Cardiovascular monitoring devices and cardiac marker tests
Cardiovascular monitoring devices record how the heart and circulation are working. This short explainer describes the category and how it complements cardiac marker rapid tests. First Diagnostic™ Corporation does not supply monitoring devices.

What cardiovascular monitoring devices are
Cardiovascular monitoring devices measure physiological signals from the heart and circulation, either at one moment or over hours and days. The main groups are:
- Blood pressure monitors: cuff-based devices for clinic use and ambulatory monitors worn over a longer period.
- ECG devices: resting electrocardiographs, wearable recorders and adhesive ECG patches that record heart rhythm.
- Pulse oximeters: sensors that estimate oxygen saturation and pulse rate.
- Implanted devices with remote follow-up: pacemakers and implantable monitors that transmit rhythm data to the care team.
How monitoring complements cardiac marker rapid tests
Monitoring devices record function: pressure, rhythm and electrical activity. Cardiac marker tests look for proteins in a blood specimen, such as troponin I, CK-MB and myoglobin. The two kinds of information are read together by the clinician, along with the history and examination.
In the assessment of chest pain, the ECG and laboratory troponin testing follow the local protocol. A qualitative lateral flow test for a cardiac marker supports that assessment and never replaces it. The cardiac marker rapid tests page lists the tests in our range, including the ATFirst™ cardiac troponin I rapid test.
Results from a rapid test are an aid to diagnosis and must be interpreted by a clinician with other clinical and laboratory findings.
Not supplied by First Diagnostic today
First Diagnostic does not supply cardiovascular monitoring devices today. Its range consists of lateral flow rapid tests for professional in vitro diagnostic use, listed in the rapid tests catalog.

Frequently asked questions
Does First Diagnostic sell blood pressure monitors or ECG devices?
No. First Diagnostic does not supply cardiovascular monitoring devices today. The current range is lateral flow rapid tests for professional use.
Can a cardiac marker rapid test replace an ECG?
No. They measure different things. A rapid qualitative test supports, and never replaces, the ECG and laboratory troponin testing required by the local chest-pain protocol.
Are monitoring devices and rapid tests regulated the same way?
No. Monitoring devices are medical devices, while rapid tests are in vitro diagnostic devices. See what is a medical device.
