Principal component analysis of atrial fibrillation: Inclusion of posterior ECG leads does not improve correlation with left atrial activity [PDF]

, 2015
Background Lead V? is routinely analysed due to its large amplitude AF waveform. V? correlates strongly with right atrial activity but only moderately with left atrial activity. Posterior lead V? correlates strongest with left atrial activity.

Intermediate-Term Risk of Stroke Following Cardiac Procedures in a Nationally Representative Data Set. [PDF]

, 2017
BACKGROUND: Studies on stroke risk following cardiac procedures addressed only perioperative and long-term risk following limited higher-risk procedures, were poorly generalizable, and often failed to stratify by stroke type. We calculated stroke risk in

1% Aspiration, 99% Perspiration

JACC: Case Reports, 2020
A 71-year-old man with chronic atrial fibrillation underwent insertion of a left atrial appendage occlusion device. Before release, a large thrombus was noted within the left atrium, attached to the left atrial appendage occluder delivery system.

Cardioverting acute atrial fibrillation and the risk of thromboembolism: not all patients are created equal [PDF]

, 2017
Current guidelines support the well-established clinical practice that patients who present with atrial fibrillation (AF) of less than 48 hours duration should be considered for cardioversion, even in the absence of pre-existing anticoagulation. However,

Investigating the relationship between the shape of the left atrial appendage and the incidence of atrial fibrillation in patients diagnosed with atrial fibrillation [PDF]

Journal of Cardio-Thoracic Medicine
Introduction: Appendage is the growth of the left atrium, which is different in terms of shape and size. This research aimed to investigate the relationship between the shape of the left atrium appendage and atrial fibrillation incidence.Methods: In a ...
