ECG Paper / Medical Chart Paper

An electrocardiography paper (ECG paper or EKG paper) is a medical chart paper used to record the electrical activity of the heart over a period of time.

ECG is a health diagnostic tool that facilitates healthcare providers in the observation and examination of the heart’s electrical signals, which can provide important information about a patient’s cardiac health.

ECG thermal paper is an essential component of ECG machines and medical devices used to record electrocardiograms.

ECG Thermal Papers used by Healthcare Specialists

ECG thermal paper is primarily used by healthcare specialists, including healthcare institutions such as hospitals, clinics, medical laboratories, and medical schools.

ECG paper is essential in several medical examinations, including cardiotocography (CTG), electrocardiogram (ECG), and electroencephalogram (EEG). High-quality ECG paper is precisely manufactured to produce easily interpretable and accurate recordings, featuring well-defined electrical tracing that can maintain cardiac data integrity for as long as 8-20 years.

Quality ECG Thermal Roll Ensures Accurate Readings

Not all thermal rolls are made the same. Thermal paper rolls vary considerably in terms of weight, dimensions, coatings, dyes, expected lifespan, and compatibility with different ECG machines and printers.

Choosing a top-tier ECG thermal roll is crucial, as uneven chemical coatings can result in poorly visible tracings.

Low-quality paper may additionally limit clinicians’ ability to conduct future consultations and comparisons due to the risk of missing or uneven protective layers, which can lead to image deterioration, shadows, and smudges.

While all thermal paper degrades with time, certain recording papers are specially coated to resist fading and deterioration.

ECG Chart Paper Readings are Important Records in the Digital Age

In the present day, many ECG machines are equipped to display the ECG trace on the screen. Nevertheless, it’s important to consider the printed output may incorporate additional data, such as pacing spikes, to provide contextual assistance during analysis.

Printed ECG Readings could serve as Legal Records

ECG paper records can potentially be used as legal documents in certain circumstances.

Medical Records

ECG chart paper records are often included in a patient’s medical records. These records are considered legal documents in the sense that they are used to track a patient’s medical history, diagnoses, treatments, and outcomes.

Insurance Claims

In cases where an individual’s health or life insurance claims are involved, ECG chart records may be used as evidence to support a claim. The insurance company may request medical records, including ECG paper readings, to verify if the claim is valid.

Disability and Workers’ Compensation Claims

ECG chart paper records may also be used as part of disability or workers’ compensation claims. These records can provide evidence of a medical condition that may entitle an individual to benefits or compensation.

Legal Proceedings

ECG chart paper records may be presented as evidence in legal proceedings related to medical malpractice or personal injury.

Research and Clinical Trials

ECG chart records generated during clinical trials or medical research studies may be used for legal purposes to support the findings and conclusions of the study. They can serve as documentation of the study’s methodology and results.

With so much of healthcare moving towards digitization and automation, the quality of ECG paper records should be maintained in compliance with medical record-keeping standards to ensure their validity and admissibility in legal contexts.

Why are ECG Chart Paper Results more important than Digital copies?

Legal Documentation

The ECG chart paper results serve as the official legal record of the test. It is typically signed and dated by the healthcare provider, which provides a level of authentication and accountability that a digital file may lack. This printed medical record can be used as evidence in legal proceedings, insurance claims, and for compliance with regulatory requirements.


ECG chart paper results are more accessible to a wider range of healthcare professionals. Not all healthcare providers or institutions have access to the same digital systems or software for viewing ECG readings. A printed ECG chart can be easily accessed among various members of the healthcare team, allowing for better collaboration in patient care.


Printed ECGs are portable and can be included in a patient’s medical records, which may be required for consultations with specialists, transfer between different healthcare facilities, or when seeking a second opinion. Digital copies may not be as readily available or easily accessed in these situations.

Legacy and Historical Records

Healthcare institutions often maintain printed copies of ECGs as part of a patient’s historical medical records. These records can be invaluable for tracking changes in a patient’s cardiac health over time, comparing current results with past ones, and monitoring the effectiveness of treatments.

Visual Inspection

ECG thermal paper allows for a detailed visual inspection of the ECG tracings. Healthcare providers may need to scrutinize the waveform patterns, intervals, and other subtle details to make accurate diagnostic assessments. A printed format provides a clear and tangible representation for this purpose.

Redundancy and Backup

Having both digital and printed copies can serve as a redundancy and backup system. If digital data is lost or corrupted due to technical issues, the printed ECG chart papers can still be available for reference and documentation.

Regulatory Compliance

In healthcare, compliance with regulatory standards is crucial. Some regulations and accrediting bodies may specify the necessity of maintaining printed records for auditing and quality assurance purposes.

Since printed copies of ECG results offer these benefits, it’s important that the quality of ECG thermal paper meets the specific requirements of different healthcare settings and jurisdictions.

Digital copies are also valuable for quick access, electronic sharing, and remote consultations. Therefore, a combination of both printed and digital records is often employed to ensure comprehensive patient care and record-keeping.

Importance of ECG Chart Paper in Healthcare Services


A heart specialist (Cardiologist) often uses ECG chart paper to record and interpret electrocardiograms (ECGs or EKGs) to assess the heart’s electrical activity.

Emergency Room (ER)

In emergency departments, doctors and nurses use ECG chart paper to quickly evaluate patients who present with chest pain, arrhythmias, or other cardiac symptoms.

General Practitioners (Family Doctors)

Family physicians may use ECGs as part of routine check-ups or when patients report cardiac symptoms.

Cardiac Nurses

Nurses who specialize in cardiac care use ECG chart paper to monitor patients’ heart rhythms and detect any irregularities in telemetry units or during patient assessments.

Paramedics and Emergency Medical Technicians (EMTs)

Emergency medical personnel often use portable ECG machines and ECG chart paper to assess patients’ heart rhythms in the field and during ambulance transport.

Technicians and Allied Health Professionals

Technicians and other allied healthcare professionals, such as electrocardiograph technicians, may operate ECG machines and record ECGs in various healthcare settings.

Medical Students

Medical students may use ECG chart paper as a learning tool to practice interpreting electrocardiograms and to gain familiarity with cardiac diagnostics.

Research Scientists

Researchers in the field of cardiology and related health research may use ECG chart paper in their studies to collect data on cardiac electrical activity.

In Conclusion

ECG chart paper is an essential tool for diagnosing and monitoring a wide range of cardiac conditions, making it a fundamental component of cardiovascular care in both clinical and emergency settings.
