What will you learn?
- how to avoid VT/VF induction with your pacing
- when can I expect VT or VF induction
- what to look for and be prepared for
About this scenario
- Do not pace faster than 250 ms because ventricular tachycardia (VT) or ventricular fibrillation (VF) may be induced at higher rates.
- In general extra-stimulus pacing is more likely to induce VF while burst pacing VF.
- For deliberate VT induction drives with multiple extra-stimulus are advisable. Different constellations of short and long intervals should be consider in the induction protocol.
- Look for local signal defragmentation as an early warning prior induction
- Always be prepared for VT/VF induction and emergency measures to insure patient safety.
