What is a Ca2+ wave? Is it like an Electrical Wave?

Abstract

Arrhythmia subcellular mechanisms are constantly being explored. Recent knowledge has shown that travelling Ca2+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 Ca2+waves and abnormal Ca2+releases in terms of properties used to describe electrical waves; propagation, excitability and refractoriness.
