Where to get telemetry tech training?

A nurse on this forum suggested I work as a monitor technician while in my pre-nursing studies. I thought that was an awesome idea and would love to find out from you all if you know of a good way to get some basic training in this area.

I have been a stay at home mom for many years and haven't worked in about 10 years.

I found Learn Rhythm online training which is part of the ALCS certification on the AHA's website, but it is for health professionals such as nurses. However, I can purchase it and I wonder if this would be good enough for me to apply for any positions as a telemetry technician? If not, where can I get basic online training in this area? My community college offers it but it is over $1000.

I would appreciate any help!
I think the AHA rhythm strip class is like $50. At that price, it's worth a shot. However, I think it's way more important to work as a NA if you've never done it. Your NAs can make or break you, and working as one will teach you to be a considerate co-worker.

Thanks!
