First, we should define symmetry. Symmetry is the arrangement of body parts so they can be divided equally along an imaginary line or axis. In marine life, the two main types of symmetry are bilateral symmetry and radial symmetry, although there are some organisms that exhibit biradial symmetry (e.g., ctenophores) or asymmetry (e.g., sponges).

Procainamide (Procanbid, Pronestyl, Pronestyl [SR]) Procainamide is a class IA antiarrhythmic used for VT that is refractory to defibrillation and epinephrine. It is indicated for ventricular arrhythmias such as sustained VT. Procainamide is available only in IV form and is rarely used, because of hypotension and proarrhythmia risk.
