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:

| 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 | |
