- **SOC code:** 29-2031.00
- **Canonical URL:** https://singulariki.com/roles/role-29-2031-00
- **Also known as:** Cardio Tech (Cardiovascular Technician), Cardiology Technician, Cardiovascular Technologist (CVT), Registered Cardiovascular Invasive Specialist (RCIS), Cardiac Cath Lab Technologist (Cardiac Catheterization Laboratory Technologist), Cardiac Catheterization Technician, Cardiac Technician, Cardiopulmonary Technician
- **Frame:** "AI exposure" means task overlap (how codifiable the work is), not jobs lost or a forecast. Every figure below is traced to a named public dataset.

## What this work is

**Core tasks** (O*NET):
- 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.
- Compare measurements of heart wall thickness and chamber sizes to standard norms to identify abnormalities.
- Maintain a proper sterile field during surgical procedures.
- Explain testing procedures to patients to obtain cooperation and reduce anxiety.
- Observe ultrasound display screen and listen to signals to record vascular information, such as blood pressure, limb volume changes, oxygen saturation, or cerebral circulation.
- Monitor patients' blood pressure and heart rate using electrocardiogram (EKG) equipment during diagnostic or therapeutic procedures to notify the physician if something appears wrong.
- Assist physicians in the diagnosis and treatment of cardiac or peripheral vascular treatments, such as implanting pacemakers or assisting with balloon angioplasties to treat blood vessel blockages.
- Obtain and record patient identification, medical history, or test results.
- Operate diagnostic imaging equipment to produce contrast enhanced radiographs of heart and cardiovascular system.
- Assess cardiac physiology and calculate valve areas from blood flow velocity measurements.
- Monitor patients' comfort and safety during tests, alerting physicians to abnormalities or changes in patient responses.
- Observe gauges, recorder, and video screens of data analysis system during imaging of cardiovascular system.

**Emerging tasks** (O*NET):
- Perform general administrative tasks, such as answering telephones, scheduling appointments, or ordering supplies or equipment.

## AI exposure & outlook

- **AI task-overlap index:** 39th percentile (Moderate) across all occupations — composite of current-era exposure studies (ai-exposure-index-v1).
- **Overall AI exposure (Felten et al.):** 46th percentile (Moderate) — source: felten_aioe.
- **LLM task exposure, γ (OpenAI / Eloundou):** 52nd percentile (Moderate) — source: eloundou_gamma.
- **AI assistant applicability (Microsoft):** 26th percentile (Low) — source: microsoft_applicability.
- **Frey–Osborne (2013, historical computerization estimate):** 35th percentile — kept separate from current-era studies.
- **Remote-capable (Dingel–Neiman):** no — task structure, not who actually works remote.
- **Projected employment (BLS 2024–34):** 3.0% growth (About average); 3.8k annual openings; 64.7k → 66.6k jobs.
- **Pay & employment (BLS OEWS, May 2024):** median $67,260; 61,180 employed.

## How people actually use AI here

Anthropic Economic Index — measured AI conversations mapped to this occupation's tasks:

- **Automation vs augmentation:** — automation, 76% augmentation (usage-weighted).
- **Autonomy median:** 3.0 (higher = AI acts more independently).
- **Dominant collaboration mode:** learning.

**Tasks most handed to AI here:**
- Explain testing procedures to patients to obtain cooperation and reduce anxiety. _(0.8% of measured AI use; learning)_

**Example prompts (honest phrasings of the tasks above — starting points, not endorsed instructions):**
- Help me explain testing procedures to patients to obtain cooperation and reduce anxiety.
