Excessive Premature Atrial Complexes and the Risk of Recurrent Stroke or Death in an Ischemic Stroke Population.

Background: Our aim was to investigate the association of premature atrial complexes and the risk of recurrent stroke or death in patients with ischemic stroke in sinus rhythm.

Methods: In a prospective cohort study, we used 24-hour Holter recordings to evaluate premature atrial complexes in patients consecutively admitted with ischemic strokes. Excessive premature atrial complexes were defined as >14 premature atrial complexes per hour and 3 or more runs of premature atrial complexes per 24 hours.

Prevalence and Prognostic Significance of Runs of Premature Atrial Complexes in Ischemic Stroke Patients.

Background And Purpose: Runs of premature atrial complexes (PACs) are common in stroke patients and perceived to be clinically insignificant, but their prognostic significance is unclear. This study investigated the association between runs of PACs in ischemic stroke patients and the risk of recurrent ischemic strokes/transient ischemic attacks (TIAs) or death.

Methods: The study included consecutive patients admitted with an ischemic stroke from August 2008 to April 2011.

[Pelvic vein thrombosis with elevated D-dimer level and normal ultrasound scan of the femoral vein].

A 17-year-old female presented with an isolated pelvic vein thrombosis (PVT) which was not visualised at the first compression ultrasound scan of the femoral vein. Isolated PVT should be suspected when the patient demonstrates the possible symptoms of a deep vein thrombosis with unilateral leg swelling extending to the groin and a negative compression ultrasound scan of the femoral vein. Supplemental ultrasound scan with Doppler flow, computed tomography or magnetic resonance venography are alternative diagnostic modalities if PVT is suspected.

Twins with implanted pacemakers: Is there an increased mortality risk for the co-twin? A follow-up study based on the Danish Twin Registry and the Danish Pacemaker Register.

Background: The main indications for implanting a cardiac pacemaker are either acquired atrio-ventricular block (AVB) or sick sinus syndrome (SSS). In general, the exact aetiology of these conditions is unknown. Genetic factors may play a role.
