Treatment of asxatic runs of VT (even in acute MI)
|
just correct K and Mg, reperfusion as necessary. But do not need anti-dysrhythmics.
|
|
Initial doses for electrocardioversion of mono- and polymorphic VT
|
mono 100 J
poly 200 J |
|
Types of VT
|
Re-entrant (initiated by a PVC w/ current running through 2 areas w/ different refractory periods)
Triggered (R-on-T leading to alterations in depol/repol pattern) Pacer mediated (ventricular beat conducts retrograde through AV node and triggers, depolarizes atrium which triggers pacer) |
|
Asxatic VT in ischemia
|
1. Make sure K>4, Mg>2
2. Can use Esmolol if good BP (decreases automaticity) 3. Avoid anti-dysrhythmics |
