Arrhythmia Challenges in Cardio-Oncology: High-Risk Therapies, Management, and Anticoagulation.

Cardiovascular disease and cancer are the leading cause of mortality in the United States. In 2021, there were 695,547 and 605,213 deaths due to heart disease and cancer, respectively. With novel oncologic and cardiac therapies, survival has improved leading to increased life-expectancy albeit with chronic illness burden. Arrhythmia management in patients with cancer, whether active or in remission, can be quite challenging. In this review, we will discuss high-risk oncological therapies, prevention, and management of Atrial fibrillation, Ventricular Arrhythmias, and Bradyarrhythmias.
