Cardiology trials run on precise, repeated measurements. Capture’s ECG and vitals templates come with QTc, QTcF, MAP and pulse pressure as calculated fields, so a value is computed the same way every time and flagged automatically when it is out of range.

ECG and vitals
The template library includes ECG and vital signs forms you can use as they are or hand to the AI to adjust for your specific protocol. Upload a source sheet or describe the change, and review the draft before anything is saved.

Calculated fields
Map a calculated field to the blood pressure or heart rate and QT interval questions already on the form, and Capture fills in the derived value read-only during entry. No site-by-site variation in which formula was used.
Haematology

| Haemoglobin | HGB | g/dL | 13.0-17.0 | Male 18-65 y |

Data quality
Attach range rules to any measurement. When a site enters a QTc, blood pressure or heart rate value that breaks your rule, Capture raises an auto-query straight away, with your own message template filled in with the value and the limit.

Before you switch
Calculated fields and edit checks are included at every tier, including the free sandbox.
21 CFR Part 11-aligned controls throughout; documentation available on Enterprise to support your own validation.
AI drafts your ECG and vitals forms from a protocol or existing sheet; most teams build the same day.
Bring an existing study’s forms across as a starting template.
Email support, typically under 24 hours, plus documentation for your own assessment on Enterprise.
Free sandbox with every feature. No credit card, no sales call.
Bazett and Fridericia, both available as calculated fields mapped to the QT interval and heart rate questions on your form.
Yes. Both can be set up as calculated fields from systolic and diastolic blood pressure, filled in read-only during entry.
Yes, alongside vitals, demographics, physical exam, medical history, adverse events and laboratory templates. The AI can adapt any of them to your specific protocol.
If you have set a range rule on that field, Capture raises an auto-query automatically, using your own message template with the entered value and the limit filled in.
Yes. CSV and Excel exports include calculated fields alongside their source values, with an automatic data dictionary describing each one.
Nothing to start. The free sandbox has no credit card and no time limit. You pay only once you go live with real participant data.
