ECG Flashcards
1
Q
Ventricular tachycardia
A
Three or more consecutive PVC, rapid
No P-wave, bizarre and wide QRS
2
Q
Ventricular fibrillation
A
Chaotic activity of ventricle, unable to determine rate, indiscernible waves
Erratic activity without QRS
3
Q
AV blocks
A
Abnormal delays or failure to conduct through normal system
3rd° is life-threatening
Pauses just get longer with higher degrees
4
Q
ST depression
A
May indicate ischemia if downsloping
5
Q
ST elevation
A
Shows new MI, injury, or pericarditis
6
Q
Inverted T-wave
A
Indicates ischemia
7
Q
Deep Q waves
A
MI
8
Q
Infarction versus ischemia
A
Infarction is complete blockage, ischemia is partial blockage
9
Q
PVC
A
Premature be arising from ventricle, very large, compensatory pause after
Serious if more than 3–5 consecutive PVC/minute
