EKG Course Introduction Course Overview: This course begins with a discussion of the physiology of cardiac conduction, and then covers the basics of how to read an EKG strip, and the normal components of the EKG waveform. We will then examine basic cardiac dysrhythmias, including atrial and ventricular dysrhythmias, and blocks. Finally, selected nursing diagnoses for patients with dysrhythmias will be offered, along with suggested associated nursing interventions. See Objectives for speci...

Basic EKG Dysrhythmia Identification Useful to help determine EKG dysrhythmias on EKG Indicates early ventricular repolarization Normally not depressed more than 0.5 mm May be elevated slightly in some leads (no more than 1 mm) PR intervalIndicates AV conduction time Duration time is 0.12 to 0.20 seconds QT intervalIndicates repolarization time General rule: duration is less than half the preceding R-R interval Sinus Bradycardia Rate 40-59 bpmP wave sinusQRS normal (.06-...
