Cerebrovascular Diseases Extra, 2011 Background: Stroke is often unexplained in younger adults, although it is often associated with a patent foramen ovale (PFO). The reason for the association is not fully explained, and mechanisms other than paradoxical embolism may be involved.

Heart Block Caused by Cardiac Metastasis From Merkel Cell Carcinoma: A Case Report
Mayo Clinic Proceedings: Innovations, Quality & Outcomes, 2019 Merkel cell carcinoma (MCC) is a rare, rapidly proliferating skin cancer that commonly metastasizes to regional lymph nodes. We present the case of a 73-year-old woman with a history of MCC and non-Hodgkin B-cell lymphoma who presented with second-degree

Pericardial Fat is Associated With Atrial Conduction: The Framingham Heart Study [PDF]
, 2014 Background: Obesity is associated with altered atrial electrophysiology and a prominent risk factor for atrial fibrillation. Body mass index, the most widely used adiposity measure, has been related to atrial electrical remodeling.

Atypical advanced interatrial blocks: Definition and electrocardiographic recognition
Journal of Electrocardiology, 2018 The diagnosis of advanced interatrial block (A-IAB) is done by surface ECG analysis when the P-wave ≥120 ms with biphasic (±) morphology in leads II, III and aVF. In this brief communication, we advance a new concept involving atypical patterns of A-IAB due to changes about the morphology or duration of the P-wave.

A review of multisite pacing to achieve cardiac resynchronization therapy [PDF]
, 2017 Non-response to cardiac resynchronization therapy remains a significant problem in up to 30% of patients. Multisite stimulation has emerged as a way of potentially overcoming non-response.
