WebThe time it takes to activate the atria is represented by the P wave on the electrocardiogram (ECG). After depolarizing the atria, the impulse enters the atrioventricular (AV) node, which is located in the inferior septal region of the right atrium, where a delay occurs. This delay allows time for the atria to contract and fill the ventricles. WebStudy tip: The P-wave represents ATRIAL DEPOLARIZATION (depolarization is a big, fancy word for CONTRACTION). QRS Complex: The next area you see is a big spike. This spike is called the QRS complex. The bundle of His, bundle branches, and Purkinje fibers are responsible for this.
WebAn electrocardiogram is a measurement of the electrical activity and impulses created by the heart. It is most often referred to as an EKG or ECG. Electrodes are placed on the chest and each electrical impulse is translated into a wave pattern on a grid. The grid allows for the calculation of the duration and amplitude of each impulse, as well as whether the … WebAn ECG (electrocardiogram) is a test to check the electrical activity of the heart. ECG measures the atrial and ventricular depolarization and repolarization in the form of waves. …
