Electrocardiograph, professional, single-channel

An electrocardiograph (ECG) in this category is a professional-grade device used in clinical settings to capture and analyze the heart’s electrical activity. By recording signals from a single lead configuration at a time, it generates a graphical display to help physicians diagnose cardiac conditions like arrhythmias or ischemia.

These devices are typically regulated as medical technology, often requiring compliance with safety and performance standards before market entry. They may be sold as standalone units with built-in displays or as components (like cables) paired with external systems, depending on their intended use and design.
