What is ECG Wave-Maven?Proficiency in electrocardiogram (ECG) interpretation
is an essential skill for medical students, housestaff, and clinicians. However, medical school and postgraduate resources to develop and upgrade the necessary high level of "ECG literacy" are severely limited. Further, current textbook and classroom instructional materials do not adequately integrate ECG interpretation into specific contexts where waveform findings must be correlated with other clinical data. We have begun to address the limitations in traditional approaches to ECG pedagogy by creating the infrastructure for a unique web-based tutorial.
