"Rapid Interpretation of EKG's" ( "The Orange Book") is a really good text for understanding the heart.

You may want to try your local Hospital or Urgency Care Facility, try to get a job as a Patient Transporter or any other entry level position; it'll give you an opportunity to get familiar with the hospital environment and equipment ( IV pumps, EKG monitors, respirators, etc...); you will also be making a lot of contacts and it looks good on your resume.
