<div><h3>Background</h3><div>Sotalol is a class III antiarrhythmic drug used for the management of patients with atrial fibrillation to maintain sinus rhythm. Sotalol-induced QT interval prolongation can be proarrhythmic and is conventionally initiated in an inpatient setting where routine electrocardiographic (ECG) monitoring is available while sotalol reaches the steady state. The emergence of cellular-compatible home ECG devices, such as AliveCor’s Kardia Mobile 6L, which offers 6-lead ECG, has made it possible to accurately measure QT intervals outside the hospital.</div></div><div><h3>Objectives</h3><div>This study aimed to evaluate the safety, feasibility, and patient adherence to protocol-driven, pharmacist-led outpatient sotalol initiation using the Kardia Mobile 6L for remote ECG monitoring and to compare these outcomes with patients completing inpatient sotalol protocol for initiation.</div></div><div><h3>Methods</h3><div>Patients who underwent outpatient sotalol initiation through an antiarrhythmic clinic for the treatment of both atrial and ventricular arrhythmias over a period of approximately 3 years, from September 1, 2020, to June 16, 2023, were retrospectively reviewed and compared with a cohort of inpatients initiated on sotalol. The outpatient cohort had a minimum longitudinal follow-up of 90 days.</div></div><div><h3>Results</h3><div>A total of 263 patients using the outpatient sotalol initiation protocol were compared with 28 age- and sex-matched inpatients who underwent inpatient sotalol initiation. The outpatient cohort included 179 men (68%), with an age of 68.8 ± 10.1 years, CHA<sub>2</sub>DS<sub>2</sub>-VASc score of 3.48 ± 1.43, baseline 12-lead QTc interval of 440.77 ± 33.42 ms, and a left ventricular ejection fraction of 57.4% ± 9.23%. Outpatients were started on a median (minimum-maximum) dose of 120 (80-160) mg of sotalol twice a day (120-mg dose; n = 227; 86.3%) and ended at a median (minimum-maximum) dose of 120 (60-160) mg twice a day (120-mg dose; n = 217; 82.5%). The proportions of patients prescribed low-, moderate-, or high-dose sotalol twice a day (60 mg, 80 mg, 120 mg, and 160 mg) at the end of initiation were similar between the inpatient and outpatient groups (<em>P</em> = 0.5). The majority (98.9%; 260 of 263) of patients completed the 3-day outpatient initiation. Outpatient adherence was high during the 3-day initiation period among patients with varied age and socioeconomic background; 258 patients (98.1%) completed the ECG on day 1, and 240 (91.3%) completed the ECG on day 3. No significant QTc interval prolongation was observed during the outpatient postinitiation study period. There were similar sotalol discontinuation rates within 30 days of initiation in the inpatient vs outpatient cohorts (7% vs 8%; <em>P</em> > 0.90). A total of 17 (6.5%) patients stopped sotalol because of symptomatic bradycardia, and 1 death was observed over a 90-day follow-up period in the outpatient cohort.</div></div><d
背景介绍索他洛尔是一种 III 类抗心律失常药物,用于治疗心房颤动患者以维持窦性心律。索他洛尔引起的 QT 间期延长可能会导致心律失常,通常在住院环境中开始使用,在索他洛尔达到稳定状态时,可进行常规心电图(ECG)监测。与手机兼容的家用心电图设备(如 AliveCor 的 Kardia Mobile 6L,可提供 6 导联心电图)的出现使得在医院外准确测量 QT 间期成为可能:本研究旨在评估使用 Kardia Mobile 6L 进行远程心电图监测的药剂师门诊索他洛尔起始治疗方案的安全性、可行性和患者依从性,并将这些结果与完成住院患者索他洛尔起始治疗方案的患者进行比较:对 2020 年 9 月 1 日至 2023 年 6 月 16 日约 3 年期间通过抗心律失常门诊开始使用索他洛尔治疗房性和室性心律失常的患者进行了回顾性研究,并与开始使用索他洛尔的住院患者进行了比较。门诊病人队列的纵向随访时间至少为 90 天:共有 263 名患者采用门诊索他洛尔起始治疗方案,与 28 名年龄和性别匹配的住院患者采用住院索他洛尔起始治疗方案进行了比较。门诊患者队列中有 179 名男性(68%),年龄为 68.8 ± 10.1 岁,CHA2DS2-VASc 评分为 3.48 ± 1.43,基线 12 导联 QTc 间期为 440.77 ± 33.42 毫秒,左室射血分数为 57.4% ± 9.23%。门诊患者开始服用索他洛尔的中位(最小-最大)剂量为120(80-160)毫克,每天两次(120毫克剂量;n=227;86.3%),结束服用的中位(最小-最大)剂量为120(60-160)毫克,每天两次(120毫克剂量;n=217;82.5%)。住院组和门诊组患者在起始治疗结束时获得低、中或高剂量索他洛尔处方(60 毫克、80 毫克、120 毫克和 160 毫克)的比例相似(P = 0.5)。大多数患者(98.9%;263 人中的 260 人)完成了为期 3 天的门诊初始治疗。不同年龄和社会经济背景的患者在为期 3 天的初始治疗期间的门诊治疗依从性都很高;258 名患者(98.1%)在第 1 天完成了心电图检查,240 名患者(91.3%)在第 3 天完成了心电图检查。在启动后的门诊研究期间,未观察到明显的 QTc 间期延长。住院病人与门诊病人组别在开始治疗后 30 天内的索他洛尔停药率相似(7% vs 8%; P > 0.90)。共有17名(6.5%)患者因出现症状性心动过缓而停用索他洛尔,门诊病人组在90天的随访期间观察到1例死亡病例:结论:通过药剂师主导的抗心律失常门诊启动索他洛尔治疗方案是可行且安全的,不同患者对个人远程心电图的依从性都很高。

Background

Contact force (CF) changes after onset of radiofrequency (RF) delivery are not well understood and often ascribed to catheter instability.

Objectives

This study sought to characterize CF changes during RF-based pulmonary vein (PV) isolation.

Methods

Catheter-tip parameters including CF for all RF sessions were extracted from a novel catheter-mapping system from 6 patients undergoing PV isolation.

Results

Of a total 416 RF sessions, 241 demonstrated progressive increases in CF during RF delivery (group 1). Zero to 5 seconds of RF delivery demonstrated the greatest increase in CF, with no differences between right and left PV sites (2.2 ± 2.2 g vs 1.9 ± 2.3 g, P = 0.26). Subsequent 5-second intervals demonstrated greater increases for right vs left PV sites (eg, 1.2 ± 1.3 g vs 0.5 ± 0.3 g, P = 0.01 for 20 to 25 seconds). CF increment was greater for posterior vs anterior PV sites (3.4 ± 3.1 g vs 1.4 ± 1.4 g, P < 0.001), but similar for roof and floor sites. Higher power and greater impedance drops were associated with greater CF increases. Perpendicular contact had greater CF increases, followed by diagonal and parallel contact. The remaining 175 of 416 sessions demonstrated at least 1 CF decrement, typically occurring after 15 seconds of RF (group 2). This was observed least frequently at inferior PV sites. Except for minor differences in power, there were no differences in CF, tip excursion, and impedance drop between groups.

Conclusions

Progressive CF increase during RF ablation is a distinct phenomenon that likely reflects the “push-back” effect of local myocardial swelling against the catheter tip. This may explain certain catheter-tip behaviors such as tip displacement and instability during ablation.
背景:射频(RF)给药后接触力(CF)的变化尚未得到很好的理解,通常归因于导管不稳定。目的:本研究旨在描述基于rf的肺静脉(PV)分离期间CF的变化。方法:从一种新型导管定位系统中提取6例PV分离患者的导管尖端参数,包括所有RF时段的CF。结果:在总共416次射频治疗中,有241次在射频治疗过程中表现出CF的进行性增加(第1组)。射频治疗0到5秒表现出CF的最大增加,在右侧和左侧PV位点之间没有差异(2.2±2.2 vs 1.9±2.3 g, P = 0.26)。随后的5秒间隔显示右侧PV位点比左侧PV位点增加更大(例如,1.2±1.3 g vs 0.5±0.3 g, P = 0.01,持续20至25秒)。后PV位置的CF增量大于前PV位置(3.4±3.1 vs 1.4±1.4 g, P < 0.001),但屋顶和地板位置相似。更高的功率和更大的阻抗下降与更大的CF增加相关。垂直接触的CF增加幅度最大,其次是对角线和平行接触。在416个疗程中,其余175个疗程至少有1次CF下降,通常发生在射频治疗15秒后(第二组)。这种情况在较低的PV部位观察到的频率最低。除了功率上的微小差异外,两组之间的CF、尖端偏移和阻抗下降没有差异。结论:RF消融过程中进行性CF增加是一种明显的现象,可能反映了局部心肌肿胀对导管尖端的“推回”作用。这可以解释消融过程中导管尖端的某些行为,如尖端位移和不稳定性。

Background

Arrhythmias originating from papillary muscles (PAPs) can be challenging when targeted with catheter ablation. The prevalence and impact of structural abnormalities on PAPs in patients with focal PAP arrhythmias is unknown.

Objectives

The purpose of this study was to analyze, in a consecutive patient series with focal PAP arrhythmias, the impact of structural abnormalities detected by multimodality imaging.

Methods

In a series of 43 consecutive patients with focal PAP arrhythmias referred for ablation, the prevalence and location of structural abnormalities on PAPs were assessed with cardiac magnetic resonance imaging, computed tomographic angiography and intracardiac echocardiography (ICE). Sites of origin of ventricular arrhythmias (VAs) were correlated with structural abnormalities.

Results

On PAPs, late gadolinium enhancement (LGE) was present on cardiac magnetic resonance imaging in 19 of 43 patients, calcifications on computed tomography in 2 of 43 and on ICE in 3 of 43 patients, and increased echogenicity on ICE in 39 of 43 patients. A total of 141 focal PAP arrhythmias were identified, and VA target sites were localized adjacent to areas with increased echogenicity on ICE for 59 of 141 (44%) VAs, adjacent to LGE for 35 of 141 (25%) VAs, and adjacent to calcifications for 14 of 141 (10%) VAs. At least one VA target site was localized to areas of structural abnormalities in 32 of 43 (74%) patients.

Conclusions

Multimodality imaging identifies arrhythmogenic PAPs preprocedurally and in real time during the ablation procedure in most patients. Increased echogenicity, LGE, and calcifications are often seen on PAPs in patients with focal PAP arrhythmias and can indicate the site of origin.
背景:起源于乳头状肌(PAPs)的心律失常在导管消融的靶向治疗中是具有挑战性的。局灶性PAP心律失常患者PAP结构异常的患病率和影响尚不清楚。目的:本研究的目的是分析连续的局灶性PAP心律失常患者系列,多模态成像检测到的结构异常的影响。方法:对43例连续行消融术的局灶性PAP心律失常患者,采用心脏磁共振成像、计算机断层血管造影和心内超声心动图(ICE)评估PAP结构异常的发生率和位置。室性心律失常(VAs)的起源部位与结构异常相关。结果:43例pap患者中,19例出现心脏磁共振晚期钆增强(LGE), 43例中2例出现计算机断层钙化,43例中3例出现ICE钙化,43例中39例出现ICE回声增强。共发现141例局灶性PAP心律失常,141例VAs中有59例(44%)位于ICE回声增强区附近,35例(25%)位于LGE附近,14例(10%)位于钙化区附近。43例患者中有32例(74%)至少有一个VA靶位定位于结构异常区域。结论:多模态成像可在大多数患者术前和消融过程中实时识别致心律失常的pap。在局灶性PAP心律失常患者的PAP上,回声增强、LGE和钙化常被发现,可以提示发病部位。

Background

Prior research suggests Black individuals have a lower risk of atrial fibrillation (AF) than White individuals, but this may be related to the underdetection of AF. Whether this trend persists using highly sensitive methods of AF diagnosis has not been well-studied.

Objectives

The objective of this study was to use cardiac implantable electronic devices (CIEDs) capable of AF diagnosis to compare AF incidence between Black and White individuals.

Methods

This was a retrospective observational study involving Black and White patients who had a CIED implanted between January 1, 2007, and June 1, 2019. Patients with insertable cardiac monitors, insufficient monitoring, or prior AF were excluded. The primary endpoint was the overall adjusted incidence of device-detected AF between Black and White individuals.

Results

Of 441,047 patients with a CIED implanted during the study period, 88,427 patients (mean age, 69 ± 13 years; 80,382 White [91%]; 55,840 male [63%]) were included in analysis. The mean follow-up duration was 2.2 ± 1.7 years, and 35,143 patients (40%) had device-detected AF. The crude incidence of AF was greater among White, compared with Black, individuals (27.95 vs 24.86 cases per 100 person-years, P < 0.001). After adjusting for age, sex, and medical comorbidities, the hazard of AF was similar between Black and White individuals (HR: 1.02; 95% CI: 0.98-1.06). In subgroup analysis by type of CIED, White individuals had a greater hazard of AF in the pacemaker cohort, whereas Black individuals had a greater hazard of AF in the implantable cardioverter defibrillator cohort.

Conclusions

The adjusted hazard of AF was similar between Black and White individuals with CIEDs.
背景:先前的研究表明,黑人患房颤(AF)的风险低于白人,但这可能与房颤的检测不足有关。使用高灵敏度的房颤诊断方法是否会持续这种趋势尚未得到充分研究。目的:本研究的目的是使用能够诊断AF的心脏植入式电子装置(CIEDs)来比较黑人和白人之间的AF发病率。方法:这是一项回顾性观察研究,涉及2007年1月1日至2019年6月1日期间植入CIED的黑人和白人患者。排除了可插入心脏监护仪、监测不充分或有房颤病史的患者。主要终点是黑人和白人之间装置检测到的房颤的总体调整发生率。结果:在研究期间植入CIED的441,047例患者中,88,427例患者(平均年龄69±13岁;White [91%] 80,382;55,840例男性(63%)纳入分析。平均随访时间为2.2±1.7年,35,143例患者(40%)患有器械检测到的房颤。与黑人相比,白人房颤的粗发生率更高(27.95例/ 100人年vs 24.86例/ 100人年,P < 0.001)。在调整了年龄、性别和医疗合并症后,黑人和白人之间的房颤风险相似(HR, 1.02;95% ci: 0.98-1.06)。在按CIED类型进行的亚组分析中,白人在起搏器组中发生房颤的风险更高,而黑人在植入式心律转复除颤器组中发生房颤的风险更高。结论:黑人和白人cied患者AF的校正危险相似。

Background

Chronic kidney disease (CKD) is frequently complicated by arrhythmias, plausibly leading to the increased risk of sudden cardiac death in this population. However, little is known about the association between CKD and third-degree atrioventricular block (3AVB) and need for permanent pacing.

Objectives

This study aimed to investigate the association between CKD and 3AVB.

Methods

In a population-based nested case-control study, patients with 3AVB were identified between July 1995 and December 2018 using Danish administrative registries. Cases were risk set matched 1:5 with controls on sex and birth year. Multivariable Cox regression was used to analyze the association between CKD and 3AVB, with subsequent logistic regression analyses for computation of odds ratios for pacemaker implantation stratified by dialysis or nondialysis CKD.

Results

A total of 31,301 patients with 3AVB were identified and matched with 155,506 controls. The mean age was 74.7 ± 12 years, and 40.2% were female. A significant association was found between CKD and 3AVB after adjustment for comorbidities and potential atrioventricular node blocking agents (HR: 1.83; 95% CI: 1.73-1.93). In stratified analyses, the association was stronger in patients using dialysis compared with nondialysis patients (HR: 7.71; 95% CI: 5.84-10.18; vs HR: 1.73; 95% CI: 1.64-1.83). The odds of pacemaker implantation were lower for patients using dialysis (OR: 0.77; 95% CI: 0.60-0.98) but comparable between patients with nondialysis CKD (OR: 1.04; 95% CI: 0.96-1.12) and patients without CKD.

Conclusions

CKD was independently associated with a higher rate of 3AVB, especially for patients using dialysis.
背景:慢性肾脏疾病(CKD)经常并发心律失常,可能导致该人群心源性猝死的风险增加。然而,CKD与三度房室传导阻滞(3AVB)和需要永久性起搏之间的关系知之甚少。目的:本研究旨在探讨CKD与3AVB之间的关系。方法:在一项基于人群的巢式病例对照研究中,使用丹麦行政登记处在1995年7月至2018年12月期间确定了3AVB患者。病例的风险设置为1:5,性别和出生年份为对照。采用多变量Cox回归分析CKD与3AVB之间的关系,随后进行logistic回归分析,计算透析或非透析CKD分层起搏器植入的优势比。结果:共发现31,301例3AVB患者,并与155,506例对照进行匹配。平均年龄74.7±12岁,女性占40.2%。在调整合并症和潜在房室结阻滞剂后,CKD和3AVB之间存在显著关联(HR: 1.83;95% ci: 1.73-1.93)。在分层分析中,与非透析患者相比,透析患者的相关性更强(HR: 7.71;95% ci: 5.84-10.18;vs HR: 1.73;95% ci: 1.64-1.83)。透析患者植入起搏器的几率较低(OR: 0.77;95% CI: 0.60-0.98),但非透析性CKD患者之间具有可比性(OR: 1.04;95% CI: 0.96-1.12)和无CKD患者。结论:CKD与较高的3AVB率独立相关,尤其是透析患者。
