Key result
Prototype high-resolution ECG detects R wave peaks and small potentials between P and QRS.
Why the study?
High-resolution ECG can non-invasively detect subtle low-amplitude intracardiac potentials, but the feasibility of real-time 24-bit signal acquisition and web-based processing needed validation.
A novel 24-bit high-resolution ECG platform demonstrates technological feasibility for detecting low-amplitude intracardiac potentials non-invasively.
Hypothesis-generating for non-invasive low-amplitude potential detection; larger validation studies required before clinical consideration.
Cardiovascular diseases represent the primary cause of mortality in contemporary society. However, the majority of these conditions can be effectively diagnosed at an early stage through the use of Electrocardiography (ECG). ECG with high resolution, recorded from the body’s surface, has the capability to detect subtle intracardiac potentials with low amplitude, thereby reducing the need for invasive diagnostic procedures. Enhanced resolution in ECG acquisition enables the generation of more detailed signals, which increases the potential for identifying additional features compared to conventional methods. This study introduces a platform employing a 24-bit analog-to-digital converter for real-time acquisition of ECG signals. These signals are transmitted to a web-based system for subsequent processing and analysis. The research aims to validate the technological feasibility of acquiring ECG signals at 24-bit resolution, facilitating immediate clinical interventions and providing a foundation for future investigations. A prototype device was tested by capturing patient ECG signals, which were processed using advanced filters to identify key areas of clinical relevance.

Cunha et al. (2025) studied Cardiac electrical activity monitoring (n=2). High-resolution ECG with digital processing platform was evaluated on Detection of ECG peaks and low-amplitude potentials. A prototype high-resolution ECG system successfully acquired and processed signals from two patients, enabling the non-invasive detection of R wave peaks and small potentials between the P wave and QRS complex.
