Addendum: ECG changes in left ventrocular hypertrophy

ECG changes in left ventricular hypertrophy
If there is left ventricular hypertrophy then this will result in :
~a tall R wave (greater than 25mm in V5 or V6), or R plus S greater than 35 mm (1)
~a deep S in V1 or V2
~if there is significant left ventricular 'strain' then there are also inverted T waves in V5 and V6 and possible ST depression
~left axis deviation may also be present
~QRS may be slightly prolonged
