Cardiovascular nursing practice includes accountability for the clinical and organizational processes to ensure positive outcomes for patients having cardiac dysrhythmias. For patients with supraventricular dysrhythmias, nurses have studied patient outcomes related to mortality, morbidity, quality of life, psychological and physical functioning, and symptoms. Nurses have also explored these same outcomes associated with the management of supraventricular dysrhythmias. In addition, nurses have contributed to understanding organizational outcomes such as healthcare utilization and costs associated with these patients. For patients with atrial fibrillation after cardiac surgery, nurses have studied patient and organizational outcomes related to mortality, morbidity, symptoms, psychological and physical functioning, and economic outcomes. This research has included numerous interdisciplinary studies, and most of it has been descriptive or observational in design. Areas for future nursing outcomes research, including more interventional studies, are discussed.
