👉 Electrochronometer is a device used in medical diagnostics to measure and record the electrical activity of the heart. It can be used to monitor the function of the heart, including its rate of contractions, atrial and ventricular electrical activity, and other cardiac signals. This technology has been widely adopted in various diagnostic tests for detecting arrhythmias (tachycardia, tachypnea, etc.), as well as for monitoring the effectiveness of pacemakers or defibrillators
