If the heart is beating steadily, it will produce the typical ECG pattern: The first peak (P wave) shows how the electrical impulse (excitation) spreads across the two atria of the heart. The atria contract (squeeze), pumping blood into the ventricles, and then immediately relax. chinese restaurant in seattle chinatown

WebMar 19, 2024 · During an ECG, up to 12 sensors (electrodes) are attached to the chest and limbs. The electrodes are sticky patches with wires that connect to a monitor. They record the electrical signals that make the heart beat. A computer records the information and displays it as waves on a monitor or on paper. WebThe PR interval measures time between the initial P wave and the initial deflection of the QRS complex. The QRS wave complex is the portion of the EKD that represents ventricular depolarization, and is a measure of the Q wave, R wave, an S wave. The ST segment or ST interval is the portion of time between the QRS complex and the start of the T ...

WebOnce you've determined that a P wave precedes each QRS complex, you must scrutinize the P wave for contour and size. The normal P wave is less than 0.12 seconds in duration, and the largest deflection, whether positive or negative, should not exceed 2.5 mm. An abnormal P wave may indicate atrial enlargement.

WebOct 8, 2024 · a) P wave: Represents atrial depolarization. Normally it is 2.5 mm wide and 2.5 mm high. Tall P waves = right atrial enlargement (RAE) Wide P waves = left atrial enlargement (LAE) Wide and tall or bi-peaked P waves = bi-atrial enlargement (BAE). b) PR interval represents a delay in conduction in the AV node.
