There are four main groups of antiarrhythmic medications: class I, sodium-channel blockers; class II, beta-blockers; class III, potassium-channel blockers; class IV, calcium-channel blockers; and miscellaneous antiarrhythmics, or unclassified antiarrhythmics.

The calcium-channel blockers represent a group of organic chemical structures that share the ability to inhibit Ca2+ entry into excitable cells. In coronary and peripheral arterial smooth muscle and the heart, inhibition of Ca2+ entry blunts the ability of Ca2+ to serve as an intracellular messenger. Thus, calcium-channel blockers are smooth ...In addition, although traditional meta-analysis indicated that calcium channel blockers use was associated with increased risk of depression, it is worth noting that this conclusion to a large extent was dependent on the cohort study by Cao et al.
