BACKGROUND: Having mobile devices that provide patients with the ability to record and monitor the electrical activity of their heart enhances patient self-care and the early detection of irregular heartbeat (cardiac arrhythmia), yet few such devices exist in Vietnam. Challenges exist for introducing mobile electrocardiography (ECG) monitoring devices in Vietnam, including patient accessibility and affordability. A low-cost mobile ECG monitoring device designed and developed in Vietnam, which allows patients to easily measure their heart's electrical activity and navigate recordings, may be a solution...

Background: In 2015, the neonatal resuscitation guidelines incorporated the use of electrocardiography (ECG) to monitor heart rate of newborns. However, previous studies have indicated that cardiac arrest with pulseless electrical activity rhythm (PEA) may occur in the delivery room, rendering this method problematic. Objective: To evaluate the accuracy of ECG and auscultation to assess heart rate during PEA. Methods: A total of 45 piglets (age 1-3 days, weight 1.7-2.3 kg) were exposed to 30 min normocapnic alveolar hypoxia followed by asphyxia until asystole, achieved by disconnecting the ventilator and clamping the endotracheal tube...

ETHNOPHARMACOLOGICAL RELEVANCE: Realgar (As4 S4 ) has been traditionally incorporated as a chief ingredient in traditional Chinese medicine formulations used to treat inflammation, poisoning, cancer, convulsion, and parasites. However, because of the toxicity of arsenic (As), the safety of realgar has been questioned. AIM OF THE STUDY: Because the toxicity and efficacy of As are closely related to its chemical species, we conducted examinations of As species accumulation and distribution in the rat body after one-time and 30-day realgar administration and then elucidated the probable roles of different As species in the short-term toxicity of realgar...

In pre-hospital emergency, it's essential to immediate recognize cardiac arrest, and use real-time ECG monitoring for patients. We propose a concept of whole-course ECG monitoring and implementation in pre-hospital emergency, and design a portable pre-hospital ECG monitor (Pre-ECG). There are two working modes in Pre-ECG, i.e., rapid detection and continuous monitoring modes. In rapid detection mode, ECG waves and heart rate of patients can be displayed in a few seconds by using metal electrodes, which helps to understand the status of patients' cardiac electrical activity...

Loperamide is an over-the-counter anti-diarrheal medication that is inexpensive, easily accessible, and widely used. It is generally thought to be safe and effective without the potential for abuse. However, recent discovery of its ability to treat opioid withdrawal symptoms at high doses has led to not only its abuse, but also the need to recognize its cardiotoxicity due to the ability to prolong the QTc interval. We report a case of a 33 year old female with a history of opioid dependence who presented to the emergency department with acute onset shortness of breath and generalized weakness who was subsequently found to be in ventricular tachycardia...

A hand-held electrocardiogram (ECG) monitor with capacitive coupling is designed in this study that can rapidly detect ECG signals through clothing. This new device improves many deficiencies of the traditional ECG monitor, such as infection due to direct skin contacting, inconvenience, and time-consuming. In specificity, the hand-held ECG monitor consists of two parts, a sensor and an embedded terminal. ECG signals are initially detected by a sensing electrode placed on the chest through clothing, then treated by single ended differential amplification, filtering and master amplification, and later processed through A/D conversion and ECG signal transmission by CC2540 module...

In electrocardiography, an electrocardiographic (ECG) artefact is used to indicate a misleading or confusing alteration in data or observation not arising from the heart. Although technological advancements have produced monitors that may provide accurate data and reliable heart rate alarms, interferences of the displayed electrocardiogram such as (but not limited to) electrical interference by outside sources, electrical noise from elsewhere in the body, poor contact and machine malfunction continue to occur...

Electrocardiogram (ECG) false alarms are common in electrically-hostile peri-operative environments. Newer integrated monitoring, with sophisticated hardware and software, has the potential to minimise artefacts. However, monitoring issues continue to occur, with the potential for critical incidents and unnecessary and harmful interventions. We describe the root cause analysis of a series of apparent ECG flatline asystolic events that appeared in the operating room shortly after the introduction of new intra-operative monitoring systems...
