| Omega-3 fatty acids stabilize the cardiac membrane and protect
| against arrhythmias, including ventricular arrhythmias, through
| both direct electrophysiologic actions and positive effects on
| biological processes involved in atrial remodeling. However,
| omega-3 fatty acids have direct effects on the activity of
| cardiac calcium, sodium, and potassium ionic currents, which
| can alter the duration of the ventricular action potential.
| Therefore, omega-3 fatty acids may promote re-entrant
| arrhythmias, despite being anti-arrhythmic in therapeutic
| conditions. Several previous studies have evaluated the
| electrical characteristics of the ventricular wall; few studies
| have evaluated how omega-3 fatty acids influence the atria._

| Algae oil [0] which is plant based is also a source of EPA
