Webbetween 2 leads. A wave that is travelling towards the positive (+) lead will inscribe an upwards deflection of the EKG; conversely a wave traveling away from the positive lead will inscribe a downward deflection. Waves that are traveling at a 90 degree angle to a particular lead will create no deflection and is called an isoelectric lead. WebJan 10, 2024 · An R wave is the first positive deflection from baseline. An S wave is a negative deflection that follows an R wave. When a complex is all positive, it is just an R wave; when it is all negative, it is called a QS. Regardless of the shape of the complex, ventricular depolarization waves are called QRS complexes ( Fig. 15-3 ). floaters hersentumorWebThus, the first question in interpreting an ECG is whether or not there is a sinus rhythm. A criterion for sinus rhythm is that P waves and QRS complexes appear 1-to-1, thus implying that the P wave causes the QRS complex. ...
