ectopic atrial tachycardia as the P-waves are upright in lead aVR and negative in lead II.
a Q wave of any size in lll and aVR is normal
loss of R wave progression from V1 to V4 is indications of left ventricular myocardial loss
only lead l reveals true QRS duration
low voltage when QRS is not above 1 big square in any limb lead and 2 bid square in any chest lead
upper limit of T wave is one large square in limb lead and 1.5 square in chest lead...women are 2thirds of these values
in lead l S wave>R wave is a there gold of right axis deviation
right axis deviation is present in hyperkalaemia and pulmonary embolism
a normal p wave with short pR internal.....accessory pathway+delta wave
abnormal p wave with short PR....rhythm from atria elsewhere SA node
p wave is a distortion in T wave..ventricular rhythm
