ConclusionThe final results of this study showed that there was no significant difference between the four study groups and arrhythmia status. Therefore, f-QRS was not introduced as an independent predictor of arrhythmia in patients with acute MI.

Authors: Chen J, Xu S, Zhou W, Wu L, Wang L, Li W Abstract The aim of this study was to investigate the effect of exendin-4 (Ex-4) on ventricular arrhythmias and calcium sparks-mediated calcium leak in a myocardial infarction-heart failure model.We studied the influence of exendin-4 on ventricular arrhythmogenesis in a rat myocardial infarction-heart failure model. In vivo arrhythmia studies (electrocardiogram [ECG] telemetry studies), ex vivo arrhythmia studies calcium sparks tests, and analysis of total and phosphorylated ryanodine receptor (RyR) 2 and CaMK-II were carried out in sham group, myocardial infarction...

Publication date: 15 December 2019Source: Life Sciences, Volume 239Author(s): Xuwen Zhai, Xi Qiao, Li Zhang, Dongming Wang, Lijun Zhang, Qilong Feng, Bowei Wu, Jimin Cao, Qinghua LiuAbstractAimsArrhythmogenesis of chronic myocardial infarction (MI) is associated with the prolongation of action potential, reduction of inward rectifier potassium (IK1, Kir) channels and hyper-activity of Calcium/calmodulin-dependent kinase II (CaMKII) in cardiomyocytes. Zacopride, a selective IK1 agonist, was applied to clarify the cardioprotection of IK1 agonism via a CaMKII signaling on arrhythmias post-MI.MethodsMale SD rats were implanted...

Written by Pendell Meyers, submitted by Siva Vittozzi-WongA man in his 30s with history of hypertension, hyperlipidemia, and diabetes presented with chest pain which started 12 hours prior to presentation. The pain was described as pressure, constant for 12 hours, radiating to the jaw, with left arm numbness. Initial vitals were significant for bradycardia at 45 beats per minute.Here is his presenting ECG with active pain:What do you think?Here was the prior EKG on file:The emergency medicine resident (who has received lectures from me on hyperacute T-waves, suble OMI, etc) documented the following interpretation:" In...

Authors: Kuyumcu MS, Özbay MB, Özen Y, Yayla Ç Abstract Objectives. Frontal plane QRS-T angle is a novel marker of myocardial repolarization, and an increased frontal plane QRS-T angle is associated with adverse cardiac outcomes. Slow coronary flow may cause fatal cardiac arrhythmias by causing electrical abnormalities and altering ventricular repolarization. We aimed to evaluate the frontal plane QRS-T angle in patients with slow coronary flow. Design. A total of 60 consecutive patients with slow coronary flow and 60 consecutive patients with normal coronary flow were enrolled into the study. Labo...

CONCLUSIONS: RDN reduced the incidence of PVC, inhibited prolongation of the QTc interval, and reduced VA in the early period following an AMI. These results suggest that RDN might be a therapeutic option in patients with electrical instability after AMI. PMID: 31642212 [PubMed - as supplied by publisher]

Conclusion: Consecutive recording of six single-lead ECGs including Einthoven and Wilson-like leads by a smartwatch is feasible with good ECG signal quality. Thus, this simulated six-lead smartwatch ECG may be useable for the detection of cardiac diseases necessitating more than one ECG lead like myocardial ischemia or more complex cardia arrhythmias.

ConclusionTargeted ablation of TRPV-1/TH positive sympathetic neurons induced by RTX stellate microinjection could suppress ischemia-induced cardiac autonomic imbalances and cardiac electrophysiology instability to protect against AMI-induced VAs.
