A heavy metal shown to cause learning disabilities, behavioral problems, seizures, and even death in children.The Environmental Protection Agency (EPA) estimates that 3 to 4 million children had elevated lead levels in their blood in 1978. The number has now been reduced to several hundred thousand, but elevated lead levels in blood is still the leading environmentally induced illness in children.

Federal law that went into effect in 1996 requires sellers and landlords of properties built before 1978 (when lead-based paint became illegal) to do the following before any contract or lease becomes final:

1. Provide a copy of the EPA booklet, “Protect Your Family from Lead in Your Home.”
2. Disclose any known information concerning lead-based paint or lead-based paint hazards.
3. Provide any records and reports on lead-based paint and/or lead-based paint hazards.
4. Include an attachment to the contract or lease (or language inserted in the lease itself) that includes a lead warning statement and confirms that the seller or landlord has complied with all notification requirements.
5. Provide home buyers a 10-day period to conduct a paint inspection or risk assessment for lead-based paint or lead-based paint hazards.

Using convenience sampling, the first 100 cases admitted between February and November, 2010, with a history of chest pain indicative of unstable angina and with ECG features of typical biphasic T-wave inversion in precordial leads were included.
There were inverted T waves in precordial leads in 12 lead ECG (Figure 1B).
The STsegment should not be assessed exclusively in lead DII, since mild ST- segment changes are not necessarily visible in this lead, requiring the assessment of this segment in the precordial leads (NUNES, 2002), as observed in four animals (11%).
Six additional electrodes are placed at specific locations on the torso overlying the heart as the precordial leads (Wilson, Johnson, & Rosenbaum, 1944; Wilson, Macloed, & Barker, 1931).
Marked repolarization abnormalities were defined as inverted T waves of 2 mm or more in depth in at least three leads, predominantly in the anterior and lateral precordial leads [V.
