Features
ECG tells you the rhythm. PCG tells you the reality.
While electrocardiograms (ECG) have been the standard for heart monitoring for decades, they only tell part of the story. ECGs measure the electrical activity of the heart, but they cannot directly assess the mechanical function—how well the heart is actually pumping blood.
This is where phonocardiograms (PCG) come in. PCG captures the sounds produced by the heart as it beats, providing direct insight into the mechanical aspects of cardiac function that ECG simply cannot detect.
PCG Advantages
- •Captures mechanical heart function (valve closures, murmurs, blood flow sounds)
- •Provides direct insight into valve disorders (stenosis, regurgitation, prosthetic valve issues)
- •Detects murmurs, gallops (S3/S4), rubs, and snaps—critical signs of early disease
- •Enables precise timing measurements of cardiac cycles
ECG Limitations
- •Only shows electrical activity, not mechanical function
- •Cannot detect valve disorders directly
- •Misses critical sounds that indicate early disease
- •Limited in assessing haemodynamic stress and diastolic function
Precise Timing Metrics from PCG
PCG provides critical timing measurements that offer deep insights into cardiac function:
S1/S2 Durations
The first (S1) and second (S2) heart sounds correspond to the closure of the atrioventricular valves and semilunar valves, respectively. Changes in their duration can indicate valve problems or altered haemodynamics.
Systole/Diastole Lengths
The time between S1 and S2 represents systole (heart contraction), while the time between S2 and the next S1 represents diastole (heart relaxation). Abnormal ratios can indicate heart failure or other cardiac conditions.
These precise timing metrics are key for detecting heart failure, diastolic dysfunction, and haemodynamic stress—information that ECG alone cannot provide. By analysing these metrics with advanced AI algorithms, BeatAware can identify subtle changes that may indicate developing cardiac issues before they become serious problems.
The combination of PCG and ECG provides a complete picture of heart function, integrating both electrical and mechanical data for a comprehensive assessment of cardiovascular health.
AI-Enhanced PCG Analysis
BeatAware uses advanced artificial intelligence to analyse PCG signals, extracting meaningful patterns that might be missed by human ears or traditional analysis methods. Our algorithms can identify subtle abnormalities in heart sounds that can indicate developing cardiac issues.
By combining AI with PCG technology, we enable early detection of heart problems before they would show up on an ECG or echocardiogram, potentially allowing for earlier intervention and better health outcomes.
Cardiorespiratory Health
Cardiorespiratory health refers to the ability of the circulatory and respiratory systems to supply oxygen to the body during sustained physical activity. These systems work together to ensure that your muscles receive the oxygen they need to function properly.
Research has consistently shown that cardiorespiratory fitness is a powerful predictor of overall health and longevity. Poor cardiorespiratory health is associated with increased risk of cardiovascular disease, stroke, diabetes, and other chronic conditions.
Research Validation
BeatAware's technology has been validated through rigorous scientific research and clinical studies. Our approach has been shown to provide accurate assessments of cardiorespiratory health that correlate strongly with traditional medical measures.
