It has recently been reported that a high-degree right bundle branch block (RBBB) may conceal the electrocardiographic manifestations of the Brugada ECG pattern. An 82-year-old with recent onset palpitations was seen in clinic. The resting ECG showed sinus rhythm, high-degree RBBB, and an irregular idioventricular rhythm. Some fusion beats between sinus rhythm and idioventricular rhythm occurred spontaneously depicting incomplete RBBB pattern and a clear cut elevation of the ST-segment was unveiled, giving rise to a suspicious Brugada ECG pattern. The mechanisms and implications of these findings are discussed.

Prevalence of Arrhythmias in Patients With Coronary Microvascular Dysfunction.
Catheter Cardiovasc Interv
December 2024
Section of Interventional Cardiology, MedStar Washington Hospital Center, Washington, District of Columbia, USA.
Background: Coronary microvascular dysfunction (CMD) is an important cause of angina with nonobstructive coronary arteries (ANOCA). It is unclear whether CMD is associated with arrhythmia.
Aims: This study aimed to evaluate the prevalence of arrhythmias in patients with ANOCA and CMD compared to those in patients with ANOCA without CMD.
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.
Electrocardiographic Changes, Mortality, and Late Period Findings in Methyl Alcohol Poisoning.
J Clin Med
October 2024
Department of Emergency Medicine, Faculty of Medicine, Gaziantep University, Gaziantep 27310, Turkey.
Article Synopsis
- - Methyl alcohol poisoning (MAP) can cause serious health issues and high mortality rates, prompting a study to analyze its effects on electrocardiography (ECG) and long-term complications over a six-year period.
- - The retrospective study involved 227 patients, with a mean age of 43.23 years; findings included significant QTc intervals and various ECG abnormalities, with a mortality rate of 21.6% linked to severe acidosis.
- - Key results showed that patients who died had a notably lower pH and higher QTc distance, indicating severe metabolic disturbances; the study identified new ECG conditions in patients with MAP.
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.
Flecainide Toxicity From Clinical Pharmacology Perspectives.
Cureus
July 2024
Cardiovascular Medicine and Nephrology, Dokkyo Medical University Nikko Medical Center, Nikko, JPN.
Article Synopsis
- - The case involves an 84-year-old woman who experienced flecainide toxicity after being treated for paroxysmal atrial fibrillation, indicated by elevated serum concentration levels and a change in heart rhythm upon hospital admission.
- - After discontinuation of flecainide, her dangerous heart rhythm improved, highlighting the drug's excessive effects based on the calculated half-life.
- - The measured half-life of flecainide was 56.8 hours, significantly longer than the advertised 11 hours, emphasizing the need for careful therapeutic drug monitoring in patients using antiarrhythmic medications.
