The dynamics of GABA signaling: Revelations from the circadian pacemaker in the suprachiasmatic nucleus

open access: yesFrontiers in neuroendocrinology (Print), 2016
Virtually every neuron within the suprachiasmatic nucleus (SCN) communicates via GABAergic signaling. The extracellular levels of GABA within the SCN are determined by a complex interaction of synthesis and transport, as well as synaptic and non-synaptic

Forecasting heart failure: Seasonal alignment of heart failure outcomes in New York

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 819-831, April 2025.
Abstract Background Seasonal variations have been observed in heart failure (HF) hospitalization. Numerous explanatory mechanisms have been proposed, but no prior studies have examined potential contributors directly. Our objective was to identify specific factors that could contribute to seasonal variability using a large longitudinal dataset of HF ...

Incident heart failure: comparing management and outcome in primary and hospital settings in Western Sweden 2008–2017

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 832-838, April 2025.
Abstract Aim Heart failure (HF) is a highly prevalent condition managed in both primary care (PC) and hospital care (HC)‐based settings. HF patients managed in these two settings may differ in their demography, comorbidities and outcomes, so we aimed to compare the patient management in PC and HC in the Västra Götaland Region (VGR) in Sweden.

Cardiac Device Algorithms for Optimal Outcomes in Patients with Sick Sinus Syndrome [PDF]

open access: yes, 2013
Sick sinus syndrome (SSS) is a relatively common chronic condition affecting the electrical conduction system of the heart. In the absence of any reversible cause of SSS, the most effective treatment is implantation of a permanent pacemaker to maintain ...

A preliminary assessment of the effects of ATI-2042 in subjects with paroxysmal atrial fibrillation using implanted pacemaker methodology

open access: yes, 2009
Aims ATI-2042 (budiodarone) is a chemical analogue of amiodarone with a half life of 7 h. It is electrophysiologically similar to amiodarone, but may not have metabolic and interaction side effects.

Transthyretin amyloid cardiomyopathy: Literature review and red‐flag symptom clusters for each cardiology specialty

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 955-967, April 2025.
Abstract Wild‐type transthyretin amyloid cardiomyopathy (ATTRwt‐CM) is a progressive and infiltrative cardiac disorder that may cause fatal consequences if left untreated. The estimated survival time from diagnosis is approximately 3–6 years. Because of the non‐specificity of initial symptom manifestation and insufficient awareness among treating ...

Concealed malfunction of the temporary pacemaker

open access: yesIndian Pacing and Electrophysiology Journal, 2006
The 12-lead ECG shows sequential atrial and ventricular pacing (Figure 1A). A tracing, obtained simultaneously during pacemaker interrogation, disclosed pacemaker functioning as VDD mode (Figure 1B).

Removal of Transvenous Pacemaker Electrodes under Cardiopulmonary Bypass [PDF]

open access: yes, 1998
We report a patient in whom removal of transvenous pacemaker electrodes under cardiopulmonary bypass was successfully performed. The patient was a 75-year-old man who had undergone unsuccessful surgical treatments eight times followed by development of ...
