Management of Cardiac Rhythm Disorders in Cardio-oncology.

ABSTRACT: Arrhythmias and cancer are two pathological conditions that often coexist due to a patient's pre-existing comorbidities, or toxicity linked to anti-neoplastic drugs, and both are often characterised by poor prognosis. Cardio-oncology is a new interdisciplinary field that focuses on the cardiovascular health of cancer patients, especially those undergoing cancer treatment. Furthermore, cardiotoxicity can cause arrhythmias through primary and secondary mechanisms. Chemotherapy drugs have been shown to directly affect molecular pathways associated with arrhythmia development, as well as indirectly through mechanisms involving ischaemia or inflammatory injury to the heart. Understanding how to prevent and to treat these electrophysiological issues in cancer is an important challenge for cardio-oncologists. This review explores the intersection between cardio-oncology and electrophysiology, the various cardiac cell types implicated in the development of arrhythmias during cancer, the interplay between arrhythmias and cancer pathogenesis, and the need for the implantation of electronic devices along with their associated risks.
