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.

The final six leads in the standard 12-lead ECG are designated as the precordial leads and are also unipolar leads.
These are precordial leads view the heart in the horizontal plane.
In our study, ST segment elevation in precordial leads with reciprocal ST depression of >1 mm in inferior leads was seen among 155 (77.
Brugada syndrome is diagnosed in patients with Type 2 or Type 3 ST-segment elevation in [greater than or equal to]1 lead among the right precordial leads V1,V2 positioned in the 2nd, 3rd, or 4th intercostal space when a provocative drug test with intravenous administration of Class I antiarrhythmic drugs induces a Type 1 EKG morphology.

The ECG showed ST-segment elevations were localized at anterior precordial leads in all patients.
The ECG registration on the right hemithorax placement (Figure 4) has shown a right QRS axis deviation at 120 degrees, an important left ventricular hypertrophy with a Sokolow Lyon index of 86 mm (in the precordial leads, there is a special registration with 5 mm standing for 1mV) and inverted T waves from V3 to V6, as well in DIII and aVF.
12) EKG findings include partial or complete right bundle branch block (RBBB) and ST segment elevation in right precordial leads V1 to V3.
However, her ECG showed the sinus rhythm having a heart rate of 55 beats per minute, a PQ interval of 0,16" and tall, peaked T waves in the precordial leads, with a corrected QT interval (QTc) of 510 ms (Figure 1).
A resting electrocardiogram (ECG) revealed sinus tachycardia with a rate of 126 beats/min, normal QRS axis, widespread ST-segment depression in the limb and precordial leads, with ST-segment elevation in the augmented unipolar limb lead (right arm) 0 aVR.
