AI Article Synopsis
- This systematic review evaluates how common pacemaker-induced cardiomyopathy (PICM) is in patients with right ventricular pacing and what factors might predict its occurrence.
- A thorough literature search was conducted, examining studies from various academic databases up until October 2021, ultimately including 20 studies with over 5,300 patients.
- The findings indicate that the average incidence of PICM is around 25.7%, with risk factors including male gender, older age, longer QRS duration, and the extent of RV pacing.
Article Abstract
Introduction: This systematic review aims to evaluate the incidence and predictors of pacemaker-induced cardiomyopathy (PICM) in patients undergoing right ventricular pacing.
Areas Covered: A literature review was conducted using MeSH terms (Right ventricular pacing, Pacemaker-related cardiomyopathy, Pacemaker-induced cardiomyopathy) in PubMed, EMBASE, Web of science CINAHL, and the Cochrane Library until October 2021. All data reporting the incidence of PICM after implantation of right-sided pacemakers or implantable cardioverter-defibrillator (ICD) were retrieved from the eligible studies.
Expert Opinion: Out of 3,625 articles, 20 studies met the inclusion criteria that included 5,381 patients. . The mean age of the patients ranged between 55.8 ± 13.5 and 77.4 ± 10.8 years. The mean incidence of PICM was 25.7%. Mean ejection fraction (EF) at baseline ranged from 48 ± 1% and 62.1 ± 11.2%, while mean EF at follow-up ranged between 33.7 ± 7.4% and 53.2 ± 8.2%. Three studies reported a decline of >20% EF at follow-up. RV pacing was associated with a considerable risk of PICM, with biological factors, such as male gender, old age, increased QRS duration, and chronic RV pacing burden playing an important role in the development of disease.

Department of Cardiology, Hangzhou First People's Hospital, #261 Huansha Road, Hangzhou, 310000, Zhejiang Province, China.
Background: To investigate the optimization of leadless pacemaker placement and to assess its impact on heart synchronization and tricuspid regurgitation.
Results: A clinical trial was conducted involving 53 patients who underwent leadless pacemaker implantation at the Second Affiliated Hospital of Zhejiang University School of Medicine and Hangzhou First People's Hospital between March 2022 and February 2023. Implantation site localization was determined using the 18-segment method under RAO 30° imaging.
Deep Septal Pacing for Pacemaker-Induced Cardiomyopathy.

Introduction: Right ventricular (RV) pacing can impair left ventricular function and cause heart failure, known as pacing-induced cardiomyopathy (PICM). Upgrade to cardiac resynchronization (CRT) is its usual treatment; recently left bundle branch area pacing (LBBAP) has emerged as a potential alternative. Deep septal pacing (DSP), a simplified alternative to LBBAP, is still able to achieve narrower paced QRS than during conventional RV pacing.

Background: Pacemaker and implantable cardioverter-defibrillator (ICD) lead placement traditionally uses fluoroscopy, often with inaccurate lead placement on the free wall rather than on the ventricular septum, with associated longer QRS duration and pacemaker-induced cardiomyopathy while exposing staff and patients to radiation.
Objective: We sought to determine whether transesophageal 3-dimensional echocardiography (3DE) guidance improves lead placement accuracy in the ventricular septum, results in shorter paced QRS durations, and reduces fluoroscopy exposure.
Methods: In a single-center case-control study, 3DE guided right ventricular or atrial pacemaker and ICD leads to the desired location, with fluoroscopy used per operator preference.

Left bundle branch area pacing is currently the most common form of physiological pacing prior to His bundle pacing. It is intended to prevent or correct the development of pacemaker-induced cardiomyopathy and is being used more and more frequently. In order to be able to perform this successfully, knowledge regarding the specific anatomy and radiological anatomy as well as the ECG criteria for left bundle branch pacing is required in addition to knowledge of the tools.

Article Synopsis
- Heart failure (HF) is a serious health issue that has high rates of illness and death, with electrical conduction problems being a key factor in its progression.
- Conduction system pacing (CSP) is a new treatment method that includes techniques like His bundle pacing and left bundle branch area pacing, recommended for certain patients despite mainly being supported by observational studies.
- There are significant challenges in implementing CSP, such as difficulties with lead implantation and the need for better tools, making future large-scale randomized controlled trials necessary for improving treatment strategies for HF patients.
