Ventricular arrhythmias originate from the ventricles, often detected by the lack of a discernible P wave. Three main types of ventricle arrhythmias include:
1. Premature Ventricular Contraction (PVC) – A wide and bizarre, premature QRS complex, followed by compensatory pause.
2. Ventricular Tachycardia – Presence of 3 or more PVCs, rate of 150-200 bpm, possible abrupt onset. Possibly due to an ischemic ventricle or electrolyte imbalance.
3. Ventricular Fibrillation – Completely abnormal ventricular rhythm with no discernible QRS complex; ventricles are literally quivering. Requires emergency intervention.
Ventricular Arrhythmias Treatment Treatment is as follows: CHECK FOR PULSE; if no pulse, activate code and begin CPR PVCs: occasional PVCs are common, especially with caffeine or stress. However, check electrolytes if frequent (> 6/minute), as this increases risk of V-tach/V-fib.
V-Tach: Use LAMB to remember treatment: • Procainamide • Amiodarone • Lidocaine • Sotalol
