![]() ![]() Sinus rhythm, rapid progression of R-waves in precordial leads. Discrete ST-segment depressions in leads V5-V6. R-waves have low amplitude, suggesting low voltage (see below). Also note that this chapter is accompanied by a video lecture: Video lecture: The Normal ECG, which covers all topics discussed below. ![]() Thus, in this chapter, you will learn the physiological basis of all ECG waves and how to determine whether the ECG is normal or abnormal. Although heart rhythm will be discussed in detail in the next chapters, fundamental aspects of rhythm will also be covered in this discussion (refer to Normal Rhythm and Arrhythmias). A rather extensive discussion is provided in order to give the reader firm knowledge of normal findings, normal variants (i.e less common variants of what is considered normal) and pathological variants. This chapter will focus on the ECG waves in terms of morphology (appearance), durations and intervals. At the heart of ECG interpretation lies the ability to determine whether the ECG waves and intervals are normal. This is arguably one of the most important chapters throughout this course. ECG Interpretation Part 1: definitions, criteria, and characteristics of the normal ECG (EKG) waves, intervals, durations & rhythm ![]()
