Diagnosis and quantification of arrhythmias in ambulatory patients using an improved R-R interval plotting system.

An improved technique for identification, diagnosis and quantification of arrhythmias during rest or ambulatory electrocardiographic recording is described. With simultaneous plotting of the R-R interval and the QRS duration and QRS vector measurement of each beat versus time, all periods of arrhythmias or abnormal complexes can be identified and characterized. Analog electrocardiographic samplings are used to confirm the diagnosis of the arrhythmia and to exclude artifact. The availability of a permanent record for the characterization of each QRS complex enables the physician to check the technician's analysis of the recording and to relate all events to the patient's heart rate and clinical symptoms. This technique also provides data for quantification of ventricular arrhythmias.

Neurologic complications of pediatric liver transplantation.

The neurologic complications of 24 children, ages 5 months to 18 years, following orthotopic liver transplantation at the Indiana University hospitals are reported. Biliary atresia (14 patients) was the most common cause for orthotopic liver transplantation. Three children died. Seventeen children (70%) had no neurologic deficit on follow-up 6 months or longer after transplantation. Eleven children (46%), including 4 of 16 patients (25%) who had received OKT3, had neurologic complications. Seven children (29%) had new-onset seizures; 4 of these patients had status epilepticus. Two children had intracranial hemorrhage. Seizures occurred later in children than in adults following orthotopic liver transplantation and were not associated with poor prognosis. Longer term follow-up is indicated to assess subtle, cognitive deficits following liver transplantation in children.

Protocol for lower extremity trauma.

Trauma to the lower extremity has been treated in the past by many specialties and subspecialties of medicine. No specialty, however, should be better qualified or trained in treating lower extremity trauma than the podiatrist. This study reviews some critical principles of acute trauma management and treatment. A simple algorithm is suggested. Three representative case studies are presented, demonstrating the importance and value of an established protocol.

A quality assurance monitor on preparation for outpatient lower endoscopic procedures.

A two-phase quality assurance monitor was performed with a pediatric outpatient population to determine how well the current preparation of Fleet Phospho-Soda, Fleet enemas, and diet modification cleaned the colon. We studied 99 patients in Phase 1, implemented changes, and then studied 99 patients in Phase 2. Phase 2 found increasing age to be significantly related to decreasing cleanliness of the transverse colon, ascending colon, and cecum, and increasing weight was found to be significantly related to decreasing cleanliness of the cecum. Phase 2 also found the second enema to be significant for increasing cleanliness of the rectum.

Physicians' estimates of the probability of myocardial infarction in emergency room patients with chest pain.

To evaluate the ability of emergency room physicians to estimate the probability of myocardial infarction in patients with acute chest pain, the authors gathered historical, physical, and electrocardiographic information from 492 patients at the time of their presentation. The physicians admitted 30% of them to intensive care: 53 of the 61 patients with infarctions (sensitivity = 87%) and 96 of the 431 without infarctions (specificity = 78%). Overall, 36% of those admitted had infarctions. The physicians' numeric estimate of the probability of infarction was a good univariate discriminator of infarction, as demonstrated by Receiver Operator Characteristics analysis, and, as indicated by their actual operating point, they seemed to maximize the accuracy of patient classification rather than sensitivity or specificity. Logistic regression analysis identified the physicians' probability estimate as the strongest multivariate predictor of infarction, considering all other clinical information available.
