Deep Explanation of Sensors, Algorithms, Workflow & Product Videos

Discover the advanced technology behind Pouya-Heart, combining intelligent signal processing with decades of pediatric cardiology research.

Sensors

Built on Reliable Digital Stethoscope Technology

Pouya-Heart works with commercial digital stethoscopes (such as Thinklabs™), which provide high-quality acoustic recordings suitable for advanced signal analysis.

The specific model is not critical, as long as it captures clear digital heart sound signals.

Digital stethoscopes have been shown in multiple studies to:

  • Detect acoustic features below human hearing thresholds
  • Provide more consistent and sensitive auscultation than traditional devices
  • Support better detection of subtle murmurs
  • Create reproducible recordings essential for algorithmic evaluation

The Innovation of Pouya-Heart

While the digital stethoscope serves as the recording tool, the innovation of Pouya-Heart lies in what happens next: the extraction, analysis, and interpretation of cardiac sound patterns to support early detection of CHD and CCHD.

Algorithms

25 Years of Pediatric Cardiac Signal Expertise

Pouya-Heart's core innovation lies in its advanced signal-processing algorithms, developed through more than two decades of pediatric cardiology research.

What the Algorithms Do

While the digital stethoscope captures the sound, Pouya-Heart's algorithms:

  • Isolate cardiac components from background noise
  • Analyze acoustic patterns linked to congenital heart defects
  • Distinguish pathological murmurs from innocent (physiological) murmurs
  • Evaluate timing, frequency, intensity, and spectral characteristics
  • Produce an easy-to-interpret screening result within 2 minutes

This is the technical core of Pouya-Heart.

Key Capabilities

Pouya-Heart algorithms enable reliable and objective cardiac screening across hospitals, clinics, and outreach settings by:

  • Detect subtle murmurs often missed during routine examinations
  • Recognize acoustic markers associated with CHD and CCHD
  • Correctly classify innocent murmurs as normal, reducing unnecessary referrals
  • Deliver objective, reproducible assessments independent of operator skill

How the System Interprets the Heart Sound

1

Pre-Processing

The system enhances the recording by reducing noise and optimizing neonatal acoustics.

2

Feature Extraction

It examines the sound's spectral, temporal, and intensity patterns, identifying murmur-related signatures.

3

Pattern Analysis

Extracted features are compared with patterns from normal developmental heart sounds, innocent murmurs, pathological murmurs, and known CHD/CCHD acoustic profiles.

4

Decision Model

A validated decision-support model provides a screening outcome, not a diagnosis. It helps clinicians decide when referral to a pediatric cardiologist is appropriate.

Clinically Proven Performance

The algorithms have been refined using:

  • Over 10,000 pediatric recordings
  • Multi-center trials in Iran and India
  • Real-world neonatal and pediatric workflows

Studies demonstrate high sensitivity and specificity across age groups.

Why This Approach Works

Heart-sound analysis offers unique advantages:

  • Detects cardiac anomalies missed by pulse oximetry
  • Works in settings with limited access to imaging
  • Requires no radiation, blood tests, or invasive procedures
  • Supports early and timely referral

Pouya-Heart brings modern digital analysis to one of medicine's oldest tools: auscultation.

Workflow

Built for Real Clinical Practice

Pouya-Heart is designed to integrate seamlessly into everyday pediatric and neonatal care, requiring minimal training and no changes to existing routines.

A Simple 3-Step Screening Process

1

Record

A nurse, midwife, or physician places a digital stethoscope on the child's chest and records the heart sound for a few seconds.

2

Analyze

Pouya-Heart automatically processes the recording, analyzing heart-sound patterns using validated algorithms.

3

Result

Within 2 minutes, the system provides a clear screening outcome to support clinical decision-making and referral when needed.

Who Can Use It

Pouya-Heart can be operated by:

  • Nurses
  • Midwives (sages-femmes)
  • Pediatricians
  • Family physicians

No specialist training is required.

Where It Fits

Pouya-Heart is suitable for use in a wide range of settings, including:

  • Neonatal and maternity units
  • Pediatric clinics and private practices
  • Community
  • Rural & Mobile screening
  • Schools and kindergartens (as part of early screening programs)

Designed for Efficiency

  • Non-invasive
  • No consumables
  • No calibration
  • Portable and easy to deploy
  • Compatible with offline and online use

Pouya-Heart supports early screening without slowing down care.

Screening, Not Diagnosis

Pouya-Heart is a screening tool designed to help identify children who may benefit from further cardiac evaluation. Final diagnosis is always made by a pediatric cardiologist.

Clinical Decision Support

Pouya-Heart provides objective, clinically interpretable information from heart-sound analysis to support healthcare professionals in identifying congenital heart disease and guiding appropriate follow-up.
