@jaki101 Do you live in the US? QUOTE: Federal law, primarily through the 21st Century Cures Act and HIPAA, requires healthcare providers to give patients immediate, free, and electronic access to their medical records and health information. The "Open Notes" rule mandates that doctors provide, via patient portals or apps, access to notes, lab results, and reports without unreasonable delays. Online Availability: Most modern medical facilities, clinics, and hospitals now use EMR systems that allow patients to view their health information online, often via secure, downloadable apps.
Did you ask them and what did they tell you? Make them give records to you! Test results AND DOCTOR NOTES. I would not let them get away with anything. It is their job.

@jaki101 Also always check to see if your doctors are Board certified .. here is a place to do it https://www.certificationmatters.org/boards/

@jaki101 so your current cardiologist does not have a portal with your records online. All the more reason to seek out a new cardiologist. This one is not being transparent or staying up to date with technology. Since your records are NOT online, start the process of having your records printed out and given to you. There may be a small charge for this, but it will be worth it. Bring them to your new cardiologist.
