These include diet pills, decongestants, asthma inhalers, and some medications used to prevent arrhythmias (a serious heart rhythm problem) or treat an underactive thyroid.

A study using ex vivo rat hearts and myocyte cell culture has also identified fingolimod as a candidate drug for preventing cardiac arrhythmias resulting from ischemic/reperfusion injury.

Fingolimod prevents arrhythmias through the activation of Pak1 and its downstream effectors.

Additional objectives are to prevent life-threatening arrhythmias or conduction disturbances.

Selective inhibition of persistent sodium current by F 15845 prevents ischaemia-induced arrhythmias.

It is not entirely clear how this occurs, but it is suspected that a major factor is their ability to prevent ventricular arrhythmias.

The ability of beta-blockers to prevent ventricular arrhythmias further emphasizes why all people with heart failure should be taking them.

Patients with Brugada syndrome can prevent arrhythmias by avoiding these drugs, or use them only in controlled conditions.

The prolongation of the action potential duration and refractory period, combined with the maintenance of normal conduction velocity, prevent re-entrant arrhythmias.

The omega-3 fatty acids in fish oil can help prevent arrhythmias, decrease triglycerides (a type of fat in the blood), slow down the buildup of plaques in the arteries, and slightly lower blood pressure.
