For years, cardiologists examined paper charts of ECG signals to create an averaged ECG complex. They took each individual cardiac cycle, measured each part of the complex with a ruler, wrote down each value, and calculated the means to derive an averaged ECG complex. As you can imagine (or have experienced), this task took a great deal of time and patience. When the need arose to analyze two or more different scenarios (e.g., baseline response), the task had to be performed even more carefully, to accurately comparison of the ECG.
The AcqKnowledge software has a powerful averaging feature that automatically derives an averaged signal from a specific number of cycles (averaging is found in the Peak Detection menu). And, you can easily compare two, three, or more averaged ECG signals with just a few mouse clicks.
The NICO Smart Amplifier is specifically designed to measure thoracic impedance for performing noninvasive cardiac output measurements. The amplifier terminates in two connectors for impedance (Z) and its derivative (dZ), and has a 3 m cable that connects directly to an AMI100D Amplifier Input Module. Use with EL526 strip electrodes and CBL246 adapter or with EL500 […]
