Ondansetron-induced atrial fibrillation?

Drug-induced dysrhythmias are frequently encountered with several drugs that are routinely used in the practice of medicine. However, it is difficult to predict in which group of patients the rhythm disturbances can happen. The clinician should try to identify the cause of the new onset rhythm disturbance (electrolyte imbalance, ongoing cardiac insult, hypoxia, hemodynamic disturbance, cerebrovascular event, etc.). Once a drug is suspected, it should be documented on medical case record and everyone involved in the patients care should be informed.
