ECG-VENTRICULAR ARRHYTHMIA (VT)
From NeuroRehab.wiki
SUMMARY
1. Ventricular Tachycardia is defined as 3 consecutive ventricular beats with a rate > 100 beats/min.
2. May be self-limiting or sustained, may be tolerated (conscious VT) or cause life-threatening haemodynamic compromise.
3. ECG shows borad-complex tachycardia (QRS > 120 ms) with no normal looking complexes.
4. VT without a pulse is treated with defibrillation.
5. Conscious VT is treated with anti-arrhythmic drugs (Amiodarone, Lignocaine, Magnesium).
6. Cardioversion may be required. Remember: conscious VT can quickly deteriorate to pulseless VT.
