Introduction

Several electrocardiograph markers are proposed as predictors of life-threatening arrhythmia in Brugada Syndrome, including the aVR sign. However, results of previous studies were inconsistent. Therefore, we aim to determine whether the aVR sign can predict sudden cardiac death in BrS patients.

Methods

We extracted data from PubMed, Cochrane, and EBSCO using MeSH keywords “Brugada syndrome, sudden cardiac death, arrhythmia”. Inclusion criteria include cohorts from the last 10 years of the BrS population with the aVR sign as a predictor. We excluded patients with channelopathies other than Brugada syndrome and low-quality studies. We assessed the quality of studies using the Newcastle-Ottawa Scale. Data will be presented as odds ratios with 95 % confidence intervals. The endpoint is life-threatening arrhythmia resulting in sudden cardiac death.

Results

From 7 cohort studies (1763 patients), R-wave amplitude ≥3 mV in lead aVR has increased risk of sudden cardiac death (OR = 2.15, 95 % CI = 1.56–2.98, I² = 0 %). R/q ratio ≥0.75 in aVR is also associated with increased risk. All studies were considered good quality based on the Newcastle-Ottawa scale. These markers may be integrated with other factors to identify the high-risk patients.

Conclusion

aVR sign can predict sudden cardiac death in Brugada syndrome and this marker may be considered for risk assessment and lead the management strategy for better prevention.

介绍：几种心电图指标被提出作为Brugada综合征危及生命的心律失常的预测指标，包括aVR体征。然而，以往的研究结果并不一致。因此，我们的目的是确定aVR标志是否可以预测BrS患者的心源性猝死。方法：我们使用MeSH关键词“brugada综合征、心源性猝死、心律失常”从PubMed、Cochrane和EBSCO中提取数据。纳入标准包括过去10年BrS人群的队列，aVR标志作为预测因子。我们排除了除Brugada综合征和低质量研究外的其他通道病变患者。我们使用纽卡斯尔-渥太华量表评估研究的质量。数据将以95%置信区间的比值比表示。终点是危及生命的心律失常，导致心源性猝死。结果：在7项队列研究（1763例患者）中，aVR导联r波振幅≥3mv会增加心源性猝死的风险（OR = 2.15, 95% CI = 1.56-2.98, I2 = 0%）。aVR的R/q比值≥0.75也与风险增加相关。根据纽卡斯尔-渥太华量表，所有研究都被认为质量良好。这些标志物可与其他因素结合识别高危患者。结论：aVR标志可预测brugada综合征心源性猝死，可作为brugada综合征的风险评估指标，指导治疗策略，更好地预防。

At the beginning of the last century, quinidine had been shown to be highly effective in the management of atrial fibrillation and soon after, of ventricular arrhythmias. At the end of the same century, quinidine was quickly abandoned, and its manufacturing ceased, resulting in limited accessibility across numerous countries. Paradoxically, this decline in use occurred alongside accumulating evidence supporting quinidine's therapeutic benefit in managing rare, life-threatening ventricular arrhythmias occurring in patients with no organic heart disease (Idiopathic ventricular fibrillation, Brugada syndrome, Early repolarization syndrome, Short QT syndrome, Multifocal ectopic Purkinje-related premature contractions), as well as in those with organic heart disease involving the Purkinje network (acute myocardial infarction and hypertrophic cardiomyopathy). The present review will extensively deal with all these topics.

在上个世纪初，奎尼丁已被证明对房颤和室性心律失常的治疗非常有效。在同一世纪末，奎尼丁很快被放弃，其生产停止，导致许多国家的可及性有限。矛盾的是，在使用量下降的同时，越来越多的证据支持奎尼丁在治疗非器质性心脏病（特发性心室颤动、Brugada综合征、早期复极综合征、短QT期综合征、多灶异位浦肯病相关性早搏）患者中发生的罕见、危及生命的室性心律失常方面的治疗益处。以及那些涉及浦肯野网络的器质性心脏病，如急性心肌梗死后或肥厚性心肌病患者。本文将广泛讨论所有这些问题。

A 64-year-old male with oropharyngeal carcinoma experienced recurrent syncope and hypotension due to neoplastic compression of the right carotid space. Despite initial treatment with atropine and fluid resuscitation, the patient continued to experience presyncope and hypotensive events. After treatment with a conventional dual-chamber pacemaker failed, the use of closed-loop stimulation (CLS) successfully resolved the syncope episodes. This case highlights the efficacy of CLS pacing in managing reflex syncope caused by extrinsic neoplastic compression of the carotid sinus. The CLS algorithm, by detecting pre-syncopal phases and increasing heart rate proactively, offers a significant advantage over conventional pacing in preventing syncope.

64岁男性口咽癌复发晕厥和低血压，由于肿瘤压迫右颈动脉空间。尽管最初使用阿托品和液体复苏治疗，但患者继续出现晕厥前和低血压事件。在常规双室起搏器治疗失败后，使用闭环刺激（CLS）成功地解决了晕厥发作。本病例强调了CLS起搏治疗由颈动脉窦外源性肿瘤压迫引起的反射性晕厥的疗效。CLS算法通过检测晕厥前阶段和主动增加心率，在预防晕厥方面比传统起搏具有显著优势。

Incessant supraventricular tachycardias leading to arrhythmia induced cardiomyopathy (AIC) is not uncommon. We report one such case of an incessant multidrug resistant focal left atrial tachycardia (AT) in a child who presented with AIC. During electrophysiology study this tachycardia was localized to the left atrial appendage (LAA) but, endocardial ablation at this site caused only temporary suppression of arrhythmia. The epicardial ablation at the site adjacent to the endocardial area proficiently terminated the tachycardia and improved the left ventricular function within the first 48 hours itself. Thus, this case report emphasizes the epicardial ablation of rare epicardial AT arising from LAA.

持续的室上性心动过速导致心律失常性心肌病（AIC）并不罕见。我们报告一个这样的情况下，一个持续多药耐药局灶性左房性心动过速（AT）在一个儿童谁提出了AIC。在电生理学研究中，这种心动过速定位于左心耳（LAA），但在该部位进行心内膜消融仅能暂时抑制心律失常。心外膜邻近心内膜区域的消融术可有效终止心动过速，并在最初48小时内改善左心室功能。因此，本病例报告强调由LAA引起的罕见心外膜AT的心外膜消融。
