Narrow complex =
QRS <0.12s
Narrow complex tachycardia is just
a fast rhythm (>100) with a narrow QRS- sinus tachy- sinus arrhythmia- junctional tachy- Afib- A flutter- Atrial tachycardia
supraventricular tachycardia
supra = abovetachy = HR > 100umbrella term used to describe tachyarrhythmias that originate above the ventriclesusually used when there are 3 or more ectopic beats in a row at a rate greater than 100
SVT
HR > 100can't discern P waves from T waves from F wavesnarrow QRS <0.12s
Paroxysmal SVT (PSVT)
means it comes and goes, starts and stops abruptlyoften initiated by a premature beat
