Can agents do the work of cardiovascular technologists and technicians?
We read the evidence at the level of the job family, Healthcare:
- Task levelPartialOne benchmark, from early 2025. On Stanford's MedAgentBench, where agents do clinical tasks in a simulated electronic health record, the best recorded model completes 69.7% of tasks (Claude 3.5 Sonnet v2). It has no maintained leaderboard, so newer models are not measured. No benchmark in our collection tests work with patients.
- Project levelPartialOnly adjacent evidence. GDPval includes nurses among its 44 occupations. OpenAI reports that GPT-5.5's deliverables won or tied against professionals' work in 84.9% of comparisons across all occupations. No benchmark in our collection tests clinical work over days, such as managing a patient's care.

Typical tasks
From O*NET 31.0. Core tasks first. Few of these tasks have a benchmark today.
- Conduct electrocardiogram (EKG), phonocardiogram, echocardiogram, stress testing, or other cardiovascular tests to record patients' cardiac activity, using specialized electronic test equipment, recording devices, or laboratory instruments.
- Explain testing procedures to patients to obtain cooperation and reduce anxiety.
- Monitor patients' blood pressure and heart rate using electrocardiogram (EKG) equipment during diagnostic or therapeutic procedures to notify the physician if something appears wrong.
- Obtain and record patient identification, medical history, or test results.
- Monitor patients' comfort and safety during tests, alerting physicians to abnormalities or changes in patient responses.
- Prepare and position patients for testing.
- Attach electrodes to the patients' chests, arms, and legs, connect electrodes to leads from the electrocardiogram (EKG) machine, and operate the EKG machine to obtain a reading.
- Adjust equipment and controls according to physicians' orders or established protocol.
- Check, test, and maintain cardiology equipment, making minor repairs when necessary, to ensure proper operation.
- Supervise or train other cardiology technologists or students.
- Compare measurements of heart wall thickness and chamber sizes to standard norms to identify abnormalities.
- Maintain a proper sterile field during surgical procedures.
