ABSTRAKSinyal elektrokardiogram (EKG) dapat dianalisis dengan memperhatikan bentuk, durasi, dan irama. Pada penelitian ini, dikembangkan sebuah metode ekstraksi ciri sinyal EKG menggunakan parameter Hjorth statistik. Kedua tersebut diaplikasikan untuk mengekstrak ciri-ciri dari rekaman suara EKG. Terdapat tiga kondisi yang menjadi masukan sistem, normal, atrial fibrillation (AF), congestive hea...

TYPE: Case Report TOPIC: Critical Care INTRODUCTION: Factitious use of insulin, thyroxine, decongestants, laxatives, cocaine, and heroin have been reported to cause hypokalemia. Severe hypokalmeia < 2 mg/L can rhabdomyolysis, arrythmias, seizures warrenting rapid correction. CASE PRESENTATION: A 22-year-old male with recent cocaine presented intractable vomiting, ascending weakness tingling for...

Ein 81-jähriger Patient wird bei plötzlicher Verschlechterung des Allgemeinzustandes auf den Notfall eingewiesen. Er klagt über Müdigkeit, Leistungsminderung, Kurzatmigkeit und Unwohlsein seit dem Vortag.

Myocardial infarction (MI) and massive pulmonary embolism (MPE) are common causes of cardiac arrest. We present two cases with similar clinical presentation and EKG findings but different initial rhythms. Case  1. A 55-year-old African American male (AAM) was brought to the emergency room (ER) with cardiac arrest and pulseless electrical activity (PEA). Twelve-lead electrocardiogram (EKG) was s...

Case. A 64-year-old Caucasian woman was brought to the emergency department with severe dysphagia and left chest pain for last 4 days. Initial evaluation revealed elevated ST segment in precordial leads on EKG with elevated cardiac enzymes. Limited echocardiogram showed infra-apical wall hypokinesia. Cardiac angiography was done subsequently which showed nonflow limiting mild coronary artery di...

Patients may intermittently require antimicrobial therapy with a QTc-prolonging antibiotic, which presents a challenge for prescribers of patients already taking a QTc-prolonging antiarrhythmic. Manufacturers recommend close monitoring for evidence of QTc-prolongation with the concomitant use of QTc-prolonging medications, but the monitoring parameters are not well-defined. Previous studies rec...

Two trials were conducted with a total of 12 beef heifers and steers to determine the effect of 48-hr deprivation of feed or water or both on rectal temperature, respiratory and heart rates, electrocardiograph (EKG) patterns, packed cell volume (PCV) and the concentrations of serum sodium, potassium, calcium and magnesium. The same measurements plus the serum concentration of total acid-soluble...
