Figure 2: Myocardial (Ca++)i in rat papillary muscle at rest. In those rats which received high dose vit. D3, (Ca++)i was increased over 160 times. This rather dramatic rise in (Ca++)i could be largely prevented by s.c. administration of diltiazem and verapamil.

Figure 3: Typical membrane potential (Vm), Ca++-electrode potential (VCaE) and differential potential (Vdiff) as well as resting tension in control conditions (left hand panel) and in vit. D3-intoxicated rats (right hand panel). Recordings from two individual experiments.

Figure 4: Resting tension increases more than twofold in papillary muscels of vit. D3-intoxicated rats. The administration of diltiazem or verapamil attenuates this increase in resting tension.
