Description
Your smartwatch records ECGs. But do you truly understand what they reveal?
HeartLab transforms your ECG data into comprehensive cardiac insights that go far beyond what basic health apps show you. Professional-grade analysis, AI-powered explanations, and PDF reports your cardiologist will actually appreciate.
ADVANCED ARRHYTHMIA DETECTION
While standard ECG apps only detect Atrial Fibrillation (AFib), HeartLab identifies five types of heart rhythm irregularities:
• Atrial Fibrillation (AFib) - Irregular heartbeat originating in the atria
• Premature Atrial Contractions (PAC) - Early beats from the atria
• Premature Ventricular Contractions (PVC) - Early beats from the ventricles
• Bigeminy - Alternating pattern of normal and premature beats
• Trigeminy - Pattern of two normal beats followed by a premature beat
Our algorithms analyze every single heartbeat to find patterns that other apps miss completely.
COMPLETE HRV ANALYSIS
Get the full picture of your Heart Rate Variability with 12+ professional metrics:
• SDNN - Standard deviation of NN intervals, key indicator of overall heart health
• rMSSD - Reflects parasympathetic nervous system activity
• pNN50 - Percentage of adjacent intervals differing by more than 50ms
• Poincaré Plot - Visual representation of heart rate dynamics
• Cardiac Score - Our proprietary algorithm combining multiple metrics
The same metrics used in professional cardiac research, now accessible on your iPhone.
AI-POWERED EXPLANATIONS
Don't understand medical terminology? Our AI assistant explains your ECG results in plain language, answers your questions, and helps you understand what your heart data actually means. No more confusion about what those squiggly lines represent.
PROFESSIONAL PDF REPORTS
Generate detailed medical-grade reports that you can share with your cardiologist. Each report includes:
• Complete ECG waveform visualization
• All measurements and intervals
• HRV metrics and trends
• Detected anomalies and patterns
• Historical comparison
Doctors recognize and trust this format. Many cardiologists now request HeartLab reports during appointments.
SEAMLESS INTEGRATION
• Automatic ECG import from Apple Health
• No manual export or complicated setup
• Record your ECG, see analysis in seconds
• Complete historical data access
• Organized timeline view
100% PRIVACY-FIRST
Your ECG data never leaves your iPhone. All analysis is performed locally using advanced algorithms optimized for mobile devices. No cloud processing, no data uploads, no accounts required. Complete privacy, always.
