In brief: How they work.

Calcium channel blockers (ccb) affect calcium channels in the heart muscle cells.
Beta blockers (bb) affect beta receptors in the conduction pathways of the heart. Each act to decrease heart rate and can also decrease blood pressure. Sometimes with ccb, the heart experiences an increase in heart rate when blood pressure decreases. There are different brands and kinds of both medications.

In brief: Different receptor

They work on different receptors.
The antiarrhythmic propertiesbeta & ccbs are related to their ability to decrease the firing rate of aberrant pacemaker sites, and ability to decrease conduction velocity and prolong repolarization, especially at the atrioventricular node. This latter action at the atrioventricular node helps to block reentry mechanisms. Bbs decrese sympathetic drive also.
