The waves or deflections shown on the ECG are named for the letters P, Q, R, S and T. R waves are the first upward deflection within a series known as the QRS complex. As part of the QRS complex, an R wave is an important indicator of cardiac health. Cardiologists and other ...
B. What does the QRS complex represent? C. What does the T wave represent? When the SA node does not function properly, the AV node takes over pacing the heart and produces what is known as a junctional rhythm. Explain why we would NOT see a P wave on the EKG of a patient wi...
