Patient-Specific Heart Model Towards Atrial Fibrillation [PDF]

ICCPS 2021: Proceedings of the ACM/IEEE 12th International Conference on Cyber-Physical Systems, 2022
Atrial fibrillation is a heart rhythm disorder that affects tens of millions people worldwide. The most effective treatment is catheter ablation. This involves irreversible heating of abnormal cardiac tissue facilitated by electroanatomical mapping.

Reversible third-degree atrioventricular block in a Poodle-Toy with degenerative mitral valve disease and pyometra

Brazilian Journal of Veterinary Medicine, 2021
Third degree atrioventricular block is a severe arrhythmia, being the most common   indication for artificial cardiac pacing in dogs. Spontaneous reversion to normal sinus rhythm is very rare or exceptional.

Statistical model for describing heart rate variability in normal rhythm and atrial fibrillation [PDF]

, 2022
Heart rate variability (HRV) indices describe properties of interbeat intervals in electrocardiogram (ECG). Usually HRV is measured exclusively in normal sinus rhythm (NSR) excluding any form of paroxysmal rhythm. Atrial fibrillation (AF) is the most widespread cardiac arrhythmia in human population.

Left superior pulmonary vein ectopic rhythm mimicking normal sinus rhythm [PDF]

Europace, 2014
A 45-year-old man underwent pulmonary vein (PV) isolation for paroxysmal atrial fibrillation. Two alternating regular rhythms were recorded at the left superior PV (LSPV— Panel A ). The dominant rhythm had a cycle length (CL) of 672 ms, with an initial near-field …

Clinical implications of left atrial changes after optimization of medical therapy in patients with heart failure

European Journal of Heart Failure, Volume 24, Issue 11, Page 2131-2139, November 2022., 2022
Among patients with new‐onset or worsening heart failure (HF) undergoing optimization of HF medical therapy, dose up‐titration of angiotensin‐converting enzyme inhibitor/angiotensin receptor blocker (ACEi/ARB) therapy was associated with lower likelihood of left atrial adverse remodelling (LAAR).

Atrial amyloidosis: mechanisms and clinical manifestations

European Journal of Heart Failure, Volume 24, Issue 11, Page 2019-2028, November 2022., 2022
Atrial amyloidosis: pathophysiology and clinical manifestations. Atrial amyloidosis can manifest as part of a systemic disorder (as in amyloid light‐chain [AL] or transthyretin [ATTR] amyloidosis), or be isolated (in the form due to atrial natriuretic type [ANP] accumulation); this last form is often associated with permanent or persistent atrial ...
