A 101 years-old woman was admitted to our Emergency Department (ED) for acute dyspnea which onset nearly two hours before presentation. She had been on hydrochlorothyazyde-amiloride therapy due to mild hypertension. No other relevant features were present in the clinical history. The old lady had never been admitted to the hospital, and she was still living alone. A few days before hospital admission, one of the daughters became ill, so that a caregiver was paid for assisting her 12/24. This new circumstance was reluctantly accepted by the old lady...

OBJECTIVE: Repeated or serial 12-lead electrocardiograms (ECGs) in the prehospital setting may improve management of patients with subtle ST-segment elevation (STE) or with a ST-segment elevation myocardial infarction (STEMI) that evolves over time. However, there is a minimal amount of scientific evidence available to support the clinical utility of this method. Our objective was to evaluate the use of serial 12-lead ECGs to detect STEMI in patients during transport in a Canadian emergency medical services (EMS) jurisdiction...

BACKGROUND: In the general population the leading cause of cardioembolic stroke is atrial fibrillation (AF). A silent AF is also the possible cause of many cryptogenic strokes. P wave dispersion (PWD), a predictor of AF, has been proposed as a marker of silent AF occurrence in these strokes. PWD correlates with high-sensitive C-reactive protein levels reflecting the role of inflammation in promoting a slowed and inhomogeneous atrial conduction. Statins have a multitude of additional effects beyond lipid lowering, in particular anti-inflammatory effects that may influence atrial conduction...

Introduction The History, Electrocardiogram (ECG), Age, Risk Factors, and Troponin (HEART) score is a decision aid designed to risk stratify emergency department (ED) patients with acute chest pain. It has been validated for ED use, but it has yet to be evaluated in a prehospital setting. Hypothesis A prehospital modified HEART score can predict major adverse cardiac events (MACE) among undifferentiated chest pain patients transported to the ED. METHODS: A retrospective cohort study of patients with chest pain transported by two county-based Emergency Medical Service (EMS) agencies to a tertiary care center was conducted...

Overall and abdominal obesity are well-established risk factors for cardiometabolic disease. However, associations of overall and abdominal adiposity with electrocardiographic (ECG) markers of subclinical cardiovascular disease (CVD) have not yet been fully elucidated. Therefore, we investigated these associations in a population without preexisting CVD. We performed cross-sectional analyses in the Netherlands Epidemiology of Obesity Study. Body mass index (BMI), total body fat, and waist circumference were assessed in all participants, and abdominal subcutaneous adipose tissue and visceral adipose tissue (by magnetic resonance imaging) were assessed in a random subgroup...

Aims: Sensitivity to flecainide testing results in suboptimal findings in patients with Brugada syndrome (BrS), leading to safety concerns. Because cardiac syncope effectively predicts outcomes in BrS, we aimed to explore its predictive value in a large cohort of negative and positive responders (NR and PR) to standard flecainide testing. Methods and results : We analysed the data of 251 consecutive patients, 177 NR vs. 74 PR, to flecainide testing, performed according to standard recommendations...

Left anterior fascicular block (LAFB) is a heart disease identifiable from an abnormal electrocardiogram (ECG). It has been reported that LAFB is associated with an increased risk of heart failure. Non-specific intraventricular conduction delay due to the lesions of the conduction bundles and slow cell to cell conduction has also been considered as another cause of heart failure. Since the location and mechanism of conduction delay have notable variability between individual patients, we hypothesized that the impaired conduction in the ventricular myocardium may lead to abnormal ECGs similar to LAFB ECG patterns...

BACKGROUND: Unrecognized myocardial infarction (MI) is a frequent condition with unknown underlying reason. We hypothesized the lack of recognition of MI is related to pathophysiology, specifically differences in underlying small and large vessel disease. METHODS: 6128 participants were examined with retinal photography, ultrasound of the carotid artery and a 12‑lead electrocardiography (ECG). Small vessel disease was defined as narrower retinal arterioles and/or wider retinal venules measured on retinal photographs...

Currently, there is no device capable of detecting acute ischemic stroke (AIS) secondary to emergent large vessel occlusion (ELVO) in the pre-hospital setting. The inability to reliably identify patients that would benefit from primary treatment with endovascular thrombectomy remains an important limitation to optimizing emergency medical services (EMS) triage models and time-to-treatment. Several clinical grading scales that rely solely on clinical examination have been proposed and have demonstrated only moderate predictive ability for ELVO...

Andres Enriquez, Michael Riley, Francis Marchlinski
The electrophysiologic mechanisms responsible for the initiation and maintenance of ventricular tachycardia (VT) include enhanced automaticity, triggered activity and reentry. Differentiating between these three mechanisms can be challenging for the clinician and usually requires an invasive electrophysiology study. Establishing the underlying VT mechanism in a particular patient is helpful to define the optimal therapeutic approach, including the selection of pharmacologic agents or delineation of an ablation strategy...

BACKGROUND: Fragmented QRS (fQRS) on a 12-lead ECG has been linked with adverse outcome. However, the visual scoring of ECGs is prone to inter- and intra-observer variability. METHODS: Five observers, two experienced and three novel, assessed fQRS in 712 digital ECGs, 100 were re-evaluated to assess intra-observer variability. Fleiss and Cohen's Kappa were calculated and compared between subgroups. RESULTS: The inter-observer variability for assessing fQRS in all leads combined was substantial with a Kappa of 0...
