A systematic approach to pacemaker assessment.

Despite the increasing use of pacemaker therapy, assessment of pacemaker function and electrocardiogram (ECG) interpretation continue to challenge even experienced critical care nurses. Accurate assessment of pacemaker function is essential in the evaluation of patients, especially patients with symptoms that may be related to pacemaker malfunction such as syncope or palpitations. This article will review pacing concepts and pacing system components. A systematic approach to ECG interpretation will be presented that can be used in a variety of clinical settings.

Spinal epidural compression complicating cancer of the cervix: review of seven cases.

Records of women with newly diagnosed cancer of the cervix during a 16-year period were reviewed retrospectively for the development of spinal epidural compression by metastatic tumor (SECMT). Of the 361 cases studied, seven patients (2%) experienced SECMT. Epidural compression often involved the lumbar segment, tended to occur in the nonelderly population, and was relatively protracted in onset following the diagnosis of cervical cancer in cases of metachronous presentations. Although the prognosis was generally poor, the application of therapy may have promoted a better quality of remaining life by relieving pain or restoring the ability to walk.

Preparing for and understanding transesophageal echocardiography.

The transesophageal approach to cardiac echocardiography has expanded the ability of this (almost) noninvasive method of evaluating and diagnosing certain types of cardiovascular pathology. Its use can be expected to increase as echocardiographers become skilled in endoscopy and new applications are discovered.

Treatment in patients with glioblastoma multiforme and poor performance status: is it worthwhile?

It has not been ascertained that treatment of glioblastoma multiforme of the brain (GMB) favorably alters the prognosis in patients with poor pretreatment performance status (PPS). We report on 52 patients with GMB and PPS. The mean survival of 43 treated persons was 19 +/- 12 months (95% confidence interval) and of nine untreated individuals, 2 +/- 1 months (p > 0.50); the corresponding survival rates at 1 year were 39 +/- 16% and 0% (p > 0.05) and at 2 years, 15 +/- 12% and 0% (p > 0.40). We recommend active treatment of patients with GMB even when they present with poor functional status.
