Prevalence of Electrocardiographic Changes and Risk Factors for QTc Prolongation Among Steady State Sickle Cell Disease Patients: Cooperative Study of Sickle Cell Disease

… mplications that predispose patients to sudden cardiac death. This study aims to assess the prevalence of electrocardiogram (ECG) changes and to investigate risk factors associated with increased propensity of QTc prolongation. Methods: This study utilized data from the Cooperative Study of Sickle Cell Disease Cardiac …

Electrocardiogram Abnormality Associated with Methadone Overdose

Utility of Routine 24-Hour Electrocardiographic Holter Monitoring for Detecting Atrial Fibrillation in Patients Admitted with Acute Stroke Syndromes

Objectives: This study aimed to assess the operating characteristics of standard 12-lead electrocardiogram (ECG) and 24-hour Holter studies in detecting atrial tachyarrhythmia in patients with acute stroke syndromes. The study's objective was to determine the potential factors that increased the likelihood of detecting …

Privacy Preserving Federated Learning for Myocardial Infarction Detection from ECG Signals

Myocardial infarction (MI) detection from 12-lead ECG signals is a critical clinical task, yet two key barriers limit the deployment of deep learning models: data privacy regulations that restrict cross-institutional patient data sharing, and severe class imbalance across heterogeneous hospital populations. This paper …

Heart Rate Variability Time Analyses of the Streptozotocin- Diabetic Rat

… ts in the animal heart rate (HR) and heart rate variability (HRV). In particular, 5 minutes of rat (n=13) electrocardiogram (ECG) is acquired hourly for 30 days. At day 10, the animal (n=7) is dosed with STZ and the ECG is analyzed in order to determine the HR and HRV. The HRV is indexed using two time-based analyses, …

IDENTIFICATION OF OBSTRUCTIVE SLEEP APNEA USING ARTIFICIAL NEURAL NETWORKS AND WAVELET PACKET DECOMPOSITION OF THE HRV SIGNAL

… alth disorders, among which is the ability to identify Obstructive Sleep Apnea (OSA) syndrome by means of Electrocardiograph (ECG) signal analysis. In this paper, the standard spectral bands’ powers and statistical interval-based parameters of the Heart Rate Variability (HRV) signal were considered as a form of feature …

Screening of Patients with Snoring and Obstructive Sleep Apnoea using Heart Rate Variability Indices

… ho had undergone polysomnography (PSG) for snoring at Sultan Qaboos University Hospital, Oman. A 24- hour electrocardiogram (ECG) Holter recording was done at home, starting at 10am. Spectral analysis of ECG from sleep Holter and PSG recordings was analysed using fast Fourier transformation (FFT). Results: The ECG RR i …

Cardiac Markers in the Early Diagnosis and Management of Patients with Acute Coronary Syndrome

… e acute coronary syndromes (ACS). The current diagnostic and triage systems based on clinical history and electrocardiograms are insufficient. They may result in some of these patients being misdiagnosed and being admitted to the wrong units or receiving inappropriate care, treatment and investigations. In some patient …

Comparative Study of Ambulatory Blood Pressure Monitoring and Clinic Blood Pressure Measurement in the Risk Assessment and Management of Hypertension

… mber 2009. The following data were gathered: 1) clinic BP measurements; 2) routine blood test results; 3) electrocardiography, echocardiography, and 4) 24-hour ABPM. Results: The mean age of patients was 41.1 ± 8.6 years and 51.9% of them male. Indications for ABPM were: suspected “white coat” hypertension (10.6%), de …

Asymptomatic Permanent Left Bundle Branch Block (LBBB) complicating Diagnostic Left Heart Catheterisation

… vestigations, immediately after the procedure, including routine blood, serial cardiac troponin I, serial electrocardiograms, chest X-ray, and urgent echocardiography were normal and failed to show any possible causation of the LBBB. The results of left heart catheterisation showed two vessel coronary artery disease an …
