Morphologic criteria to differentiate between SVT vs. VT in a wide complex tachycardia

Arrhythmias (non-normal heart rhythms) can be a challenge to the person who tries to understand them. But with a systematical approach, diagnosis is often less difficult than it seems at the beginning.

First look at the heart rate:

  • >100 bpm = tachycardia
  • <60 bpm = bradycardia
  • are there extra beats? -> Ectopic Beats

Secondly it is important to assess the origin of the arrhythmia:
