Is xanax (alprazolam) better at treating panic disorder than ativan or klonipin? & is there any possibility it causes any cardiac effects? cardiac arrest, arrythmia

Xanax (alprazolam): It is more potent during the panic attack due to its rapid onset of action, although with all those meds. There is potential for abuse, dependency & withdrawal. Any of them at doses higher than recommended daily dose, or if taken along with other meds. That adds to their effect, can lead to respiratory depression & cardiac problems. Close monitoring by a qualified physician is strongly advised.

See below: Any of these can cause cardiac arrest or arrhythmia especially if overused. Xanax (alprazolam) is shorter-acting, Ativan is a little longer-acting so it can build up more in your system. While none of these are safe for long-term use, i would say that xanax (alprazolam) is the safer of the two.
