ECG Flashcards
What are the inferior leads?
II, III, aVF
2-3 feet
Anterior leads?
V1, V2
1 dick, 2 tits on the anterior
Septal leads
V3, V4
3-4 boogers in the nasal symptom
Anterior-septal leads?
V1-V4
Lateral leads?
I, aVL, V5, V6
1 hand w 5-6 fingers
- Is this shit sinus?
- Look for the P; if there is a P wave, there is a sinus rhythm. Best place to look for lead 2 and V1. If there is, it is a sinus rhythm and it excludes MANY rhythms. “you always want to put the P in the V1
ST segment elevation in V2, V3, V4, V5 and V6 corresponds to _________
Antero(septal) lateral STEMI
what is this?
WPW syndrome (wolf-Parkinson White): slight upslanting delta wave of the QRS wave
Tx: Procainmide
A-fib: no P waves (II, v1); irregularly irregular (in irregular intervals, it is irregular)
A-flutter: no p-waves (II, v1), “sawtooth” pattern
Hypokalemia: LARGEEEEE U wave
How can we tell the difference between hyperkalemia and STEMI?
Hyperkalemia: peaked T-wave “sharp at the top”; someone just grabbed the T-wave and pulled it up.
STEMI: more round/blunted bc S-T is elevated
Prolonged QRS d/t TCA toxicity
Treat: bicarb
Pericarditis:
Diffuse ST-elevation in ALL leads (red)
Diffuse PR- depression (blue)
Multifocal atrial tachycardia: (fast HR d/t atrium, originating from different areas):
3+ different looking P waves associated w/ lung disease (COPD, sarcoidosis)
