Chapter 02: Introduction to the 12-Lead ECG TRUE/FALSE 1. The point where the QRS complex and ST segment meet is called the ST-junction or J-po ANS: T The point where the QRS complex and the ST segment meet is called the ST-junction or J-point. OBJ: Identify the J-point and ST-segment deviations. 2. If the wave of depolarization (electrical impulse) moves toward the positive electrode, the waveform recorded on ECG graph paper will be upright (positive deflection). ANS: T If the wave of...
