INTRODUCTION: Ventricular tachycardia (VT) is a life-threatening event. The role of the medical rescue team is to diagnose this disorder on the basis of resuscitation guidelines and general recommendations concerning ECG diagnoses. Patients with ventricular tachycardia, as a result of cerebral hypoxia, may react with aggression. In such situations...

An electrocardiogram (ECG) signal is used widely to detect ventricular tachyarrhythmia (VTA) and to diagnose heart disease. Deep learning models and large ECG data have made the diagnosis of VTA an attractive task to demonstrate the power of artificial intelligence in clinical applications. One of the life-threatening complications of VTA is cardia...
Background:
Although arrhythmias have been reported in patients treated with immune checkpoint inhibitors (ICIs), the association between arrhythmias and ICIs has not been thoroughly evaluated in real-world studies. We aimed to describe the major features of ICI-related arrhythmic events and identify the factors that contributed to death.

Aim of the study
Public access to automated external defibrillators (AEDs) plays a key role in increasing survival outcomes for patients with out-of-hospital cardiac arrest. Based on the concept of maximizing “rescue benefit” of AEDs, we aimed to propose a systematic methodology for optimizing the deployment of AEDs, and develop such strategies for...
Objective:
Heart rate (HR), an essential vital sign that reflects hemodynamic stability, is influenced by myocardial oxygen demand, coronary blood flow, and myocardial performance. HR at the time of the return of spontaneous circulation (ROSC) could be influenced by the β1-adrenergic effect of the epinephrine administered during cardiopulmonary re...
Vasospastic angina is an uncommon cause of cardiac arrest. This report describes a patient who presented with sudden cardiac arrest due to severe coronary vasospasm. Telemetry during the event revealed ventricular arrhythmias and asystole followed by spontaneous self-conversion back to normal sinus rhythm. The patient underwent implantable cardiove...

... [5] Once a patient is suffering cardiac complains, it is essential to avoid any delay between onset of cardiac symptoms, EMS activation, and initiation of early and adequate treatment, as this is clearly associated with improved outcome. [6][7][8] Electrocardiography (ECG) is essential to detect potentially life threatening cardiac arrhythmias and should be used to continuously monitor the heart rhythm. [9,10] Although the ECG is non-invasive and easy to perform, correct interpretation of cardiac pathologies including for example an ST elevation myocardial infarction (STEMI) can be challenging, especially by less to moderately skilled and experienced EMS team members. ...
Electrocardiography (ECG) is essential to detect and diagnose life threatening cardiac conditions and to determine further treatment. Correct interpretation of an ECG can be challenging, especially in the out-of-hospital setting and by less experienced emergency team members.
The aim of this study was to compare the rate of ECG transmission from an out-of-hospital emergency scene to an in-hospital cardiologist on call in EMS-B and EMS-S providers and its impact on direct transportation to a cardiac catheterization laboratory and hospital admission. The study was designed as an observational study. Data from 3 separate emergency medical service teams were collected. Two teams are staffed by paramedics only (EMT-B), while another specialized team is staffed with an emergency physician (EMT-S). 5864 out-of-hospital emergencies were performed during a 12-month period and were analyzed for this study. In 124 out of 5864 (2.1%) out-of-hospital emergencies, an ECG transmission from the out-of-hospital scene to an in-hospital cardiologist on call was performed. Rate of transmission was similar between both teams (EMT-B n=70, 2.2% vs EMT-S n=54, 2.0%, P = .054). After coordinating with the cardiologist on call, 11 patients (15.7%) of the EMT-B (15.7%) and 24 patients (44.4%) of the EMT-S were directly transported from the scene of emergency to a cardiac catheterization laboratory (P < .001). Overall, 80% of patients treated by EMT-S, compared to 52.5% treated by the EMT-B required subsequent hospital admission (P<.05).
Transmission of ECG from the out-of-hospital emergency scene to the in-hospital cardiologist is infrequently performed. The rate of STEMI in transmitted ECG’s by emergency teams staffed with an emergency physician was higher compared to emergency teams staffed with paramedics only.
