Cardiology Tests - ECG, Echo, Stress Tests

This dataset contains comprehensive cardiovascular diagnostic test results, including ECG interpretations, echocardiogram measurements, stress test findings, Holter monitor reports, and cardiac catheterization data for individual patients. It enables detailed analysis of cardiac function, arrhythmias, and vessel health, supporting both clinical decision-making and research into cardiovascular diseases.

Behind this dataset

Same schema. As many rows as you need.

These 100 rows came out of a blueprint — 22 columns with generation rules behind each one. Open it in Data Factory to retune a column, add your own, wire in foreign keys, and run it at the size you actually need.

Rules it was built with
  • Test ID unique per procedure
  • Test type: ECG, echocardiogram, stress test, Holter, cardiac cath
  • ECG: rate, rhythm, intervals (PR, QRS, QT), axis, findings
  • Echo: ejection fraction (EF), chamber dimensions, valve function
  • Stress test: protocol, duration, METS, HR/BP response, symptoms
  • Ischemic changes or arrhythmias noted
  • Nuclear imaging if pharmacologic stress test
  • Holter monitor: burden of arrhythmias, significant events
