Sure. So yes. I mean, as I said, looking into 2021, the trajectory -- the growth trajectory is those high strong double-digit top and bottom line, Vijay. And again, I think that's going to be predicated on 2 factors, just like we spoke about it in July in the earnings call, it's going to be the continued recovery of our base business and then, obviously, our ability to ramp up COVID and COVID testing.
If you look at the businesses that were most hit by COVID, devices and core lab, so laboratory testing outside -- out of COVID, those have shown a really, really nice recovery starting in June, into July and then into the third quarter. September was actually our highest month of absolute sales in the quarter for both Medical Devices, especially in the cardiovascular area, across all areas.
We saw a little bit of a July kind of pent-up growth as the lockdown started to get reduced a little bit. We saw that growth rate in July. A lot of that was some pent-up demand. So if you look at the third quarter, I'd like to look at it -- the trajectory from August to September. And when you look at that in our cardiovascular devices, those growth rates in September were much better than the growth rates in August. And the growth rates in September were better than the third quarter overall. And then that's true for both U.S. and internationally for both devices -- for devices.
In Core Lab, we actually saw a nice growth in the month of September in the U.S., in Europe and in China also. So I like the rate of recovery that we're seeing in our base business.
If you look at Electrophysiology, that was an interesting one, where when you look at the sales, we were hurt a little bit by the capital cycle, which is why we're only at about 2% or 3%. But if you look at the consumable part of our business, so -- which probably reflect better the return of procedures. So looking at mapping catheters and therapeutic catheters, we saw a high single-digit growth rate there.
So our plan here is to continue to see that recovery. And it's not just about recovery of COVID and easing, it's also the pipeline. And we've got a very rich pipeline in our Cardiovascular area, too. And in our Core Lab business, the continued rollout of Alinity, improving our menu, expanding our menu, that's all helping us become more competitive in this recovery process.
