Final answer:
Halothane is the inhaled anesthetic associated with cardiac dysrhythmias. It has been replaced by less flammable and safer alternatives like desflurane, isoflurane, and sevoflurane which have fewer side effects.
Step-by-step explanation:
The inhaled anesthetic associated with cardiac dysrhythmias is halothane. This fluorine-containing compound has been used as an inhalation anesthetic, but it has been associated with various safety concerns, one of which includes the risk of cardiac dysrhythmias.
Desflurane, isoflurane, and sevoflurane are also fluorine-containing inhalant anesthetics, which are less flammable than diethyl ether, and are the most widely used today. These modern anesthetics are used primarily because they have fewer undesirable side effects and do not pose the same level of risk as halothane, especially concerning cardiac dysrhythmias.
