Ischemic QRS prolongation as a biomarker of myocardial injury in STEMI patients.

Ann Noninvasive Electrocardiol 2019 Jan 28;24(1):e12601. Epub 2018 Sep 28.

Department of Clinical Physiology and Nuclear Medicine, Skåne University Hospital and Lund University, Lund, Sweden.

Background: Patients with acute coronary occlusion (ACO) may not only have ischemia-related ST-segment changes but also changes in the QRS complex. It has recently been shown in dogs that a greater ischemic QRS prolongation (IQP) during ACO is related to lower collateral flow. This suggests that greater IQP could indicate more severe ischemia and thereby more rapid infarct development. Read More

Supraventricular arrhythmia with discordant electrocardiographic features: What is the arrhythmia mechanism?

Ann Noninvasive Electrocardiol 2018 Sep 28:e12595. Epub 2018 Sep 28.

Arrhythmia & EP Research Center, IRCCS Humanitas Research & University Hospital, Rozzano, Milan, Italy.

Junctional and AV nodal reentrant tachycardia share common electrocardiographic features, but they differ in their management and outcomes after catheter ablation. This case concerns a 60-year-old female who presented with recurrent episodes of a relatively slow, regular supraventricular arrhythmia. Electrocardiographic features of the arrhythmia were discordant regarding its underlying mechanism. Read More

Electro-vectorcardiographic demonstration of rate-independent transient left posterior fascicular block.

Ann Noninvasive Electrocardiol 2018 Sep 26:e12600. Epub 2018 Sep 26.

Heart Center, Faculty of Medicine and Life Sciences, Tampere University Hospital, University of Tampere, Tampere, Finland.

Left posterior fascicular block (LPFB) is a rare intraventricular conduction disorder of rare occurrence, especially as an isolated entity. Its transient form is even rarer and maybe rate-independent or rate-dependent intermittent LPFB (phase 3 block, tachycardia-dependent and phase 4 block or bradycardia-dependent). We present a case of a young adult male whose baseline ECG/VCG showed the typical LPFB pattern. Read More

Comparison of the prognostic role of Q waves and inverted T waves in the presenting ECG of STEMI patients.

Ann Noninvasive Electrocardiol 2019 Jan 6;24(1):e12585. Epub 2018 Sep 6.

Faculty of Medicine and Life Sciences, University of Tampere, Tampere, Finland.

Background: Both Q waves and T-wave inversion (TWI) in the presenting ECG are associated with a progressed stage of myocardial infarction, possibly with less potential for myocardial salvage with reperfusion therapy. Combining the diagnostic information from the Q- and T-wave analyses could improve the prognostic work-up in ST-elevation myocardial infarction (STEMI) patients.

Methods: We sought to determine the prognostic impact of Q waves and TWI in the admission ECG on patient outcome in STEMI. Read More

Second-degree interatrial block: Brief review and concept.

Ann Noninvasive Electrocardiol 2018 Nov 2;23(6):e12583. Epub 2018 Sep 2.

National Academy of Medicine, Buenos Aires, Argentina.

The advanced interatrial block (A-IAB) (P ≥ 120 ms plus ± pattern in II, III and aVF) corresponds at atrial level, to right or left advanced bundle branch block at ventricular level, and it is well known that these patterns may be seen transiently in relation to taquicardia or bradycardia (tachycardia or bradycardia dependent right or left bundle branch block). We present for the first time, the same phenomenon at atrial level. In one case, the A-IAB appears in relation to tachycardization and in the other disappears during a pause induced by ventricular premature complex. Read More

Association between serum cotinine levels and electrocardiographic left atrial abnormality.

Ann Noninvasive Electrocardiol 2019 Jan 27;24(1):e12586. Epub 2018 Aug 27.

Epidemiological Cardiology Research Center (EPICARE), Department of Epidemiology and Prevention, Wake Forest School of Medicine, Winston Salem, North Carolina.

Background: Although the harmful effect of tobacco exposure on cardiovascular disease (CVD) and its risk factors are well established, the constituents of cigarette-smoke and the pathophysiological mechanism involved are unknown. Recently, deep terminal negativity of P wave in V1 (DTNPV1) has emerged as a marker of left atrial abnormality that predicts atrial fibrillation, stroke, and death due to all-cause or CVD. Therefore, we examined the association between serum cotinine levels with abnormal DTNPV1 using the Third National Health and Nutrition Examination Survey. Read More

An investigation on the influence of yogic methods on heart rate variability.

Ann Noninvasive Electrocardiol 2019 Jan 22;24(1):e12584. Epub 2018 Aug 22.

Department of Human Consciousness & Yogic Sciences, Mangalore University, Mangalagangotri, India.

Background: The role of underlying mechanisms of yogic strategies which exert beneficiary effects on cardiac autonomic control is poorly understood. We have performed heart rate variability (HRV) analysis on subjects performing yogic methods and control subjects who mimic them through paced breathing and focused attention tasks using external cues.

Methods: Heart rate (HR) time series is generated from electrocardiogram measured from subjects of yogic group (YG); performing yogic practices (n = 15), paced breathing group (PBG); involved in breathing exercises cued at breathing rates (BR) from 3 to 15 cycles per minute (cpm) (n = 23), normal breathing group (NBG) under regular breathing (n = 15), and subjects performing three different cognitive tasks designated as focused attention group (FAG), (n = 24).
