Abstract

To assess the effectiveness of the management of patients with cardiac electronic implantable devices (CEIDS) receiving radiotherapy. In 2005, a formal communication process was established between Radiation Oncology and Cardiac Electrophysiology (EP) for the management of patients with permanent, implantable cardiac devices receiving radiotherapy. The process requires a pre-treatment consult with EP. This information is provided to a medical physicist, who works with the primary radiation oncologist and dosimetrist. Based on the estimated dose to the device, EP and Radiation Oncology will determine the appropriate oversight required for treatment. To assess the effectiveness of this program, a retrospective analysis of patients with implantable cardiac devices receiving radiotherapy between the years 2005 and 2011 was performed. Sixty-nine patients with CEIDs (19 implantable cardioverter defibrillators (ICDs) and 50 pacemakers) were treated in Radiation Oncology between 2005 and 2011. Patients were treated to a variety of sites, including 21 patients treated to multiple sites. Doses were estimated prior to radiotherapy, and in vivo measurements were obtained for patients near or exceeding our institutional device tolerance (IC...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Cardiac Electrophysiology

Cardiac electrophysiology is the study of electrical activities of the heart and includes the assessment, diagnosis, and treatment of cardiac events. Find the latest research on cardiac electrophysiology here.
