Spontaneous Non-Sustained Ventricular Tachycardia and Premature Ventricular Contractions and Their Prognostic Relevance in Patients with Cancer in Routine Care

We found that cancer patients with primarily advanced disease develop an increased vulnerability of the heart leading to ventricular arrhythmias, which are associated with increased mortality.

Translation and Psychometric Testing of the Norwegian Version of the “Patients’ Perspectives of Surgical Safety Questionnaire”

The first Norwegian version of the PPSS measuring surgical patients' perception shows promising psychometric properties regarding structural validity and internal consistency.
