HRV Biofeedback with the eSense Pulse

The Mindfield eSense Pulse is a portable HRV biofeedback sensor that connects wirelessly to your smartphone or tablet via Bluetooth. Using medical-grade 1-channel ECG technology with a comfortable chest strap, it delivers accurate heart rate variability measurements for effective stress management training. Heart rate variability reflects your autonomic nervous system's balance between stress and relaxation. Through real-time biofeedback—including visual graphs, audio cues, and video feedback—you learn to actively influence your HRV and reduce stress levels naturally. The free eSense App provides comprehensive training programs, detailed HRV statistics with time-domain and frequency-domain analysis, and seamless data export as CSV or PDF reports. Combine with the optional eSense Respiration sensor to synchronize breathing exercises with your HRV training for enhanced results.

Understanding Heart Rate Variability (HRV) and Your Health

Your Heart: More Than Just a Pump

Your heart beats approximately 100,000 times per day, circulating oxygen-rich blood to every cell. But beyond pumping blood, your heart rhythm reveals crucial information about your health and stress levels.

What is Heart Rate Variability (HRV)?

The interval between heartbeats is never perfectly constant—even at rest, subtle variations occur. This natural fluctuation is called heart rate variability (HRV).

HRV reflects your autonomic nervous system's ability to adapt. During sleep, your heart beats slowly (~60 BPM). During stress or exercise, it can exceed 180 BPM. This adaptive capacity is essential for health and resilience.

Why HRV Matters

The greater your HRV, the more flexibly your body responds to demands. High HRV indicates:

  • Better stress resilience – your body recovers faster
  • Cardiovascular health – a well-regulated heart
  • Mental clarity – improved focus and calm

The Autonomic Nervous System

Your HRV is controlled by two opposing systems:

  • Sympathetic: "Fight or flight" – increases heart rate, prepares for action
  • Parasympathetic: "Rest and digest" – slows heart rate, promotes recovery

Healthy individuals maintain dynamic balance between these systems. Research shows higher HRV correlates with better cardiovascular health and cognitive performance.

Training Your HRV

With the eSense Pulse, you actively strengthen your parasympathetic response through real-time biofeedback. The app provides:

  1. Time-domain metrics: SDNN, RMSSD, pNN50
  2. Frequency analysis: VLF, LF, HF bands individually, LF/HF ratio, and Stress Index
  3. Visual feedback: Real-time HRV displayed as curve and bar graph, with evaluation of HRV regularity and amplitude

Regular HRV training builds awareness of your stress patterns and develops your capacity for relaxation—benefiting both physical health and mental well-being.

Mindfield eSense Product Comparison

The eSense Pulse measures your heart rate variability (HRV) — a key indicator of stress resilience and autonomic balance. Because it connects via Bluetooth, you can easily combine it with other eSense sensors that use the 3.5mm audio jack.

Popular combinations with eSense Pulse:Pulse + Skin Response: Monitor both HRV and electrodermal activity for comprehensive stress feedback • Pulse + Temperature: Combine heart coherence training with peripheral blood flow awareness • Pulse + Skin Response + Respiration: The ultimate trio for coherence breathing synchronized with HRV
