62. The utility of the triage electrocardiogram for the detection of ST-segment elevation myocardial infarction. (PubMed)

The utility of the triage electrocardiogram for the detection of ST-segment elevation myocardial infarction. Current AHA/ACC guidelines on the management of ST-elevation myocardial infarction (STEMI) suggest that an ECG is indicated within 10minutes of arrival for patients arriving to the Emergency Department (ED) with symptoms concerning for STEMI. In response, there has been a creep towards performing ECGs more frequently in triage. The objectives of this study were to quantify the number

64. Normal Values of Corrected Heart-Rate Variability in 10-Second Electrocardiograms for All Ages (PubMed)

Normal Values of Corrected Heart-Rate Variability in 10-Second Electrocardiograms for All Ages Purpose: Heart-rate variability (HRV) measured on standard 10-s electrocardiograms (ECGs) has been associated with increased risk of cardiac and all-cause mortality, but age- and sex-dependent normal values have not been established. Since heart rate strongly affects HRV, its effect should be taken into account. We determined a comprehensive set of normal values of heart-rate corrected HRV derived

65. Fulminant Type 1 Diabetes Mellitus Complicated with a Life-threatening Electrolyte Abnormality and Abnormal Electrocardiogram Findings (PubMed)

Fulminant Type 1 Diabetes Mellitus Complicated with a Life-threatening Electrolyte Abnormality and Abnormal Electrocardiogram Findings Fulminant type 1 diabetes mellitus (T1DM) is idiopathic T1DM with the rapid destruction of pancreatic β-cells. We herein report a 48-year-old man who developed fulminant T1DM complicated with a life-threatening electrolyte abnormality and abnormal electrocardiogram findings. He had no remarkable medical history, but one day, he developed general fatigue. His (...) blood glucose level and HbA1c were 806 mg/dL and 6.3%, and his insulin secretion was markedly suppressed. He had ketoacidosis, hyponatremia and hyperkalemia. Furthermore, a life-threatening abnormality was noted on electrocardiogram. After fluid infusion and insulin therapy, the abnormality disappeared. In conclusion, we should bear in mind the possibility of fulminant T1DM in patients complaining of general malaise.

66. Electrocardiogram Changes of Donepezil Administration in Elderly Patients with Ischemic Heart Disease (PubMed)

Electrocardiogram Changes of Donepezil Administration in Elderly Patients with Ischemic Heart Disease Donepezil, a widely used cholinesterase inhibitor for treating Alzheimer's disease, has been reported to induce bradyarrhythmias and torsade de pointes. In this study, we aimed at determining electrocardiogram changes of donepezil administration in elderly patients with ischemic heart disease, who tend to suffer from cognitive disorders.Sixty patients with ischemic heart disease and mild (...) cognitive impairment were treated with donepezil (5 mg/day) and followed up for at least four weeks. A twenty-four-hour ambulatory electrocardiogram was performed for the analysis of heart rate variability. The ECG parameters including heart rate (HR), PR and RR intervals, QT interval, and QRS duration were recorded at the baseline and after donepezil administration.Donepezil administration resulted in significant reduction in mean HR and the lowest HR and prolongation of PR and RR intervals, whereas

68. Usefulness of simultaneous and sequential monitoring of glucose level and electrocardiogram in monkeys treated with gatifloxacin under conscious and nonrestricted conditions (PubMed)

Usefulness of simultaneous and sequential monitoring of glucose level and electrocardiogram in monkeys treated with gatifloxacin under conscious and nonrestricted conditions Drug-induced cardiac electrophysiological abnormalities accompanied by hypoglycemia or hyperglycemia increase the risk for life-threatening arrhythmia. To assess the drug-induced cardiotoxic potential associated with extraordinary blood glucose (GLU) levels, the effect of gatifloxacin (GFLX) which was frequently associated (...) with GLU abnormality and QT/QTc prolongations in the clinic on blood GLU and electrocardiogram (ECG) parameters was investigated in cynomolgus monkeys (n=4) given GFLX orally in an ascending dose regimen (10, 30, 60 and 100 mg/kg). Simultaneous and sequential GLU and ECG monitoring with a continuous GLU monitoring system and Holter ECG, respectively, were conducted for 24 h under free-moving conditions. Consequently, GFLX at 30 and 60 mg/kg dose-dependently induced a transient decrease in GLU without

A Case of Type I and II Brugada Phenocopy Unmasked in a Patient with Normal Baseline Electrocardiogram (ECG) BACKGROUND Brugada pattern on electrocardiogram (ECG) is seen when there are at least 2 mm J-point elevation and 1 mm ST-segment elevation in two or more of the right precordial leads, with right bundle-branch block (RBBB)-like morphology. Elevation of a coved-type shape in leads V1 and V2 is consistent with type I Brugada pattern, whereas elevation of a saddle-back configuration

72. Electrocardiogram Delineation in a Wistar Rat Experimental Model (PubMed)

Electrocardiogram Delineation in a Wistar Rat Experimental Model The extensive use of electrocardiogram (ECG) recordings during experimental protocols using small rodents requires an automatic delineation technique in the ECG with high performance. It has been shown that the wavelet transform (WT) based ECG delineator is a suitable tool to delineate electrocardiographic waveforms. The aim of this work is to implement and evaluate the ECG waves delineation in Wistar rats applying WT. We also (...) describe the ECG signal of the Wistar rats giving the characteristics of its spectrum among other useful information.We evaluated a delineator based on WT in a Wistar rat electrocardiograms database which was annotated manually by experienced observers.The delineation showed an "overall performance" such as sensitivity and a positive predictive value of 99.2% and 83.9% for P-wave, 100% and 99.9% for QRS complex, and 100% and 99.8% for T-wave, respectively. We also compared temporal analysis based ECG

Nontraditional Electrocardiogram and Algorithms for Inconspicuous In-Home Monitoring: Comparative Study Wearable and connected in-home medical devices are typically utilized in uncontrolled environments and often measure physiologic signals at suboptimal locations. Motion artifacts and reduced signal-to-noise ratio, compared with clinical grade equipment, results in a highly variable signal quality that can change significantly from moment to moment. The use of signal quality classification (...) electrocardiogram (ECG) integrated into a toilet seat; a device plagued by many of the same challenges as wearable technologies and other Internet of Things-based medical devices.The present algorithms were validated using a study of 25 normative subjects and 29 heart failure (HF) subjects. Measurements captured from a toilet seat-based buttocks electrocardiogram were compared with a simultaneously captured 12-lead clinical grade ECG.

75. Novel Method to Efficiently Create an mHealth App: Implementation of a Real-Time Electrocardiogram R Peak Detector (PubMed)

Novel Method to Efficiently Create an mHealth App: Implementation of a Real-Time Electrocardiogram R Peak Detector In parallel to the introduction of mobile communication devices with high computational power and internet connectivity, high-quality and low-cost health sensors have also become available. However, although the technology does exist, no clinical mobile system has been developed to monitor the R peaks from electrocardiogram recordings in real time with low false positive and low (...) false negative detection. Implementation of a robust electrocardiogram R peak detector for various arrhythmogenic events has been hampered by the lack of an efficient design that will conserve battery power without reducing algorithm complexity or ease of implementation.Our goals in this paper are (1) to evaluate the suitability of the MATLAB Mobile platform for mHealth apps and whether it can run on any phone system, and (2) to embed in the MATLAB Mobile platform a real-time electrocardiogram R

When a Pseudo-Infarct Electrocardiogram (ECG) Pattern in a Posterior Accessory (Wolff-Parkinson-White) Pathway Masks a True Inferior Infarct BACKGROUND Wolff-Parkinson-White (WPW) pattern is due to a pre-excitation leading to characteristic ECG changes in sinus rhythm as short PR interval, the presence of delta waves, wide QRS complexes, and potentially Q wave-T wave vector discordance (pseudo-infarct pattern). These later changes can mask the underlying ECG depolarizing solely through the His
