## Cardisiography in numbers

the manufacturer's worldwide data

- **500,000+** Patients have been screened with Cardisiography (CSG) over the past 5 years. [For physicians](https://www.cardisio.com.tr/en/for-clinicians)
- **1,200+** Medical practices and clinics trust Cardisiography worldwide. [About us](https://www.cardisio.com.tr/en/about)
- **130,000+** Previously undetected heart conditions have been identified by physicians in examinations performed with Cardisiography. [Cardisiography](https://www.cardisio.com.tr/en/cardisiography)
- **13** Clinical studies with patient data are listed one by one on our evidence page. Background literature and a simulation paper without patients are not counted. [Clinical evidence](https://www.cardisio.com.tr/en/clinical-evidence)

## The report a physician receives

- The test gives the physician an easy-to-interpret report. Six sample pages follow.
- The report carries AI-powered indices: perfusion, structural heart disease, and arrhythmia index.

All six sample pages

- Vectorcardiography loops in three planes, with the VCG results table, scatter analysis and pretest risk bar beside them.
- The absolute cardiogram as a three-dimensional surface and heat map, with the analysis of the R and T peaks below.
- Rhythm analysis: a Poincaré plot, a histogram and rhythm strips, next to ECG results with their references.
- The ECG recording of chest leads V1 to V6 on millimetre grid paper.
- The recording of the additional leads, V7 to V9 and V3R to V6R, on millimetre grid paper.
- Decision trees for perfusion, structure and rhythm, ending in the P, S and A factor bars.

## The test in three steps

1. **Recording**: In the four-minute recording, five electrodes are attached to the body, similar to an ECG.
2. **AI analysis**: The recorded parameters are immediately transmitted to the Cardisio server and processed into a report using an AI algorithm.
3. **Conversation with the physician**: A medical professional discusses the results with the patient.

## Decision support in disease detection

The manufacturer states that, thanks to the simple and accurate decision support that Cardisiography offers, physicians can initiate appropriate treatment steps early and make informed decisions on further diagnostics and referrals. Cardisiography does not diagnose; it provides decision support to the physician in the diagnostic process. The physician makes the diagnosis.

The manufacturer's diagram: a curve running from green to red over the axes progression of the disease and stages of change. The stages are, in order, changes at the cellular level, repolarization, depolarization, tissue damage and irreversible damage to heart muscle cells. In the manufacturer's depiction, Cardisiography is marked on the early part of the curve and conventional ECG further along.

## Confirmed by evidence

These four results come from a prospective cohort study by NHS and SBRI Healthcare on community-based heart testing in primary care. It took place in three settings (general practice, a pharmacy and a community health centre) and included 628 asymptomatic, elevated-risk adults aged 18 or over. Every result of the study is on the [clinical evidence page](https://www.cardisio.com.tr/en/clinical-evidence).

- Sensitivity: 73.8%
- Specificity: 94.4%
- Positive Predictive Value (PPV): 80%
- Negative Predictive Value (NPV): 90.4%

## Advantages at a glance

- **Non-invasive**: The test is non-invasive and performed while the patient is in a resting state; no stress test is needed.
- **Four minutes**: Unlike conventional ECGs, which record for only a few seconds, Cardisiography analyzes the heart over four minutes.
- **Five electrodes**: The test is performed much like an ECG, with five electrodes, at rest.
- **In 1 minute**: Results within 1 minute of the recording.
- **A readable report**: The report is delivered as a PDF and laid out so the physician can interpret it easily.
