[[File:E314.jpg|thumb|600px|left|An 84 year old lady with hypertension<br />
There are a number of abnormalities here.<br />
left anterior hemiblock <br />
QRS axis more left than -30 degrees <br />
initial R wave in the inferior leads (II, III and aVF) <br />
absence of any other cause of left axis deviation <br />
left ventricular hypertrophy <br />
In the presence of left anterior hemiblock the diagnostic criteria of LVH are changed. Rosenbaum suggested that an S wave in lead III deeper than 15 mm as predictive of LVH. <br />
long PR interval (also called first degree heart block) <br />
PR interval longer than 0.2 seconds <br />
left atrial hypertrophy <br />
M shaped P wave in lead II <br />
P wave duration > 0.11 seconds <br />
terminal negative component to the P wave in lead V1 <br />
with permision from the site of Dr. Dean Jenkins<br />
