HeartMath technology (emWave and Inner Balance) is designed for stress reduction and resilience training, not as a medical device.
-
Key Benefits: Improves mental clarity, creativity, and athletic performance (“The Zone”).
-
Medical Considerations:
-
Pacemakers: Generally compatible, but if the pacemaker is always pacing the heart, HRV changes won’t be visible.
-
Beta Blockers: Do not interfere and may actually make the sensor reading easier.
-
Arrhythmias: May cause “Artifacts” (red lines); persistent irregularities can make coherence scoring difficult.
-
-
Safety: Sensors are completely safe with no risk of shock. The Bluetooth version uses Low Energy (BTLE) with significantly less EMF than a mobile phone.
Important: Always consult your healthcare professional before using HeartMath as an adjunct to any medical treatment.
1. Purpose and Scope of HeartMath Technology
HeartMath products are intended for stress education and resilience training. They are not medical devices and are not marketed to treat, cure, or diagnose specific conditions. However, many users find that reducing stress levels provides significant support for their overall wellbeing. We recommend consulting with your physician to see how HeartMath might fit into your current health program.
2. Performance and Lifestyle Benefits
Beyond basic stress management, achieving high coherence offers several advantages:
-
Mental Clarity: Enhances focus, business communication, and creative problem-solving.
-
Athletic Excellence: Helps athletes enter “The Zone”—a high-performance state characterized by poised, alert calmness.
-
Daily Resilience: Improves the ability to stay balanced during chaotic or changing environments.
3. Compatibility with Heart Conditions & Devices
-
Pacemakers & Vagal Stimulators: Most users can use the system. However, if your device is programmed to pace your heart constantly, the software will only reflect that fixed pacing and won’t show the natural Heart Rate Variability (HRV) driven by your nervous system.
-
Arrhythmias (AFib, PVCs, etc.): Irregularities appear as Red Lines (Artifacts). While the system can handle occasional skipped or extra beats, persistent arrhythmias may prevent the software from calculating an accurate coherence score. In these cases, users should focus on the heart rhythm graph itself to look for “sine-wave-like” patterns.
-
Beta Blockers & Calcium Channel Blockers: These medications do not interfere with the technology. Because they relax blood vessels, they often make it easier for the sensor to read your pulse.
-
Vasoconstrictors: These will likely interfere with the sensor’s ability to get an accurate reading.
4. Safety, Electricity, and EMF
-
Electric Shock: There is zero risk of electric shock. The sensors are completely isolated in plastic enclosures and use extremely low voltage (max 3.3V). For comparison, this is a fraction of the power in a standard 9V smoke alarm battery.
-
EMF Radiation: The Inner Balance Bluetooth sensor uses Bluetooth Low Energy (BTLE). Its output power is 0.5 mW or less—roughly 500 to 4,000 times lower than a typical mobile phone. Furthermore, the Bluetooth transmitter is located in the garment-attached module, not the ear clip itself.
5. Usage Limitations
The technology may be difficult to use for:
-
Children who are unable to sit still for the duration of a session.
-
Individuals with intense, persistent heart irregularities that prevent a consistent pulse lock.
