Prolonged PR interval, first-degree heart block and adverse cardiovascular outcomes: a systematic review and meta-analysis [PDF]

, 2016
Objective: First-degree atrioventricular block is frequently encountered in clinical practice and is generally considered a benign process. However, there is emerging evidence that prolonged PR interval may be associated with adverse outcomes. This study

ABC of Atrial Fibrillation: CARDIOVERSION OF ATRIAL FIBRILLATION [PDF]

BMJ, 1996
Summary Cardioversion to sinus rhythm should be considered for all suitable patients in atrial fibrillation In the short term both pharmacological and electrical cardioversion restore sinus rhythm Prophylactic treatment with antiarrhythmic drugs is advisable after cardioversion in high risk patients in view of the high relapse rate Anticoagulants ...

Differences in prognosis and underuse of adjuvant chemotherapy between elderly and non‐elderly patients in stage III colorectal cancer

Annals of Gastroenterological Surgery, Volume 7, Issue 1, Page 91-101, January 2023., 2023
This study analyzed data from consecutive patients with stage III colorectal cancer following curative resection and examined the reason for not introducing adjuvant chemotherapy (AC) and the differences in prognosis between completed and incomplete AC in elderly and non‐elderly patients.

Atrial Fibrillation Detection Using RR-Intervals for Application in Photoplethysmographs [PDF]

arXiv, 2023
Atrial Fibrillation is a common form of irregular heart rhythm that can be very dangerous. Our primary goal is to analyze Atrial Fibrillation data within ECGs to develop a model based only on RR-Intervals, or the length between heart-beats, to create a real time classification model for Atrial Fibrillation to be implemented in common heart-rate ...

Effect of statins on atrial fibrillation: collaborative meta-analysis of published and unpublished evidence from randomised controlled trials [PDF]

, 2011
Objective To examine whether statins can reduce the risk of atrial fibrillation. Design Meta-analysis of published and unpublished results from larger scale statin trials, with comparison of the findings against the published results from smaller ...

Ventricular fibrillation

The American Journal of Cardiology, 1971
Ventricular fibrillation is the most common mechanism of sudden unexpected cardiac death in persons with asymptomatic or symptomatic coronary artery disease. The electrophysiologic mechanisms reviewed in this article include: automaticity of pacemaker fibers, transformation of nonpacemaker into pacemaker fibers, "injury" currents and reentry.

Prediction of need for bowel resection in acute superior mesenteric artery occlusion: A retrospective study of 48 Japanese patients

Annals of Gastroenterological Surgery, Volume 7, Issue 1, Page 175-181, January 2023., 2023
In a study of 48 patients with acute superior mesenteric artery occlusion, a logistic regression model using time from onset to diagnosis and the occlusion site of superior mesenteric artery showed 78.6% sensitivity in ruling out cases requiring bowel resection.

An equilibrium double-twist model for the radial structure of collagen fibrils [PDF]

, 2014
Mammalian tissues contain networks and ordered arrays of collagen fibrils originating from the periodic self-assembly of helical 300 nm long tropocollagen complexes. The fibril radius is typically between 25 to 250 nm, and tropocollagen at the surface appears to exhibit a characteristic twist-angle with respect to the fibril axis.
