ECG Review for practical 1: For the practical you will be required to provide an answer for each ECG that includes the name of the ECG, what is the disorder, why it is abnormal, and give the rate when required. Be specific. Don’t overwrite with excess unnecessary information. We will review in class on _______.Until then go through these slides and fill in the needed information via your notes. If you do not have this filled out you will not be allowed to stay for the review.

RATE

Normal Sinus Rhythm In this example, the heart rate is 68 beats · min–1.

Sinus Bradycardia

Sinus Tachycardia In this example, the heart rate is 136 beats · min–1.

Myocardial Infarction See Figure 11.3, Page 120 for reference Myocardial Infarction Reprinted, by permission, from E. Stein, 1992, Rapid analysis of electrocardiograms, 2nd ed. (Philadelphia, PA: Lea & Febiger), 150. Note the Q wave may be the only remaining evidence of the MI
