About ECG Paper Roll

ECG paper, also known as electrocardiogram paper, is a specialized graph paper used to record the electrical activity of the heart. It's a crucial component of an electrocardiograph machine and helps doctors analyze heart function. The paper has a grid-like pattern that allows for precise measurement of the heart's electrical signals, which are recorded as waveforms. Key Features of ECG Paper: Grid Pattern: The paper is divided into small and large squares. Horizontal Axis (Time): Each small square represents 0.04 seconds, and five small squares (one large square) represent 0.2 seconds. Vertical Axis (Voltage/Amplitude): The vertical axis represents the voltage or amplitude of the electrical signals, with standard calibration often being 10 mm (10 small boxes) equal to 1 mV. Paper Speed: The standard paper speed is usually 25 mm/sec, but it can be increased to 50 mm/sec for better waveform definition. How it Works: 1. ECG Machine: An ECG machine records the heart's electrical activity through electrodes placed on the body. 2. Signal Recording: The machine translates these electrical signals into waveforms on the ECG paper. 3. Analysis: The waveforms are then analyzed by doctors to assess the heart's rhythm, rate, and overall function. Importance: ECG paper allows for accurate measurement of ECG intervals and amplitudes, which are essential for diagnosing various heart conditions. It helps in identifying abnormalities such as arrhythmias, heart attacks, and other cardiac issues. It also helps monitor the heart's response to treatment.
