MODIFICATIONS

ECG Waveform Realism Enhancement

• Individual cardiac cycle desynchronization implemented via random time offset initialization
• Per-crew-member heart rate variability algorithm deployed (±5% baseline variation)
• Unique waveform morphology generation for P, QRS, and T wave components
• Baseline electrical interference simulation added to all ECG channels
• P wave amplitude variation: 0.85-1.0x multiplier per individual
• QRS complex morphology variation: 0.95-1.10x multiplier per individual
• T wave amplitude variation: 0.90-1.08x multiplier per individual

Heart Rate Telemetry Display

• Real-time BPM readout added to upper-right corner of ECG strip
• Display refresh rate: 500ms interval for smooth tracking
• Heart rate calculation: 57-63 BPM baseline (unstressed, full health)
• Stress response: +5 BPM per stress point
• Injury response: +20 BPM maximum at critical health (<30%)
• Asystole indication: "---" displayed when health = 0
• Monospaced numerics prevent UI shifting during value updates

Waveform Generation Algorithm

• Random phase offset: 0-10 range applied to cardiac timing
• Initial time parameter: 0-100 randomized offset eliminates synchronization artifacts
• Heart rate variability coefficient: 0.95-1.05 per crew member
• Baseline electrical variation: ±0.075 amplitude offset per individual
• Electrical noise floor: 0.004 amplitude constant (simulates lead interference)

OPERATIONAL IMPROVEMENTS

• No two crew members display identical ECG waveforms
• Heart rate responds dynamically to stress and injury state changes
• Flatline detection properly indicates zero heart rate
• ECG visual distinctiveness enhanced for rapid crew status assessment

COMPATIBILITY

All existing session data remains compatible. No migration required.
