Electrocardiograms (ECGs) are a cornerstone of modern cardiology, offering essential insights into the electrical activity of the heart. For healthcare institutions—hospitals, clinics, medical centers, and large-scale health systems—understanding the appropriate use of different ECG modalities is critical for optimizing diagnostic accuracy and improving patient outcomes. The two most commonly used types are the resting ECG […]

A resting ECG, also known as a Ruhe-EKG in German, is one of the most commonly used diagnostic tools in modern cardiology. For medical equipment distributors, large healthcare facilities, hospitals, and clinics, understanding and providing access to this essential technology is key to delivering comprehensive cardiac care. It provides valuable insights into the electrical activity […]

Selecting the right resting ECG machine is a strategic decision for healthcare institutions and medical device distributors. In environments where accurate diagnostics, operational efficiency, and system interoperability are essential, the right ECG solution directly influences clinical outcomes and organizational productivity. This guide outlines the most critical features to consider when choosing a professional-grade resting ECG […]

Electrocardiographic stress testing (Stress ECG) remains a vital, non-invasive diagnostic method used by cardiologists worldwide to assess heart performance under physical exertion. As of 2025, the clinical demand for systems that are accurate, user-friendly, and digitally integrative has never been higher. Among the industry’s most trusted providers, Norav Medical continues to lead with innovative, high-performance […]

For more than 150 years, ECG recording technology has been developing and improving. Doctors now have access to multi-channel recorders, long-term (tens of days) ECG recording devices, and wearable recorders integrated into smartphones, watches, bracelets, etc. Data processing algorithms are also improving, including those using artificial intelligence, which is developing very rapidly in medicine. This […]

Cardiographs can be single-channel and multi-channel. In the first case, the device records cardiograms in several leads sequentially. These are very simple devices by design. Due to their light weight, which rarely exceeds 1 kg, ability to work from battery, and mobility, they are most often used in ambulances. Single-channel electrocardiographs can be purchased very […]

ECG is a record of the changes in electric potentials occurring during the contraction of the heart. Electrocardiography forms the basis of many other diagnostic investigations – Holter monitoring, bicycle ergometry, transoesophageal recording of ECG, pharmacological tests with ECG, remote ECG and monitoring in intensive care or during operations. Electrocardiography is absolutely harmless and painless […]

As Wendell Willkie once mentioned:” There are no distant places any longer: the world is small and the world is one.” This expression accurately stresses what is happening in almost all spheres of human activity, including the healthcare provision. Indeed, telemedicine has revolutionized healthcare delivery, making medical services remote and instant. The contemporary paradigm which […]
