Aligning goals with care: Advance directives in older adults with implantable cardioverter ‐defibrillators
ConclusionsMost Veterans had a documented advance directive, but a significant minority did not. Simple frailty and cognitive screening tools can rapidly identify patients for whom discussion of advance directives is especially important. (Source: Pacing and Clinical Electrophysiology : PACE)

2:1 electronic AV block due to inappropriate automatic post ‐ventricular atrial refractory period extension
AbstractA 16-year-old female with dual-chamber pacemaker (Medtronic Azure XT DR), due to symptomatic third-degree congenital atrioventricular (AV) block, presented to our ambulatory with dizziness and presyncopal episodes preceded by prodromes, occurring over the last few months. The device was programmed in DDD mode with an upper rate of 150  bpm. A head-up Tilt Test (HUTT) revealed the unexpected emergence of 2:1 electronic AV block at a sinus rate of 130 bpm.

Functional substrate mapping of atrium in patients with atrial scar: A novel method to predict critical isthmus of atrial tachycardia
AbstractAtrial tachycardia (AT) is a common rhythm disorder, especially in patients with atrial structural abnormalities. Although voltage mapping can provide a general picture of structural alterations which are mainly secondary to prior ablations, surgery or pressure/volume overload, data is scarce regarding the functional characteristics of low voltage regions in the atrium to predict critical isthmus of ATs. Recently, functional substrate mapping (FSM) emerged as a potential tool to evaluate the functionality of structurally altered regions in the atrium to predict critical sites of reentry. Current evidence suggested ...

Autonomic modulation of heart rate during physical activity in pregnant women: A systematic review of literature
ConclusionMost studies demonstrate benefits heart rate in pregnant women, but limited research makes it hard to compare specific types of exercise and larger studies are needed to identify the best exercise. (Source: Pacing and Clinical Electrophysiology : PACE)

His potential injury as the end point of screwing by a continuous recording technique in His bundle pacing: A case report
AbstractBackgroundHis bundle pacing (HBP) engaged electrical activation of both ventricles  by stimulating the His-Purkinje network, which could avoid marked ventricles dyssynchrony. The lead was given three to five clockwise rotations at the site with the His potential to anchor the interventricular septum. In 2018, the Multicenter His Bundle Pacing Collaborative Working Group recommend ed that the His bundle capture threshold should be lower than 2.5 V/1 ms in non-pacing-dependent patients, and pacing-dependent patients should have a lower adjacent ventricular capture threshold as self-backup. Therefore, to avoid safe...

Asymmetric dimethylarginine correlates with indicators of prethrombotic state in patients with nonvalvular atrial fibrillation
ConclusionsOur findings suggested that ADMA correlated with the prethrombotic state in NVAF and that reduction of ADMA levels in NVAF patients may be a novel therapeutic strategy for thrombosis risk reduction. (Source: Pacing and Clinical Electrophysiology : PACE)

Prevention of esophageal lesions during atrial fibrillation catheter ablation using esophageal temperature monitoring: A systematic review and meta ‐analysis
ConclusionsThe use of ETM does not reduce the incidence of EDELs during RF AF ablation. The higher energy delivered on the posterior wall is likely attributable to a false sense of safety that may explain the lack of benefit of ETM. Further randomized controlled trials are needed to provide conclusive results. (Source: Pacing and Clinical Electrophysiology : PACE)

Informational letters or postcards to initiate remote monitoring among veterans with pacemakers and implantable cardioverter ‐defibrillators: A randomized, controlled trial
ConclusionsThis randomized trial showed no significant difference in the proportion of chronically non-adherent patients who sent an RM transmission after receiving a low-cost postcard or a detailed, higher-cost letter encouraging their participation in RM. However, as only a minority of patients responded to either, further work is needed to engage patients in the life-saving benefits of RM. (Source: Pacing and Clinical Electrophysiology : PACE)

Elucidating left atrial electrical potential with microelectrode catheter: A case of coronary sinus ostial atresia with small persistent left superior vena cava
AbstractA 51-year-old woman presented with recurring palpitations. Electrocardiography revealed narrow QRS tachycardia with short RP configuration. Computed tomography showed coronary sinus (CS) ostial atresia along with a small persistent left superior vena cava (PLSVC). Electrophysiological study identified the retrograde earliest atrial activation site (EAAS) at the CS ostium without decremental properties, and para-Hisian pacing suggested retrograde atrioventricular nodal conduction. Using a 1.6-Fr microelectrode catheter distally placed in the CS via the PLSVC, EAAS was confirmed within the left atrium, not the CS ost...
