Please explain

What is the role of Ca2t in a cardiomyocyte's action potential? (Note: be careful not to confuse cardiomyocytes with pacemaker cells or action potentials with E-C coupling.) O Ca2+ causes a more rapid depolarization of the SA node O Ca2 causes a slower depolarization of the SA node. Ca2 entry through voltage-gated Ca2 channels causes calcium-induced calcium release. experience tetanus. Ca2 slows the rate of repolarization, increasing the latent period, and ensuring that the muscle cannot experience tetanus.

Explanation / Answer

calcium entry through voltage gated calcium causes calcium induced calcium release. After depolarization with sodium uptake L type calcium channels open and the calcium channels open up for calcium uptake. These calcium ions inside the cardiomyocytes, the calcium then activates the ryanodine receptors on sarcoplasmic reticulum to release more calcium from it. this i called calcium induced calcium release.
