ABSTRACT: By means of a satellite transmitter nearby the subject an electrocardiogram can be obtained by telemetry in a hospital electrocardiographic (ECG) laboratory from an area of approximately 20 miles in diameter within the city of London, Ontario. The technique employed in this preliminary trial produced excellent tracings, quite comparable to tracings obtained using the same leads with direct recording. Ninety-four trials were performed on 63 subjects, 37 of whom were patients with a suspected or known myocardial abnormality. A normal group of 26 healthy subjects, 16 of whom were strenuously exercised on a bicycle ergometer to the point of physical exhaustion, were also studied. Monitoring patients during ordinary daily activities has proved extremely useful in the detection and diagnosis of cardiac arrhythmias, intermittent conduction disturbances, latent coronary artery disease, and asymptomatic heart disease.Canadian Medical Association journal 01/1966; 93(23):1187-99. · 7.27 Impact Factor -
Article: The use and effectiveness of electrocardiographic telemetry monitoring in a community hospital general care setting.

ABSTRACT: The purpose of this study was to determine if rates of telemetry events differ between patients whose monitoring is appropriately "indicated" versus "not indicated" by systematically applying rigorous criteria for appropriateness of electrocardiogram (ECG) telemetry usage. We performed a retrospective cohort study on 1097 telemetry admissions between January 1, 2000 and March 31, 2000. A convenience sample of 218 patients generated 236 telemetry admissions. One-hundred-sixty-two arrhythmic events were detected during 400 "indicated" telemetry days. Nine arrhythmic events were detected during 345 "not indicated" telemetry days. The relative rate for arrhythmic events was significantly different, at P < 0.0001, with the incidence rate ratio of 15 indicating a very large effect size. Consequently, current use of ECG telemetry may not be optimal, and a prospective analysis of the application of rigorous indications for ECG telemetry needs to be undertaken. IMPLICATIONS: The application of standard criteria to electrocardiogram telemetry admissions found that the majority of abnormal heart rhythms were found when patients met appropriate criteria.Anesthesia & Analgesia 11/2003; 97(5):1483-7. · 3.29 Impact Factor -
Article: Prediction of the need for intensive care in patients who come to the emergency departments with acute chest pain.

ABSTRACT: Patients who come to the emergency department with chest pain are a heterogeneous group. Some have ischemic heart disease that may lead to serious complications, whereas others have minor disorders. We performed a study to identify clinical factors that predict which patients will have complications requiring intensive care. We first studied 10,682 patients with acute chest pain at seven hospitals between 1984 and 1986 (derivation set) to identify potential clinical predictors of the development of major complications. We then validated these predictors in a separate set of 4676 patients at one hospital between 1990 and 1994 (validation set). In the derivation set of patients, we identified the following set of clinical features, which, if present in the emergency department, were associated with an increased risk of complications: ST-segment elevation or Q waves on the electrocardiogram thought to indicate acute myocardial infarction, other electrocardiographic changes indicating myocardial ischemia, low systolic blood pressure, pulmonary rales above the bases, or an exacerbation of known ischemic heart disease. On the basis of these criteria, the patients in the validation set were stratified into four groups, with the risk of major complications in the first 12 hours ranging from 0.15 to 8 percent. After 12 hours, the probability of a major complication could be updated on the basis of whether the patient had already had a complication of major severity, a complication of intermediate severity, or a myocardial infarction (independent relative risks, 18.9, 7.7 and 4.0, respectively, as compared with patients without prior complications or myocardial infarction). The risk of major complications in patients with acute chest pain can be estimated on the basis of the clinical presentation and new clinical observations made during the hospital course. These estimates of risk help in making rational decisions about the appropriate level of medical care for patients with acute chest pain.New England Journal of Medicine 07/1996; 334(23):1498-504. · 53.30 Impact Factor
