Is There a Relationship Between Calcium and Heart Failure?

There's probably a relationship between te the levels of these, a different electrolytes, and the propensity for ventricular rytmus antony. And so if re polarization is part of the mechanism and suddenly you have no potassium, is the, excuse me, you have no calcium present? Is that the idea that if you didn't also have hypo chalcenia, or profound hypochalcena, you wouldn't also get hypo calmic ventricular rena?"
