Use of ivabradine in children with junctional ectopic tachycardia after pediatric cardiac surgery; two-centre experience.
J Arrhythm
December 2024
Department of Pediatric Cardiology Istanbul Mehmet Akif Ersoy Thoracic and Cardiovascular Surgery Training and Research Hospital, University of Health Sciences Istanbul Turkey.
Introduction: Although amiodarone is traditionally used in the treatment of postoperative junctional ectopic tachycardia (JET), the search for new treatments is ongoing. We present our experience with ivabradine at two medical centers.
Materials And Methods: Between January 2022 and January 2023, patients who developed JET after pediatric cardiac surgery were prospectively followed up and documented.
Acute Heart Failure and Complete Heart Block in a Patient with Recurrent Diffuse Large B-Cell Lymphoma: A Case Report.
Am J Case Rep
December 2024
Division of Academic Affairs, Orlando Regional Medical Center, Orlando, FL, USA.
BACKGROUND Cardiac tumors are divided into 2 categories: primary, originating from the heart, and metastatic, which spread to the heart from a different location, with metastatic tumors representing the vast majority. Cardiac tumors, depending on the size and location, can predispose patients to arrhythmic or hemodynamic complications. We present a patient with a history of B-cell lymphoma (DLBCL) in remission for 3 years who developed acute onset congestive heart failure and complete heart block secondary to DLBCL invasion of the myocardium.

Article Synopsis
- * This study creates a computer model to explore how reduced inactivation of calcium channels leads to fluctuating EADs, which can sync up in heart tissue due to the connections between cells, resulting in predictable patterns.
- * The results show that EADs occur after a sudden synchronization (alternans) of heart cells, driven by small changes in pacing rate, which significantly increases the risk of arrhythmias and suggests that abnormal heartbeats can occur without other triggering factors.
Holter Monitoring Analysis of Women Infected with the Human Immunodeficiency Virus.
Curr HIV Res
January 2025
Department of Cardiology, Beijing Ditan Hospital Affiliated to Capital Medical University, Beijing, 100015, China.
Article Synopsis
- The study aimed to evaluate the heart health of women with HIV using Holter monitoring at Ditan Hospital.
- It analyzed data from 35 female HIV-infected patients, revealing various heart rhythm issues, with the most common being sinus rhythm and various premature beats.
- The findings highlighted that Holter monitoring can detect significant ECG abnormalities in HIV-positive patients, potentially allowing for earlier treatment interventions.
Dextrocardia with complete atrioventricular block-the right clinical approach to pace a heart on the right hemithorax: a case report.
J Med Case Rep
October 2024
Cardiology Division, Saint Esprit Kaslik University USEK, Hospital Notre Dame Des Secours, Saint Charbel Street- PO Box # 3, Byblos, 12345, Lebanon.
Article Synopsis
- A 73-year-old woman with a rare condition called dextrocardia (heart on the right side) experienced fainting due to a complete atrioventricular block, leading to a severely low heart rate.
- Extensive tests, including chest X-rays and echocardiograms, confirmed her heart's unusual positioning and showed no major abnormalities aside from her heart condition.
- She successfully underwent surgery to have a dual-chamber pacemaker implanted, helping to address her cardiac issues associated with this uncommon anatomy.
