Cardiovascular Essentials for Ambulatory Nurses – Foundations-Video: Cardiovascular Diagnostics Part 1

Video Transcription

Video Summary

In this video, Jenny Kennedy, a nurse and VP of Care Transformation, provides a comprehensive overview of electrocardiograms (EKGs) and their interpretation. She begins by discussing the technique of EKGs, explaining that they record the electrical pathway within the heart, including depolarization and repolarization. Kennedy then goes on to explain the different components of the EKG waveform, such as the P wave, QRS complex, ST complex, and J point, and their significance in identifying abnormalities in the heart's electrical activity. She also discusses the importance of proper placement of electrodes and provides guidance on where to place them. Additionally, Kennedy discusses the different leads used in EKGs and their respective positions on the body. She then moves on to the interpretation of EKGs, emphasizing the importance of assessing the rate, rhythm, presence of P waves, any conduction blocks, and changes from the patient's previous EKGs. Kennedy presents different normal and abnormal rhythms, including sinus rhythm, atrial fibrillation, atrial flutter, ventricular tachycardia, ventricular fibrillation, and ventricular asystole. She explains the characteristics and implications of each rhythm and highlights the necessity of prompt action for certain life-threatening rhythms. Kennedy concludes by encouraging healthcare professionals to familiarize themselves with EKG rhythms and offering further assistance for any questions.
