Narrow Complex Tachycardias

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
