Electrocardiograms (EKGs) are essential tools in diagnosing and monitoring heart conditions. This quiz will challenge your understanding of EKG interpretation, heart rhythms, and the significance of various waveforms. Whether you’re a seasoned professional or a curious learner, these questions will help you refine your skills and knowledge. Good luck and enjoy the challenge!
