BACKGROUND A number of studies have shown that non-critical medical devices can be contaminated with pathogens, including those resistant to antibiotics and thus become a potential vector for transmission. Electrocardiography (ECG) lead wire are non-critical medical device which are always attached on patient skin during their stay in intensive care unit (ICU). In view of the patient's critical...
BACKGROUND Atrial fibrillation (AF) is a frequent cause of stroke, but detecting paroxysmal AF (pAF) poses a challenge. We investigated whether continuous bedside ECG monitoring in a stroke unit detects pAF more sensitively than 24-hour Holter ECG, and tested whether examining RR interval dynamics on short-term ECG recordings using an automated screening algorithm (ASA) for pAF detection is a u...
In the application of telemedicine, ECG signal is transmitted to the Doctor end without any patient details. As a result, confusion is arisen between signal and patient’s identity. To avoid this confusion, ECG signals need to be combined with patient confidential information when sent. A typical ECG monitoring device generates massive volumes of digital data. Huge amount of bandwidth is require...
سیگنالهای الکترومایوگرام (EMG) که از عضلات تنه، مانند عضله راست شکمی و عضله مایل خارجی، برداشت میشوند؛ غالباً تحت تأثیر فعالیت الکتریکی عضله قلب (ECG) قرار میگیرند. در این مقاله روشی جدید برای حذف تداخل ECG از EMG بر اساس تجزیه سیگنال به حالت تجربی معرفی شده است. روش پیشنهادی با روش فیلتر بالاگذرباترورث مقایسه شد و نتایج حاصل از تحلیل سیگنالهای تداخل یافته...
An attempt was made to derive a useful noninvasive index to evalute a change in myocardial contractile state using transcutaneous Doppler flow-velocity curve from the carotid artery. In 5 mongrel dogs and in 43 patients with various heart disease, Doppler flow velocity curves were obtained from the ascending aorta intravascularly using a Doppler catheter and/or from carotid artery transcutaneou...
BACKGROUND Electrocardiogram (ECG) is commonly used in diagnosis of heart diseases, including many life-threatening disorders. We aimed to assess skills in ECG interpretation among Polish medical students and to analyze the determinants of these skills. MATERIAL AND METHODS Undergraduates from all Polish medical schools were asked to complete a web-based survey containing 18 ECG strips. Quest...
Background & Objective: Patients with ischemic heart disease classified to two major groups: patients with stable angina and patients with Acute Coronary Syndrome (ACS). Previous studies showed that posterior segment of left ventricle is a silent segment on ECG, and routine 12 leads electrocardiogram (ECG) is not sensitive for evaluation of posterior infarction. This study designed for evaluati...
