Two recent research studies have found differences between the distribution of potassium-ion-channel variants in the mouse heart and in the human heart. In the mouse, the ion channels in the atria are different from those in the ventricles. In people there is no such chamber specificity. The difference is crucially important for the development of safe and effective cardiovascular drugs.

Human Response To Electric Shock The effect of electrical shock varies widely from person to person. Figure 21.1 shows the general reactions that occur as a result of 60 Hz ac current flow through the New research has showed substantial differences in the way human heart cells respond to e-cigarette smoke and conventional cigarette smoke. The heart beats in response an electrical impulse in all the myocardial (heart muscle) fibers that initiates a chain reaction starting with calcium interacting with some plex protein molecules in each of the cells.
