CV Conditions Flashcards
agonal rhythm
- irregular heartbeat
- below 20 bpm
- near death
atrial tachycardia
- HR > 100 bpm
- usually associated w increased HR or product of exertion
ventricular tachycardia
- HR > 100 bpm
- usually a regular rhythm
when is ventricular tachycardia most common?
after acute MI
which tachycardia is more pathologic?
ventricular
atrial fibrillation (a-fib)
- most common arrhythmia
- can lead to syncope bc no atrial kick
ventricular fibrillation (v-fib)
chaotic rate and rhythm, will lead to death if not treated
multifocal VT (torsades de pointes)
irregular rhythm and rate > 150 bpm
AV blocks
rhythm disturbance where electrical conduction from atria to ventricles is partially or completely blocked
what amount of ST depression indicates ischemia?
1-2 mm
ST elevation indicates what?
MI
T-wave inversion indicates what?
MI
prominent Q-wave indicates what?
MI
wide QRS indicates what?
bundle branch block
