[Screening-diagnostics of the myocardium during test-loading on bicycle ergometer]

Area of Science:

• Cardiology
• Medical Technology
• Physiology

Background:

• Early detection of myocardial electrophysiological deviations is crucial for preventing cardiovascular disease.
• Standard functional tests like bicycle ergometry are vital for assessing cardiac health.
• Existing methods may have limitations in identifying subtle or transient electrophysiological changes.

Purpose of the Study:

• To assess the diagnostic and prognostic potential of KardioVizor-06 (KV) for early detection of myocardial electrophysiological parameter deviations.
• To evaluate the performance of KV during a standard functional test (bicycle ergometer).
• To compare KV data with standard electrocardiogram (ECG) and blood pressure (BP) measurements.

Main Methods:

• Utilized the KardioVizor-06 (KV) device for data acquisition during baseline, test, and recovery phases.
• Conducted a standard functional test using a bicycle ergometer with 10 healthy subjects.
• Compared KV data with standard 12-lead ECG and BP monitoring.
• Analyzed automated ECG data for noise immunity and dispersing changes.

Main Results:

• KardioVizor-06 (KV) demonstrated data agreement with standard ECG and BP methods in 90% of cases.
• KV slightly underestimated test tolerance in 10% of participants.
• Analysis of ECG data from KV revealed incipient myocardial deviations not always apparent with standard methods.
• The technology provides unique information, identifying transient functional disorders.

Conclusions:

• KardioVizor-06 (KV) shows promise for the early detection of myocardial electrophysiological deviations.
• The device offers unique diagnostic information, particularly for transient functional disorders.
• High noise immunity allows for direct application during functional loading tests, enhancing clinical utility.
