I got my EMT cert (12 credits) at a community College while also taking 9 credits toward my undergrad at my regular university. It's a lot of work so make sure you can fit it into your schedule. I will be working full time as an EMT doing 911 calls soon while also working on my undergrad (we'll see how that goes), also a lot of work. The value of your experience has a lot to do with how you can talk about it in essays and interviews.
Obviously I'm biased, but I would recommend getting your EMT. I haven't started working yet, but just from the clinical shifts I did in EMT school, I know it will be valuable experience and a fulfilling job and it will prepare me, personally, for the rigors of med school and residency (because of all the work). Just be warned, that if you want to get a job, they can tend to be very competitive. In my area at least, most ED's want you to have extra certs to even be considered for an interview, and most fire departments don't hire on people who are only EMT, so you'd likely end up working your first EMT job at a private ambulance company where you're subject to union rules about seniority, meaning you likely won't get to pick your (ideal) schedule until a year or two on the job. The private company's also tend to be the ones who do the "taxi cab" work that some people talk about. Just know that as long as that sort of work doesn't make you hate your life, it is still good experience that, by adding a dash of creative writing, can be turned into something that med schools will love seeing in your essays and hearing about in interviews.
Getting your EMT also opens up more unique volunteer opportunities. i.e. Near where I live, there is summer camp for children with life threatening illness who have a volunteer staff of doctors, nurses, medics, and EMTs who make sure all the kids stay healthy during their time at camp.
I got very lucky getting the EMT job I got and it's far from typical. I got rejected from probably a dozen hospitals, and turned down a job with a private ambulance company because of the scheduling issues, and I didn't like the company very much (seemed to have unprofessional staff). If you think you'll enjoy it and be able to talk about it as valuable experience regardless of where you end up working/volunteering, then I'd say go for it.
