1 -Premature Ventricular Contraction ( PVC )
It impulse start ventricle before next normal sinus impulse
Premature = comes early with bizarre shape.
Most of the time accompany sinus rhythm.

wide and bizarre)kemo 2009

Premature Ventricular Contraction ( PVC )Ventricle & a trial rate : depend on rhythm
Ventricle & a trial rhythm : irregular due to early QRS creating PR interval is shorter
QRS shape & duration : duration 0.12 second or more . Bizarre , abnormal shape
P wave shape : visibility p wave depend time of PVC may absent or in front QRS
P-R interval : less than 0,12 second Each P followed by a QRSP: QRS ratio : 0 :1 , 1 :1

2- Ventricular Tachycardia( V-tach.)It three or more PVC in arow A whole strip with PVCs.No P waves.If there is no pulse, it is lethalAlways check the Pulse and BP

Ventricular Tachycardia( V-tach.)
Ventricle & a trial rate : ventricle rate 100 – 200beats /m
QRS shape & duration : duration 0.12 second or more .
P wave shape : very difficult to detect P-R interval : very irregular if see p wave
Each P followed by a QRSP: QRS ratio : more QRS then p wave

3- ventricular FibrillationNo P waves, No QRS, only electrical activity present.
Lethal, always check Pulse and BP
