HRM Dual Heart rate stuck at 72

I have the HRM Dual. I just bought it two weeks ago. I've gone on about 9 runs with it. During my last run, it worked perfectly for about 45 minutes and then my heart rate descended to 72. It has not moved since. It has been several days and it is very clean. It has no problem hooking up to my phone via bluetooth and connects just fine as soon as I strap up. However, the heart rate is stuck at 72 and doesn't move. Any ideas?

    Anybody knows is if the last production batch has a more reliable revision, or it's just the same? It worked very very well since yesterday, the strap looks perfect even though I've done runs for about 700km, I don't really know what's could be, but probably something related to the overall quality of the product.
