### Description

The first measurement of isospin fluctuations in the kaon sector is reported in Pb-Pb collisions at $\sqrt{s_{NN}}=$ 2.76 TeV, recorded with the ALICE detector. A robust statistical observable $\nu_{dyn}$ was used to extract the novel isospin fluctuations from the distributions of neutral and charged kaons as a function of collision centrality. The results show a significant variation in the behaviour of $\nu_{dyn}$ in data when compared to existing Monte-Carlo models such as HIJING and AMPT. The details of the analysis and systematic studies in the extraction of $\nu_{dyn}$ and its centrality dependence in both data and Monte-Carlo models are reported.
