Describe P Pulmonale
Elevated, peaked P wave > 0.2 mV, particularly in II, III and aVF as a sign of right atrial hypertrophy. The PR interval is not considerably prolonged. Frequently associated with signs of right ventricular hypertrophy or vertical range cardiac axis (S I Q III type).
What causes P Pulmonale
volume or pressure overload of the right atrium,
Describe P mitrale
Widening of the P wave > 0.1 s, particularly in I, II and V1 - V 3 as a sign of left atrial hypertrophy. A biphasic P wave with a marked negative deflection in V1 is frequently found and is often associated with signs of left ventricular hypertrophy.
What causes P mitrale
pressure or volume overload of the left atrium,
What causes RVH
Thickening of the right ventricular muscle as a response to chronic volume or pressure overload.
Sokolow index for RVH
R in V 2 + S in V 5 > 1.05 mV.
What causes LVH
Thickening of the left ventricular muscle as a response to chronic pressure or volume overload (hypertension, aortic stenosis).
Sokolow index for LVH
S in V 2 + the R in V 5 > 3.5 mV.
