Accelerated idioventricular rhythm after left bundle branch pacing lead implantation.
J Electrocardiol
December 2024
Department of Cardiovascular Surgery, Kobari General Hospital, Chiba, Japan.
Article Synopsis
- Premature ventricular contractions (PVCs) with right bundle branch block suggest proximity of the lead to the left bundle branch (LBB) region during implantation.
- The article discusses a case where accelerated idioventricular rhythm (AIVR) was observed immediately after LBB lead deployment, a phenomenon not previously reported.
- AIVR serves as an additional indicator that the lead has successfully reached the LBB area in a patient with complete atrioventricular block.

18-Month-Old with Lethargy and Accelerated Idioventricular Rhythm in Prehospital Setting: A Case Report.
Prehosp Emerg Care
October 2024
Albany Medical College, Albany, New York.
Article Synopsis
- A case of accelerated idioventricular rhythm (AIVR) was identified in an 18-month-old infant experiencing lethargy and respiratory distress, showcasing the importance of prehospital ECG monitoring.
- AIVR is characterized by >3 monomorphic beats and is generally well-tolerated, often occurring in pediatric patients with congenital heart diseases but can be benign in other cases.
- Continuous ECG monitoring in critically ill children can help detect dysrhythmias like AIVR in emergency situations, leading to timely management and understanding of the patient's condition.
Intracardiac echocardiography-guided catheter ablation of highly symptomatic accelerated idioventricular rhythm originating from the right ventricular apical diverticulum.
Pacing Clin Electrophysiol
October 2024
Department of Cardiology, Yan'an Hospital, Kunming Medical University, Kunming, China.
Article Synopsis
- - Ventricular diverticula are pouch-like structures that occur when heart muscle bulges outward from the inner heart lining, often causing no symptoms in patients.
- - These structures, while usually muscle-based, can lead to heart rhythm issues due to disruptions in the heart's structure.
- - The case discussed focuses on a rare right ventricular apical diverticulum (RVAD) that caused significant heart rhythm problems, successfully treated with a specialized procedure called catheter ablation, with no further issues reported afterward.

J Pharmacol Toxicol Methods
December 2023
Hannover Heart Rhythm Center, Department of Cardiology & Angiology, Hannover Medical School, Germany; Center for Electrophysiology Bremen, Bremen, Germany. Electronic address:
Article Synopsis
- Researchers tested three different ways to analyze heart data from monkeys to see how well they could find heart problems called arrhythmias.
- Two methods that used computer programs found more arrhythmias than the manual method, with the second method being more accurate at identifying specific types of arrhythmias.
- The second method also saved a lot of time and effort compared to the manual check, making it a good option for studying heart health in other animal tests.
Presumed primary cardiac mast cell tumor, pericardial effusion, and arrhythmia in a dog.
J Vet Cardiol
June 2023
Angell Animal Medical Center, 350 South Huntington Avenue, Boston, MA 02130, USA.
Article Synopsis
- - A 13-year-old spayed border collie cross was diagnosed with pericardial effusion, arrhythmia, and a suspected cardiac mass, with echocardiograms indicating severe heart muscle changes.
- - The dog exhibited an accelerated idioventricular rhythm and occasional ventricular tachycardia on ECG, suggesting issues possibly linked to heart structure changes caused by a tumor.
- - Cytology identified atypical mast cells in the pericardial fluid; the dog was euthanized and postmortem confirmed a mast cell tumor infiltrating the heart and metastasizing to other organs, marking it as a unique case of this kind in dogs.
Article Synopsis
- Accelerated idioventricular rhythm (AIVR) that starts from the right bundle branch (RBB) is an uncommon type of heart rhythm disturbance.
- Researchers studied the activation of both the RBB and the surrounding heart muscle during RBB-AIVR to understand where the arrhythmia originates and how it spreads.
- Using radiofrequency ablation on the identified pathway effectively treated and eliminated the AIVR.
Wide complex rhythm in a well neonate: Where are the P waves?
Cardiol Young
October 2023
Department of Paediatric Cardiology, University Hospital of Wales, Cardiff, UK.
Article Synopsis
- A newborn displayed a variable broad QRS complex rhythm that was first observed as occasional escape beats right after birth.
- Continuous monitoring suggested characteristics of pre-excitation but ultimately indicated a broad QRS rhythm with isorhythmic atrioventricular dissociation, likely from a ventricular origin.
- The arrhythmia was effectively managed with the medications flecainide and propranolol, leading to enhanced cardiac function as seen on echocardiogram.

March 2023
Cardiac Electrophysiology Research Center, Rajaie Cardiovascular Medical and Research Center, Iran University of Medical Sciences, Tehran, 1995614331, Iran.
Article Synopsis
- Accelerated idioventricular rhythm (AIVR) is a slow ventricular arrhythmia often seen in conditions like coronary artery disease and usually doesn't require specific treatment.
- A case was reported of a 76-year-old man who developed AIVR after cardiac surgery due to hypothermia, leading to temporary hemodynamic instability, despite good initial recovery.
- The patient was successfully treated by warming him up to 35ºC, after which his heart rhythm returned to normal, emphasizing the importance of addressing hypothermia to prevent arrhythmias post-surgery.

Frequent accelerated idioventricular rhythm in an otherwise healthy child: a case report and review of literature.
BMC Cardiovasc Disord
January 2023
Department of Cardiology, University Hospital "Sveti Duh", Zagreb, Croatia.
Article Synopsis
- AIVR (Accelerated Idioventricular Rhythm) is a type of heart rhythm commonly found in children, especially those with existing heart or systemic issues, but is usually benign in otherwise healthy kids.
- The literature shows limited treatment success, with most guidelines being vague, and only a few instances of serious complications in children with high daily AIVR burden.
- In a case study of an asymptomatic 11-year-old boy with incidentally discovered AIVR, successful treatment through an electrophysiological procedure led to a return to normal heart rhythm.
New-Onset Accelerated Idioventricular Rhythm During Dental Rehabilitation.
Anesth Prog
December 2022
University of Wisconsin School of Medicine and Public Health, Department of Anesthesiology, Division of Pediatric Anesthesiology, Madison Wisconsin.
Article Synopsis
- Accelerated idioventricular rhythm has been observed during general anesthesia but not previously recognized during the reversal of neuromuscular blockade using neostigmine and glycopyrrolate.
- An 8-year-old boy developed this rhythm immediately after receiving the reversal agents during dental rehabilitation and experienced intermittent occurrences during recovery without any symptoms.
- The incident was benign, with the patient remaining hemodynamically stable and the arrhythmia resolving on its own after several hours of monitoring, suggesting that the reversal process might trigger this rhythm in certain patients.

Subclinical Arrhythmias and Conduction Disturbances in Children with Myopericarditis: A 24-hour Holter Monitorization Study.
Eurasian J Med
October 2022
Division of Pediatric Cardiology, Department of Pediatrics, Atatürk University Faculty of Medicine, Erzurum, Turkey.
Article Synopsis
- This study investigates arrhythmias and conduction disturbances in children with myopericarditis, a condition often considered benign but lacking specific research on heart rhythm issues.
- The researchers reviewed medical records of children diagnosed with myopericarditis from 2016 to 2021 and used both surface electrocardiography and 24-hour Holter monitoring for assessment.
- Results showed that while troponin levels were significantly elevated at admission, surface ECGs were normal for all patients, and only 4 out of 27 showed clinically insignificant arrhythmias during Holter monitoring, reinforcing myopericarditis as a generally benign condition in this population.

Article Synopsis
- * Out of 25 participants, 20% had to discontinue HCQ due to QT prolongation or other heart rhythm issues, with notable cases occurring primarily in those over 50 years old.
- * The study concluded that regular heart monitoring can detect early QT prolongation, allowing for timely discontinuation of HCQ, and indicated that young, healthy individuals experience a lower risk of significant QT prolongation.
Post-return of spontaneous circulation (ROSC) Accelerated Idioventricular Rhythm in the Setting of Severe Pancreatitis and Hyperkalemia.
