An electrocardiograph is a medical device used by doctors to measure the electrical activity of a person's heart. It helps in diagnosing various heart conditions and provides valuable information about the heart's rhythm, rate, and overall health.
The electrocardiograph works by connecting electrodes onto the patient's skin, typically on the chest, arms, and legs. These electrodes detect the small electrical signals generated by the heart's contractions. Once the electrodes are connected, the machine records these signals and produces an electrocardiogram (ECG) graph.
The ECG graph shows the different waves and intervals that represent the electrical activity of the heart. By analyzing the shape, size, and timing of these waves and intervals, doctors can identify any abnormalities or irregularities in the heart's function. This information is crucial in diagnosing conditions like arrhythmias, heart attacks, and other heart diseases.

An electrocardiograph is a device that doctors use to measure the electrical activity of the heart. It works by connecting electrodes to the skin, recording the heart's electrical signals, and producing a graph called an electrocardiogram (ECG). This helps doctors diagnose heart conditions by analyzing the shape, size, and timing of the ECG waves and intervals.
