What is a Ca(2+) wave? Is it like an Electrical Wave?

Penelope A Boyden¹, Wen Dun¹, Bruno D Stuyvers².

Abstract

Arrhythmia subcellular mechanisms are constantly being explored. Recent knowledge has shown that travelling Ca(2+) waves in cardiac cells are critical for delayed afterdepolarisations and in some cases, early afterdepolarisations. In this review, we comment on the properties of cardiac Ca(2+) waves and abnormal Ca(2+) releases in terms of properties used to describe electrical waves; propagation, excitability and refractoriness.
