These have been added to, creating the 15 rules for 12-lead (and 15- or 18-lead) interpretation. [84] Rule 1: All waves in aVR are negative. Rule 2: The ST segment (J point) starts on the isoelectric line (except in V1 & V2 where it may be elevated by not greater than 1 mm). Rule 3: The PR interval should be 0.12–0.2 seconds long.
Blood lead level (BLL), is a measure of the amount of lead in the blood. [1] [2] Lead is a toxic heavy metal and can cause neurological damage, especially among children, at any detectable level. High lead levels cause decreased vitamin D and haemoglobin synthesis as well as anemia, acute central nervous system disorders, and possibly death. [3]
