Overzicht van supraventriculaire tachycardiën
regularity atrial frequency ventricular frequency origin (SVT/VT) p-wave effect of adenosine
Narrow complex (QRS<0.12)
Sinustachycardie regular 100-180 bpm 100-180 bpm sinusnode (SVT) precedes every QRS complex gradual slowing
Boezemfibrilleren grossly irregular 400-600 bpm 75-175 bpm atria (SVT) absent slows down rate; irregularity remains
Boezemflutter regular (sometimes alternating block) 250-350 bpm 75-150 bpm (3:1 or 2:1 block is most common) atria (SVT) negative sawtooth in lead II temporary reduced conduction (e.g. 4:1)
AVNRT regular 180-250 bpm 180-250 bpm AV-node (SVT) in QRS complex (R') stops
Atriale Tachycardie regular 120-250 bpm 75-200 bpm atria precedes QRS, p wave differs from sinus-p temporary AV-block
Atrio-Ventricular Reentry Tachycardie (AVRT)- orthodroom regular 150-250 bpm 150-250 bpm circle: av-node - ventricles - bypass - atria RP < PR stops
AV junctional tachycardie regular 60-100 bpm 70-130 bpm AV node RP < PR reduces rate
Wide complex (QRS>0.12)
Supraventriculaire tachycardie met block (ir)regular depending on SVT 150-250 bpm 75-200 bpm atria (SVT) absent temporary increased AV-block (eg 4:1)
Atrio-ventricular Reentry Tachycardie (AVRT) - antidroom regular 150-250 bpm 150-250 bpm circular: bypass - atria - av-node - ventricles RP < PR stops
