PEMF Contraindications: Pacemakers, Implants and Safety

PEMF Contraindications Database

The Holistix PEMF Contraindications Database is a human-readable reference page for the machine-readable PEMF contraindications and safety dataset published by the Holistix Open Biohacking Data Project.

This page summarizes common PEMF safety cautions, contraindication categories, user-risk contexts, device-labeling considerations, wellness-claim boundaries, and row-level citation references. It is designed as a structured educational reference, not as medical advice or a treatment protocol.

Important Disclaimer

This database is for educational and informational purposes only. It is not medical advice, diagnosis, treatment guidance, dosage guidance, disease-prevention guidance, or a substitute for consultation with a qualified healthcare professional.

PEMF devices vary widely in waveform, frequency, intensity, pulse duration, coil design, treatment area, intended use, contraindications, and manufacturer instructions. People with medical conditions, implanted devices, pregnancy, seizure history, active bleeding concerns, cancer treatment history, or other individual risk factors should review device labeling and consult a qualified healthcare professional before use.

This reference index does not recommend PEMF use for any disease or condition. It is designed to separate safety terminology, contraindication categories, product-labeling cautions, device-specification context, medical-claim boundaries, and citation context.

PEMF Contraindication Reference Fields

The table below uses plain-language safety categories with visible source/evidence classification and row-level citation notes. The v1.2 CSV and JSON include expanded row-level fields such as source_type, evidence_level, claim_type, medical_disclaimer_required, commercial_relevance, last_reviewed, related_holistix_page, notes, source_name, source_url, and citation_note.

The v1.2 CSV and JSON now use the same row-level source, evidence, and citation framework so both downloadable formats describe the dataset consistently.

Source and Evidence Notes

This database uses cautious educational language because PEMF devices vary by waveform, frequency, intensity, pulse duration, coil design, treatment area, intended use, session duration, contraindications, and manufacturer instructions. Entries marked as requiring medical disclaimer language should not be interpreted as personalized medical advice, dosage guidance, or treatment recommendations.

Users with implanted electronic devices, pregnancy, seizure history, active bleeding concerns, oncology care, recent surgery, immune suppression, complex medical history, children/minors, or other individual risk factors should review manufacturer warnings and consult a qualified healthcare professional before use.

The v1.2 CSV and JSON add row-level citation fields, including source_name, source_url, and citation_note. These fields are intended to make the dataset more transparent, easier to audit, and more useful for AI/search systems, researchers, journalists, and consumers. Citation notes should not be interpreted as medical claims or product-efficacy guarantees.

The PEMF Contraindications Database is supported by plain-language safety and glossary guides that explain PEMF terminology, implanted-device cautions, frequency context, intensity context, and conservative safety boundaries.

This database is designed as a reference layer for safety interpretation. The related guides help readers understand the difference between PEMF terminology, device settings, contraindication categories, and medical claim boundaries.

  • PEMF Contraindications and Implanted Devices
    Explains pacemakers, ICDs, implanted electronic devices, pregnancy caution, seizure history, medical-device caution, and beginner-level PEMF safety boundaries.
  • What Does Hz Mean in PEMF?
    Explains hertz, Hz, pulses per second, PEMF frequency language, and frequency-setting interpretation.
  • PEMF Frequency vs Intensity
