This is a continuing series of objectives to direct resident training in emergency medicine. Electrocardiography may not receive individual attention in many training programs. However, the importance, omnipresence, and medicolegal potential of electrocardiography in the practice of emergency medicine suggests its individual attention. Contents and specific learning objectives are presented to provide guidelines for resident mastery, following the format presented by preceding subjects.

On December 1, 1991, a new federal law designed to increase public use of advance directives takes effect. After that date, health care facilities must provide written information about advance directives to all adult patients. This information must describe (1) the patient's rights to make medical care decisions under state statutes and case law, and (2) how patients can secure these rights within the scope of the provider's policies. ⋯ However, emergency physicians should anticipate that the law will provide not only benefits, but also some burdens. Many institutions will expect emergency department personnel to disseminate and explain the required information, and annotate the medical record. It is the specialty's responsibility to gather empirical data that can guide the use of advance directives in emergency departments.

Case Reports
Emergency department echocardiography in the diagnosis and therapy of cardiac tamponade.
A 44-year-old male presented to the emergency department in shock with jugular venous distension and upper chest cyanosis. Superior vena cava syndrome was ruled out by computed tomography (CT scan). However, a large pericardial effusion was found on CT scan and confirmed by sonography. Pericardial tamponade was diagnosed by emergency physicians and sonography-guided pericardiocentesis was performed with marked improvement in symptomatology.

The cases of two patients with methemoglobin levels approaching 30% are presented. No history of exposure to an oxidant was ever determined for the first case; the second patient had taken amyl nitrate orally along with alcohol as well as a self-injected narcotic and antihistamine. Due to their symptomatology, both patients were treated with methylene blue with good results; however, the patient described in case one had a brief episode of symptoms and pulse oximetry changes, not previously emphasized, consistent with the administration of methylene blue. The pathophysiology of methemoglobinemia, the utility of bedside diagnostic techniques, and the use of pulse oximetry are discussed.
