Electrocardiogram (ECG) is a medical test that is used to measure the electrical activity of the heart. It is a non-invasive procedure that helps in diagnosing various heart-related conditions such as arrhythmia, heart attack, and other problems related to the heart's electrical system. ECG machines come in various types with different numbers of channels - single, 3 channel, 6 channel, and 12 channel. The number of channels determines the number of electrical signals that can be recorded simultaneously from the heart. A single channel ECG machine records one electrical signal from the heart, while a 12 channel ECG machine records 12 different signals. At Global Biomedicals Inc, we deal in various types of ECG machines including single, 3 channel, 6 channel, and 12 channel machines. Our machines are designed to provide accurate and reliable results, making them essential for diagnosis and treatment of heart-related conditions. In conclusion, an ECG is an important diagnostic tool for heart-related conditions, and the number of channels in an ECG machine determines the number of electrical signals that can be recorded simultaneously.
