Clinical presentations, diagnosis, and management of arrhythmias associated with cardiac tumors.

Cardiac tumors are a rare cause of arrhythmias in clinical practice. They can cause a broad spectrum of arrhythmias, from low-grade ectopics to incessant ventricular tachycardias, including sudden cardiac arrest. Both primary and secondary cardiac tumors can produce arrhythmias, but not all tumors cause arrhythmias. Although cardiac tumors can cause arrhythmias in fetuses and older adults alike, only specific cardiac tumors are the underlying cause of arrhythmia in different age groups. This article reviews various cardiac tumors that are associated with arrhythmias, their clinical presentations, diagnostic features, and management.
