ECG Device Testing

The electrocardiogram, more commonly known as an ECG, is an electrocardiogram (ECG) test that is used to measure the electrical signals generated by the heart. The ECG device tests the electrical activity of the heart by recording the heart’s response to the electrical signals created by the heart muscle. This electrical activity of the heart is transferred to paper or digital paper through an electrode attached to the skin. The electrical signals created by the walls of the heart are picked up by the electrodes and then converted into numbers. It is then be downloaded into a computer program that is used to analyze the results and help diagnose problems with the heart.

The ECG device testing can ensure that your device is working as per international norms.

Helix India offers a wide range of ECG device testing machines that are being used at an advanced rate. It is imperative that the device need to be checked for working conditions and ensure that it is accurately functioning.

Features of ECG devices

Features of the ECG device testing varies on different ECG machine testing types, which includes 1-lead, 3-lead, 5-lead and 12-lead machines. Multichannel ECG test system comprises of built-in test waveforms, which include CAL Waveforms (16x), ANE Waveforms (3x), Biological Forms (100x), and Noise Waveforms (as per IEC 60601-2-51:2003).

ECG device testing is customized and designed according to the different functions, parameters, and specifications. Some of the ECG device testing variants at Helix India are as follows:

  • HRS200 - Heart Rate Simulator
  • CMRR 2.0 - ECG Common Mode Rejection Ratio Testing System
  • MECG 2.0 - Multichannel ECG Device Testing System
  • SECG 4.0 - Single Channel Device Testing System
  • ECG Set
  • SEEG 100 - Single Channel ECG Device Testing System

Recording the ECG Signal

Two electrodes are placed on the skin in the lower chest and one on the neck, and the electrical activity of the heart's upper chambers and ventricles is assessed. High-frequency alternating currents are transmitted through the chest electrodes, creating an electrical signal that is displayed on a computer.

Recording the ECG waveform

ECG waveform analysis is the process of calculating the electrical activity of the heart by accurately placing the electrodes in accordance with the American Heart Association (AHA) recommendations. P wave, Q wave, R wave, S wave, T wave and U wave are the normally seen ECG Waveform. ECG Device testing can be included with the notable parameters (region) such as PR interval, QRS interval (also called QRS duration), QT interval and RR interval.

Heart rate variability (HRV) Analysis

HRV analysis is a measurement tool on ECG signals of how consistent and fast your heartbeats are. A low HRV is indicative of a stressed, over-taxed and unhealthy heart. High HRV, on the other hand, is indicative of a well-functioning, healthy heart. HRV can be measured in many ways, including by wearing activity monitors, using a heart rate variability monitor, or using scientific formulas.
