Result of the left bundle branch area pacing data collection registry, an international multicenter study of conduction system pacing with a Tendril STS 2088 stylet-driven lead.

Introduction: Left bundle branch area (LBBA) pacing (LBBAP) has been proposed as an alternative therapy option in patients indicated for cardiac pacing to treat bradycardia or heart failure. The aim of the study was to evaluate the safety and effectiveness of LBBAP in patients implanted with a Tendril 2088 stylet-driven lead.

Methods: The international retrospective data collection registry included 11 sites from 5 countries globally.

The Promise of Cilnidipine in Hypertension with Comorbidities: National Consensus Statement: National Consensus Group Comprises Cardiologists, Nephrologists, and Diabetologists from India in a National Meet at New Delhi held on 22 May 2022.

The rapidly increasing burden of hypertension is responsible for premature deaths from cardiovascular disease (CVD), renal disease, and stroke, with a tremendous public health and financial burden. Hypertension detection, treatment, and control vary worldwide; it is still low, particularly in low- and middle-income countries (LMICs). High blood pressure (BP) and CVD risk have a strong, linear, and independent association.

Expert Opinion on the Use of Novel Oral Anticoagulants for Stroke Prevention in Non-valvular Atrial Fibrillation for the Primary Care Setting in India: A Literature Review.

Atrial fibrillation (AF), the most prevalent cardiac arrhythmia encountered in clinical practice, is linked with substantial morbidity and mortality due to accompanying risk of stroke and thromboembolism. Patients with AF are at a five-fold higher risk of suffering from a stroke. Anticoagulation therapy, with either vitamin K antagonists or novel oral anticoagulants (NOACs), is a standard approach to reduce the risk.

Transition from narrow to wide QRS complex during sinus rhythm: What is the mechanism?

A Holter tracing showing transition from narrow QRS to wide QRS after a premature ventricular complex (PVC) during sinus rhythm is presented with explanation of the likely underlying mechanism.

His-bundle pacing versus cardiac resynchronisation therapy: Effect on ECG parameters of repolarization.

Introduction: Cardiac resynchronization therapy (CRT) by biventricular pacing (BiV) may worsen indices of ventricular repolarization. The impact of His bundle pacing (HBP) on repolarization is not well studied in patients with left ventricular systolic dysfunction. The aim of the study is to compare the repolarization parameters in ECG between these two pacing modalities.

Wilms tumor with Mulibrey Nanism: A case report and review of literature.

Background: Mulibrey-Nanism (Muscle-liver-brain-eye Nanism = dwarfism; MUL) is a rare genetic syndrome. The underlying TRIM37 mutation predisposes these children to develop tumors frequently. In the largest published series of MUL, 8% patients were reported to develop Wilms tumor (WT).

Sudden unexpected improvement in the atrioventricular conduction. What is the mechanism?

The 12-lead electrocardiogram (ECG) of a 79-year-old male patient with recurrent pre-syncope showed irregular sinus rhythm with constant PR interval and left bundle branch block (LBBB) with intermittently blocked P waves. The beat following the blocked P wave had a narrower QRS with a shorter PR interval. The phenomenon of bilateral bundle branch block explains the sudden improvement in the atrioventricular conduction.

Regularly irregular, regular and irregularly irregular - All at the same time!

An interesting case of dual tachycardia with coexisting atrial fibrillation and idiopathic left ventricular tachycardia is presented wherein transient ventricular bigeminal rhythm was observed.

Evaluation, Management, and Outcomes of Patients Poorly Responsive to Cardiac Resynchronization Device Therapy.

Background: "Nonresponse" to cardiac resynchronization therapy (CRT) is recognized, but definition(s) applied in practice, treatment(s), and their consequences are little known.

Objectives: The authors sought to assess nonresponse in the prospective, international, ADVANCE CRT registry (Advance Cardiac Resynchronization Therapy Registry).

Methods: Each subject's response was assessed at 6 months post-implantation using site-specific definitions and compared with the independently derived clinical composite score (CCS).

Prevention of sudden cardiac death in athletes, sportspersons and marathoners in India.

The annual incidence of sudden cardiac death (SCD) in athletes is significantly lower than the general population. However, when SCD occurs in an athlete during sporting event or training, it sends shockwaves in the society and raises questions about cardiovascular effects of sports and exercise. This document reviews the causes and mechanism of SCD in sports and exercise in young and older athletes.

Clinical safety and performance of a MRI conditional pacing system in patients undergoing cardiac MRI.

Background: Utilization of cardiac magnetic resonance imaging (cMRI) as an imaging modality in clinical practice is rapidly increasing. More evidence from randomized studies establishing clinical safety and performance of pacing systems in patients undergoing a cMRI scan is needed.

Objectives: The purpose of this prospective, multicenter, randomized study was to demonstrate safety and efficacy of the Accent MRI™ conditional pacing systems (St.

Markedly varying PR intervals during second degree atrioventricular block: possible mechanisms.

A case of second degree atrioventricular block following mitral valve replacement is presented during which varying PR intervals with sudden marked increase in PR interval in consecutive beats was seen. The electrocardiogram is discussed and various hypotheses to explain the possible electrophysiological mechanism are presented.

Entrainment during Ablation of Ischemic Ventricular Tachycardia. What is explanation for Post Pacing Interval shorter than the tachycardia cycle length?

Entrainment mapping of ischemic ventricular tachycardia at a site in the left ventricle where radiofrequency ablation was successful in terminating the tachycardia revealed a post-pacing interval shorter than the tachycardia cycle length. The reason for the same is explained in the current report.
