Heart axis deviation
Main ECG waves Atrial depolarization (P) axis : it is the general direction in which atrial depolarization conducts Ventricular depolarization (QRS) axis : it is the general direction in which depolarization conducts Ventricular repolarization (T) axis : it is the general direction in which ventricular repolarization conducts Rt : RightLt : Leftmv : Milli voltaVR : Augmented Voltage on Right armaVL : Augmented Voltage on Left armaVF : Augmented Voltage on FootRA : Right AtriumLA : Left AtriumRV : Right VentricleLV : Left VentricleLI : Lead 1LII : Lead 2LIII : Lead 3 Definition Of Mean QRS Axis : The
