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...

P wave - Answer Usually round & upright 0.06 to 0.12 seconds QRS complex - Answer normal duration 0.4 to 0.10 (one small box to 2.5 small boxes) PR interval - Answer normal duration 0.12 to 0.20 ST segment - Answer should be isoelectric the "J point" should come back to baseline 10 times method - Answer count the number of R waves in a 6 second strip and multiply by 10 Big block method - Answer Divide the number of big boxes between 2 consecutive R waves into 300 ...

Electrocardiogram (ECG) - Since you can't see the heart beating we use a ECG to provide a picture that replicates the actual cardiac issue. Myocardial Infraction (MI) - Heart Attack -Have abnormal rhythms. -Death of cardiac muscle due to ischemia Doe the ECG machine monitor or control the hearts rhythm? - Only monitors Straight line when machine is turned on but not connected to the patient - Isoelectric = no current It is straight because there is a balanced electrical force field. Thi...
