I came across a job posting that I qualify for on a step-down cardiac unit. However, it's requiring that I have a basic dysrhythmia course as part of the qualifications. I understand that most positions require that you obtain ACLS and basic dysrhythmia courses usually within 30-60 days after hire, but this position requires that you have both upon applying. So my question is, what class do you recommend I take? Is 12 lead ECG interpretation the same as basic dysrhythmia? I'm not sure which to choose. I ask this because the only classes I'm finding are related to ECG 12 lead interpretation. I've looked at local hospitals around the LA area and I'm not finding anything. I found one class online but I'm not sure if it's legitimate? I'd really appreciate any feedback!
