CONCLUSIONS: We report that CSFP is associated with J-wave and slurring ERPs. However, the clinical significance of these changes needs to be clarified. PMID: 29460660 [PubMed - as supplied by publisher]

Wellens' Syndrome, also known as Coronary T-wave Inversion Syndrome, was identified in the 1980's after a group of patients with unstable angina and characteristic precordial T wave changes on electrocardiogram (ECG) went on to develop large anterior myocardial infarctions. ECG findings are due to critical stenosis in the proximal left anterior descending (LAD) artery. Of patients who present with unstable angina, this ECG pattern is present in 14-18% of cases. Progression from Wellens' Syndrome to anterior myocardial infarction occurs after a mean of 8.5 days and the unique ECG pattern classically presents during chest pain-free periods.

Hernando, D, Garatachea, N, Almeida, R, Casajús, JA, and Bailón, R. Validation of heart rate monitor Polar RS800 for heart rate variability analysis during exercise. J Strength Cond Res 32(3): 716–725, 2018—Heart rate variability (HRV) analysis during exercise is an interesting noninvasive tool to measure the cardiovascular response to the stress of exercise. Wearable heart rate monitors are a comfortable option to measure interbeat (RR) intervals while doing physical activities. It is necessary to evaluate the agreement between HRV parameters derived from the RR series recorded by wearable device...

This article assessed the validity of RR intervals and heart rate variability (HRV) data obtained using an HRM during incremental exercise and artefact correction methods. Eighteen participants completed an active orthostatic test and incremental running V[Combining Dot Above]O2max test, while simultaneous recordings using a Polar V800 HRM and an electrocardiogram were made. Artefacts were corrected by deletion; degree zero, linear, cubic, and spline interpolation; and Kubios HRV software. Agreement was assessed using percentage bias, effect size (ES), intraclass correlation coefficients (ICC), and Bland-Altman limits of a...

Non–electrocardiographic (ECG)-gated computed tomography (CT) of the chest is one of the most commonly performed imaging studies. Although the heart is included in every CT study, cardiac findings are commonly underreported in radiology reports. Left ventricular size is one of the most important prognostic markers in multiple cardiac diseases and can be measured on almost all non–ECG-gated multidetector chest CT studies. This review will discuss the available evidence on different measurements of left ventricular size obtained on non–ECG-gated CT of the chest. Measurement thresholds, technical issues, and...

Written by Pendell Meyers, edits by Steve SmithThis will be too easy for most long-time readers, but if you are at that level, sit back and enjoy noticing how few milliseconds it takes to recognize this thanks to so many prior examples on this blog!I was sent this ECG from EMS with only the information that it belonged to a middle aged male with left shoulder pain.What do you think?There are hyperacute T-waves in leads V1-V6, as well as in leads II, III, aVF. The J-points are all at baseline with the exception of leads V2-V3 which show a small amount of STD (which makes de Winter morphology in the presence of hyperacute T-...

In this study, an improved QRS complex detection method having low complexity is proposed. This method includes two stages as preprocessing and decision making. The preprocessing stage consists of a band-pass digital FIR filter, squaring operation, moving average, normalization steps whereas the decision stage includes only one phase realizing the QRS complex detection. In the preprocessing stage, the unwanted frequency components of the Electrocardiogram (ECG) signal were reduced by using the digital FIR filter. The filtered signal was enhanced with the squaring operation and finally integrated and smoothed by moving aver...

Pharmacopsychiatry DOI: 10.1055/s-0044-102009 Introduction Many antidepressants cause QT prolongation but the classification of cardiac risk of these drugs varies markedly in different published lists. This retrospective study analyzed the correlation of QTc time with amitriptyline and venlafaxine serum level in elderly psychiatric inpatients. Methods Elderly inpatients aged≥65 years for whom venlafaxine or amitriptyline serum level had been measured were selected retrospectively from a therapeutic drug monitoring database and screened for an electrocardiogram measurement at the time of blood withdrawal. The correlation...

The evidence on the association between resting heart rate (HR) and incident atrial fibrillation (AF) is conflicting. Whether change in resting HR is associated with incident AF is unknown. We evaluated 11,545 participants (mean ( ±SD) age: 57 ± 5.7 years) free of AF at baseline (1990-1992). Resting HR was obtained from 10-second electrocardiograms at baseline and 3 years later. AF diagnosis was ascertained from visit electrocardiograms, hospital discharge records, and death certificates through 2013.
