate 40-60bpm, pwave may or may not, PR interval short .08 QRS normal .04-.11 |
| accelerated juntional | regular rhythm, rate 60-100bpm, pawave may or may not, PR interval short, QRS normal .04-.11 |
| junctional tachycardia | regular rhythm, rate 100bpm or above, pawave may or may not, PR interval short, QRS normal .04-.11 |
