Yangyi Lin, Danqun Xiong, Fei Wang, Xiangdong Xu
The current guidelines for resting electrocardiograms of diffuse ST segment depression coupled with ST segment elevation in aVR and/or V1 that are otherwise unremarkable indicate multivessel or left main coronary artery obstruction. However, our case meets the above electrocardiogram changes, but involves left circumflex artery occlusion.

OBJECTIVE: To determine the clinical value of correcting the QRS duration for heart rate. BACKGROUND: We recently observed [1] that the QRS duration shortens during spontaneous increases in heart rate. In the current study, we analyzed ECG and pharmacokinetic data of 21 subjects who received quinidine in a recent study [2]. They experienced the expected post-quinidine increase in heart rate, allowing us to determine if quinidine's well-known QRS prolongation might be attenuated due to the concomitant rate increase...

John E Madias
Variation of the amplitude and morphology of V1-V6 leads in serial ECGs, due to variation in the placement of V1-V6 recording electrodes, and the noncompliance in placing the V1-V6 electrodes at the recommended thoracic loci, are 2 problems which have defied solution since the advent of electrocardiography. A proposal is presented herein of a set of 3 recorded leads (conventional limb leads I and II, and a lead recorded via an electrode adjacent to the sternal notch [SNL]), aimed at reconstructing the V1-V6 leads, as a function of the 3 recorded leads, employing patient-specific and general (population) coefficients...

AIMS: Remote monitoring by implantable devices substantially improves management of heart failure (HF) patients by providing diagnostic day-to-day data. The use of thoracic impedance (TI) as a surrogate measure of fluid accumulation is still strongly debated. The multicenter HomeCARE-II study evaluated clinically apparent HF events in the context of remote device diagnostics, focusing on the controversial role of TI. METHODS AND RESULTS: We followed 497 patients (66...

BACKGROUND: An easy-to-operate ECG recorder should be useful for newborn screening for heart conditions, by health care workers - or parents. We developed a one-piece electrode strip and a compact, 12‑lead ECG recorder for newborns. METHOD: We enrolled 2582 newborns in a trial to assess abilities of parents to record a 12‑lead ECG on their infants (2-4 weeks-old). Newborns were randomized to recordings by parents (1290) or our staff (1292 controls). Educational backgrounds of parents varied, including 64% with no more than a high school diploma...

BACKGROUND: P-wave terminal force (PTF) > 4000 ms·μV and deep terminal negativity (DTN) are ECG markers of left atrial abnormality associated with both atrial fibrillation and stroke. When the precordial lead V1 is placed higher than the correct position in the fourth intercostal space, it may cause increased PTF and DTN. Several studies have documented that electrode misplacement, especially high placement, is common. The influence of electrode misplacement on these novel ECG markers has not previously been quantified...

BACKGROUND: P-wave parameters representing atrial conduction heterogeneity are associated with recurrence of atrial fibrillation (AF) after catheter ablation. However, intra- and inter-observer variabilities are unavoidable during manual measurement of P-wave parameters. METHODS: The study included 201 patients with paroxysmal AF who underwent catheter ablation. P-wave duration (PWD) was measured using a computerized automated measurement system with a surface 12-lead electrocardiogram...

BACKGROUND: ST-segment elevation (STE) and an increased Tpeak-Tend interval (Tp-e) have prognostic value for malignant arrhythmia events (MAEs) in patients with ST-segment elevation myocardial infarction (STEMI) and Brugada syndrome. Whether STE could predict MAEs and has an electrophysiological relationship with Tp-e in electrocardiogram (ECG) of vasospastic angina (VA) patients needs to be elucidated. METHODS: Sixty-five patients with VA and 23 patients with VA complicated by MAEs were enrolled...

Cardiomyopathies represent a well-known cause of heart failure and sudden death. Although cardiomyopathies are generally categorized in distinct nosographic entities, characterized by single gene-to-disease causal relationships, recently, oligogenic mutations have also been associated to relevant cardiac clinical features. We report the case of a master athlete carrying trigenic mutations in desmoglein-2 (DSG2), desmocollin-2 (DSC2) and heavy chain myosin 6 (MYH6), which determine a mild hypertrophic phenotype associated both to ventricular tachyarrhythmias and atrio-ventricular block...

INTRODUCTION: We previously reported that LP positive patients after percutaneous coronary intervention (PCI) had higher rate of re-hospitalization in the small-scale study (135 patients). In this study, we evaluated correlation between LP and later cardiac events leading to re-hospitalization more extensively in greater population. METHODS AND RESULTS: A 24-h high-resolution (HR) ambulatory electrocardiogram (ECG) was performed in 421 patients that received PCI for the treatment of acute coronary syndrome (ACS) within 30 days...

AIMS: Migraine is a chronic neurovascular disorder characterized by intermittent episodes of severe headache. Abnormalities in the autonomic nervous system (sympathetic and parasympathetic nervous systems) have been detected during migraine-free periods in patients with migraine. In these patients, disrupted autonomic innervations of the heart and coronary arteries may lead to electrocardiographic changes during a migraine attack. T-wave peak-to-end interval (Tp-e interval) and Tp-e/QT ratio are relatively new markers of ventricular arrhythmogenesis and repolarization heterogeneity...

Here we report the identification of two novel mutations in a previously asymptomatic young man who suffered an out-of-hospital sudden cardiac arrest. During following evaluation, diagnosis of early stage dilated cardiomyopathy was established, while electrocardiogram monitoring showed frequent complex ventricular arrhythmias, incomplete right bundle branch block and prolonged QT duration. No reversible causes explaining the clinical presentation were established and an automatic implantable cardioverter defibrillator was therefore implanted...

BACKGROUND: Cardiostat™ is a single lead ambulatory ECG monitor. Recording is made through 2 electrodes positioned in a lead 1-like configuration. We first validated its accuracy for atrial fibrillation detection compared to a 12-lead ECG. In the second phase of the study, arrhythmia detection accuracy was compared between Cardiostat™ ambulatory ECG and a standard 24 h Holter ECG monitoring. METHOD/RESULTS: Phase one of the study included patients undergoing cardioversion for atrial fibrillation (AF) or atrial flutter...
