What do the P QRS and T waves represent?The P wave in an ECG complex indicates atrial depolarization. The QRS is responsible for ventricular depolarization and the T wave is ventricular repolarization.
What information is recorded by lead 1?Lead I records electrical difference between the left and right arm electrodes. In picture B above, the negative electrode is on the right arm and the positive electrode is on the left leg (left lower chest). This is lead II. Lead II records electrical differences between the left leg and right arm electrodes.
Which of the following waves should an EKG technician used to determine the regularity of the ventricular rate?NHA EKG. Why is the R wave taller than the P wave?Why is the R wave taller than the P wave on the ECG graph cycle? The ventricles are larger than the atria, requiring a stronger electrical stimulation to depolarize them.
