Serious outcomes among emergency department patients with presyncope: A systematic review

Academic Emergency Medicine, Volume 33, Issue 1, January 2026.
Abstract Background Syncope is transient loss of consciousness, and in presyncope, patients experience same prodromal symptoms without losing consciousness. While studies have extensively reported the risk of serious outcome among emergency department (ED) syncope, the outcome for patients with presyncope and their management are not well studied.

A surgical resection case of myxoma arising from the posterior wall of the left atrium complicated with complete atrioventricular block

Journal of Cardiothoracic Surgery
An 80-year-old female was referred to our institution due to transient right upper limb weakness. Transthoracic and transesophageal echocardiography revealed a tumor in the left atrium. The tumor was attached to the posterior wall of the left atrium near

Transient unexpected improvement of AV conduction: What is the mechanism? [PDF]

, 2006
This ECG was recorded from a 93 year old patient with a previously documented third degree AV block and an underlying LBBB. The twelve lead ECG demonstrates sinus bradycardia at a rate of 52 beats per minute, a PR interval of 230 milliseconds, and a ...

Outcomes of Supraclavicular Access in Temporary Pacemaker Implantation

Annals of Noninvasive Electrocardiology, Volume 31, Issue 1, January 2026.
This study compared supraclavicular versus infraclavicular venous access for temporary pacemaker implantation in 3569 patients. Supraclavicular access showed fewer complications, higher first‐attempt success, shorter procedure time, and improved complication‐free survival.

Is Left Bundle Branch Pacing Feasible in Patients With Ventricular Septal Defect?

Annals of Noninvasive Electrocardiology, Volume 31, Issue 1, January 2026.
This report presents two cases of left bundle branch pacing (LBBP) implantation in patients with perimembranous ventricular septal defect (pmVSD) and provides a novel approach to guide lead placement using both angiography and electroanatomic mapping, which ensures accuracy and reduces potential complications.

Central nervous system involvement in cardiac amyloidosis: Redefining the heart‐brain axis

European Journal of Clinical Investigation, Volume 56, Issue 1, January 2026.
Central nervous system involvement in cardiac amyloidosis. Amyloidosis is a systemic disease that can directly affect the central nervous system. Furthermore, the amyloid cardiomyopathy can indirectly affect the central nervous system by inducing systemic hypoperfusion and increasing the risk of acute ischaemic stroke.

Cellular Senescence, Inflammaging and Cardiovascular Disease

Immunological Reviews, Volume 337, Issue 1, January 2026.
ABSTRACT Aging is the most important yet unmodifiable risk factor for cardiovascular disease (CVD). As a result, targeting cardiovascular aging has emerged as a promising strategy to promote long‐term cardiovascular health. This review summarizes current knowledge on the effects of aging within the cardiovascular system as well as systemic processes ...

Premature Ventricular Contractions From the Proximal Left Anterior Fascicle: Insight From the Electrophysiologic and Anatomic Parameters

Journal of Cardiovascular Electrophysiology, Volume 37, Issue 1, Page 7-16, January 2026.
ABSTRACT Introduction Premature ventricular contractions (PVCs) originating from the proximal left anterior fascicle (LAF) are rarely discussed. We aimed to describe the characteristics and ablation outcome of PVCs originating from the proximal LAF and propose a stepwise approach.
