WORKSHOP Objectives
Review the basic concepts of normal cardiac anatomy and electrophysiology.
Establish the functional correlations of ECG signals and traces with the mechanical cardiac events.
Understand components and proper application of the technology used in ECG.
Learn about the up-to-date AHA guidelines and recommendations for a successful and accurate execution of ECG tracing.
Provide Trinity students with a simple method to evaluate ECG and identify abnormal traces effectively in various clinical settings.
ECGBASICS MATTER.
