12-Lead ECG Interpretation

Nursing students and practicing nurses can learn 12-lead ECG interpretation at their own pace with this self-teaching guide.After reviewing the principles of 12-lead interpretation and basic ECG criteria, the focus turns to the interpretation of ECG strips. Using this text to gain understanding of the 12-lead ECG, you will be able to recognize a normal 12 ECG; locate the frontal plane axis; recognize a normal progression of the R wave in precordial leads; identify enlargements of the four chambers of the heart; identify right and left bundle branch blocks; identify hemiblocks, bifasicular, and trifasicular blocks; identify areas of myocardial ischemia, injury and infarction; state the ECG characteristics of supraventricular aberrancy and ventricular ectopy; recognize ECG changes that occur with certain drugs and electrolytes; and identify the Wolff-Parkinson-White syndrome.
