AIMS: The detection of non-ischaemic (mainly hypertension, diabetes, and obesity) stage B heart failure (SBHF) may facilitate the recognition of those at risk of progression to overt HF and HF prevention. We sought the relationship of specific electrocardiographic (ECG) markers of SBHF to echocardiographic features of SBHF and their prognostic value for development of HF. The ECG markers were Cornell product (Cornell-P), P-wave terminal force in lead V1 (PTFV1), ST depression in lead V5 V6 (minSTmV5V6), and increased heart rate...

AIMS: ST-segment recovery (STR) is a strong mechanistic correlate of infarct size (IS) and outcome in ST-segment elevation myocardial infarction (STEMI). Characterizing measures of speed, amplitude, and completeness of STR may extend the use of this noninvasive biomarker. METHODS AND RESULTS: Core laboratory continuous 24-h 12-lead Holter ECG monitoring, IS by single-photon emission computed tomography (SPECT), and 30-day mortality of 2 clinical trials of primary percutaneous coronary intervention in STEMI were combined...

Long QT values have been reported in patients with anorexia nervosa of the restricting type (ANr) potentially increasing the risk of fatal arrhythmia, especially if psychotropic drug treatment is required. Nevertheless, the previous studies on this topic are biased by drug exposure, long disease durations, and small sample sizes. This study is aimed at assessing QTc and QTcd values in ANr adolescents with recent onset and drug free, as compared to subjects affected by psychiatric disorders other than ANr. We evaluated QTc and its dispersion (QTcd) in a population of 77 drug-free ANr female adolescents and compared to an equal number of healthy controls (H-CTRL) and pathological controls (P-CTRL, mixed psychiatric disorders)...

BACKGROUND: A slower heart rate can exaggerate J-point elevation in a 12-lead ECG. This study examined the role of Holter monitoring in the diagnosis of early repolarisation pattern (ERP). METHODS: We examined 24-hour Holter recordings of 4000 consecutive patients seen at an outpatient clinic, and found 500 patients (12.5%) with ERP (based on J-point elevation magnitude maximum value≥0.1mV on the Holter recording). The highest magnitude of J-point elevation, R wave amplitude, the ratio between J-point elevation magnitude and R-wave amplitude on the same ECG lead (J/R ratio), QRS interval, and QT/QTc interval were measured on the Holter recording and on a surface 12-lead ECG of the 500 patients with ERP...

BACKGROUND: Patients hospitalized for suspected acute coronary syndrome (ACS) are at risk for transient myocardial ischemia. During the "rule-out" phase, continuous ECG ST-segment monitoring can identify transient myocardial ischemia, even when asymptomatic. However, current ST-segment monitoring software is vastly underutilized due to false positive alarms, with resultant alarm fatigue. Current ST algorithms may contribute to alarm fatigue because; (1) they are not designed with a delay (minutes), rather alarm to brief spikes (i...

Heart failure is a rare cause of wheezing and may develop into a critical condition in children. Few cases report patients with heart failure, secondary to dilated cardiomyopathy, with high fever. A 23-month-old girl visited the emergency department with high fever, cough, first wheezing episode, chest retraction and tachycardia. The chest X-ray revealed consolidation on the left lower lung field; the cardiothoracic ratio was 60%. She was diagnosed with bronchial asthma triggered by pneumonia, which remained unchanged during four visits...

BACKGROUND: Trends in the use of antithrombotic drugs in elderly patients with atrial fibrillation (AF) are largely unknown. We estimated the prevalence of AF in an older population, and examined whether use of anticoagulant and antiplatelet drugs in older AF patients has changed over time. METHODS: Data from the population-based Swedish National study on Aging and Care in Kungsholmen (n=3363, age≥60years, 64.9% women) were used (2001-2004 and 2007-2010). AF cases were identified through 12-lead electrocardiogram, physician examinations, and patient register records (ICD-10 code I48)...

Coated Activated Charcoal Hemoperfusion (CAC-HP) does not reduce the plasma concentration in amitriptyline (AT)-poisoned pigs. The aim of this non-blinded, randomised, controlled animal trial was to determine if CAC-HP reduces the pathological ECG changes caused by AT poisoning. Fourteen female Danish Land Race pigs (mean weight 27.7 kg, range 20-35 kg (CAC-HP) and 24.4 kg, range 18-30 kg (control group, CG), n=7 in each group were included. After randomisation, the pigs were anaesthetised and intravenously poisoned with AT...

OBJECTIVE: ECG ST segment resolution (STR) has been used to assess myocardial perfusion in STEMI patients undergoing PPCI. However, in most of the studies ECGs recorded at different time points after the actual procedure have been used, limiting the options of therapeutic interventions while the patient is still in the catheterisation laboratory. The aim of this study was to investigate the presence and clinical consequences of intra-procedural STR during PPCI. METHODS: We analysed 12 lead ECGs recorded at the onset and the end of the PPCI procedure, measuring STR in the lead with maximum ST elevation on the initial recording...
