Supraventricular tachycardias
| example (lead II) | regularity | atrial frequency | ventricular frequency | origin (SVT/VT) | p-wave | effect of adenosine | |
|---|---|---|---|---|---|---|---|
| Narrow complex (QRS<0.12) | |||||||
| Sinustachycardia | 
|
regular | 100-180 bpm | 100-180 bpm | sinusnode (SVT) | precedes every QRS complex | gradual slowing |
| Atrial Fibrillation | 
|
grossly irregular | 400-600 bpm | 75-175 bpm | atria (SVT) | absent | slows down rate; irregularity remains |
| Atrial Flutter | 
|
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 |
| Atrial Tachycardia | 
|
regular | 120-250 bpm | 75-200 bpm | atria | precedes QRS, p wave differs from sinus-p | temporary AV-block |
| Atrio-Ventricular Reentry Tachycardia (AVRT)- orthodromic | 
|
regular | 150-250 bpm | 150-250 bpm | circle: av-node - ventricles - bypass - atria | RP < PR | stops |
| AV junctional tachycardia | 
|
regular | 60-100 bpm | 70-130 bpm | AV node | RP < PR | reduces rate |
| Wide complex (QRS>0.12) | |||||||
| Supraventricular tachycardia with block | 
|
(ir)regular depending on SVT | 100-250 bpm | 75-200 bpm | atria (SVT) | absent | temporary increased AV-block (eg 4:1) |
| Atrio-ventricular Reentry Tachycardia (AVRT) - antidrome | regular | 150-250 bpm | 150-250 bpm | circular: bypass - atria - av-node - ventricles | RP < PR | stops | |
