Ecg Pqrst Wave. The ecg records the electrical activity that results when the heart muscle cells in the atria and ventricles contract. A normal heart beat contains a p wave a qrs complex and an st segment. The p wave is the first wave in the normal ecg tracing assuming sinus rhythm is present that represents the electric current originated from the sa node that travels along the right and left atrial chambers signaling atrial contraction thus transferring blood into the ventricles. The ecg learning center describes the characteristics of a normal ecg.
Einthoven continued to use pqrst to identify waves in the ecg recorded with the string galvanometer. 7 the u wave was detected only in ecgs made with the string galvanometer. This will allow you to determine what area of the ecg represents one heart beat. How to read an electrocardiogram ecg part 1 pqrst waves the electrocardiogram ecg is a diagnostic tool that measures and records the electrical activity of the heart in detail. From the length of a heart beat on the ecg trace you will be able to calculate the heart rate. Atrial repolarisation is called ta wave.

The region between the qrs complex and t wave is referred to as the st segment. From the length of a heart beat on the ecg trace you will be able to calculate the heart rate. Atrial repolarisation is called ta wave. How to read an electrocardiogram ecg part 1 pqrst waves the electrocardiogram ecg is a diagnostic tool that measures and records the electrical activity of the heart in detail. Ecg interpretation includes an assessment of the morphology appearance of the waves and intervals on the ecg curve. This will allow you to determine what area of the ecg represents one heart beat.
