Question: Abstract: The risk of developing spontaneous ventricular tachycardia (VT) and/or sudden death ("arrhythmic events") was prospectively assessed in 165 patients who survived acute myocardial infarction. Signal-averaged electrocardiograms (ECGs) were performed before hospital discharge and then serially at regular intervals over the following year. In addition, 24 hr Holter monitoring was performed and left ventricular ejection fraction was determined. Sixty-five patients (group 1) had abnormal signal-averaged ECGs (voltage in the last 40 msec of the filtered QRS less than 20 microV or filtered QRS duration greater than 120 msec), 92 had normal signal-averaged ECGs (group 2), and eight had bundle branch block (excluded from analysis). In group 1, spontaneous normalization of the voltage in the last 40 msec of the QRS complex occurred in 30% of patients after 12 months, although total filtered QRS duration did not change overall. During follow-up of up to 20 months (median 11), seven patients died suddenly and six presented again with spontaneous, symptomatic VT. Eleven of 65 (17%) group 1 patients had an arrhythmic event compared with one of 92 patients (1%) in group 2 (p less than .001). The sensitivity of the signal-averaged ECG as a predictor of arrhythmic events was 92% with a specificity of 62%. Patients with subsequent arrhythmic events had considerably lower voltage in the last 40 msec of the QRS (11.0 +/- 8.3 vs 32.0 +/- 21.9 microV; p less than .001) than those without such events, and longer filtered QRS complexes (121 +/- 14 vs 105 +/- 12 msec; p less than .001). Multivariate logistic regression determined that the signal-averaged ECG provided independent prognostic information from the presence of complex ventricular ectopy and the degree of left ventricular dysfunction assessed at the time of hospital discharge. Signal-averaged ECGs provide important prognostic information in identifying patients at risk of arrhythmic events after myocardial infarction. Dynamic changes in the terminal QRS voltage are observed during the first year after myocardial infarction.
Which is the apt title for the abstract? option1: Late potentials detected after myocardial infarction: natural history and prognostic significance. option2: Sulindac-associated small bowel lesion.

Answer: Late potentials detected after myocardial infarction: natural history and prognostic significance.

Question: Abstract: To study patient preferences on physician attire and etiquette, we interviewed 200 patients on the general medical services of teaching hospitals in Boston and San Francisco. Of these 200 patients, 65% believed physicians should wear a white coat, 27% believed physicians should not wear tennis shoes, 52% believed physicians should not wear blue jeans, 37% believed male physicians should wear neckties, and 34% believed female physicians should wear dresses or skirts. Forty percent of patients wanted physicians to address them by first name, but only 10% of patients wanted to address their physicians by first name. A concurrent mailed survey of 74 medical house staff members at the two hospitals revealed wide variability in physicians' attire and in how patients were addressed at each institution. Thus, many house officers had habits that were less formal than a substantial portion of their patients preferred.
Which is the apt title for the abstract? option1: Patient and house officer attitudes on physician attire and etiquette. option2: Current methods of training residents to manage pediatric cardiopulmonary arrests.

Answer: Patient and house officer attitudes on physician attire and etiquette.

Question: Abstract: We studied the importance of a history of appendectomy for appendicitis in 279 women with laparoscopically or surgically diagnosed tubal infertility and a control group of 957 fertile women. After controlling for the effects of age, use of an intrauterine device for contraception, a history of pelvic inflammatory disease, and other potential confounding variables, we found that no excess risk of tubal infertility was associated with a simple appendectomy without rupture. However, when the operation was reportedly for a ruptured appendix, the relative risk of tubal infertility was 4.8 (95 percent confidence interval, 1.5 to 14.9) for women who had never been pregnant and 3.2 (95 percent confidence interval, 1.1 to 9.6) for women with one or more previous pregnancies. We conclude that the early diagnosis and treatment of suspected appendicitis in girls and women of reproductive age may reduce the incidence of tubal infertility resulting from the sequelae of a ruptured appendix.
