Time is measures on the horizontal axis millivolt (mV) a unit of measurement to indicate voltage on the ECG tracing. Voltage is measured on the vertical axis multichannel recorder an ECG machine that monitors all 12 leads but records three leads at a time and switches automatically, recording each of the four sets of three leads. output display the part of the ECG machine that displays the tracing for the electrical activity of the heart, usually in electronic or a printed form on a 12-lead ECG machine precordial lead a type of lead placed on the chest in front of the heart; known as the V lead serial ECG comparison multiple and frequent ECG tracings recorded at intervals based on the patient’s condition and compared to monitor changes signal processing the process within the ECG machine that amplifies the electrical impulse and converts it to a mechanical action that appears as a waveform on the output display speed control a control on the ECG machine that regulates how fast or slow the paper runs during tracing tachycardia a fast heart rate, usually greater than 100 beats per minute unipolar lead a type of ECG lead that measures the flow of electrical current in one direction only Facebook Google+ Like 0 Twitter Review 78% 78%
