Mouse models are extremely important in studying cardiac pathologies and related electrophysiology, but very few mouse ECG analysis programs are readily available. Therefore, a mouse ECG analysis algorithm was developed and validated. Surface ECG (lead II) was acquired during transthoracic echocardiography from C57Bl/6J mice under isoflurane anesthesia. The effect of aging was studied in young ...
BACKGROUND Risk prediction in elderly patients is increasingly relevant due to longer life expectancy. OBJECTIVES This study sought to examine whether electrocardiographic (ECG) changes provide prognostic information incremental to current risk models and to the conventional risk factors. METHODS In all, 6,991 participants from the Copenhagen Heart Study attending an examination at age ≥65 ...
AIMS Electrocardiographic changes, e.g. arrhythmias causing syncope or palpitations, are often transient and therefore difficult to diagnose. Systematic and symptom-activated ECG recordings can increase diagnostic yield in such patients. We evaluated the diagnostic accuracy of a simple, leadless, patient-operated ECG device compared with a standard 12-lead ECG. METHODS AND RESULTS We recorded...
BACKGROUND Methanol is a common commercial compound that can lead to significant morbidity and mortality with high levels of exposure. The purpose of this study was to describe electrocardiographic (ECG) changes associated with methanol intoxication. METHODS A retrospective chart review was conducted with data from Kingston General Hospital collected between 2006 and 2011. Patient data, inclu...
Introduction: It is well known that acute cholecystitis can sometimes mimick coronary ischemia with similar pattern of chest pain and ST segment changes and T-wave inversions in ECG. However, dynamic ECG changes which are highly suggestive of coronary ischemia, in a patient of acute calculous cholecystitis is a rare phenomenon. A normal coronary angiogram established that the peculiar ECG chang...
