Supraventriculaire ritmestoornissen komen uit de atria. Voorbeelden zijn:

• Sinustachycardie
• Atriaal ritme
• Boezemflutter
• Boezemfibrilleren
• Atriale Tachycardie
• Atrio-ventricular Reentry Tachycardie AVRT

Supraventriculaire ectopische slagen kunnen leiden tot:

• Boezemextrasystole
• Wandering pacemaker

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
