Objective: To determine the effectiveness of ECG interpretation workshops as a useful tool in medical education for teaching the integrated cardiovascular module for undergraduate medical students. Study design and setting: Cross sectional (pre and post workshop quiz) at Jinnah Medical and Dental College over four months from August-November 2019. Methodology: Total 80 undergraduate medical students participated in the training session.

Seventy (87%) students had a satisfactory score of which five students were outstanding and only five (6%) scored unsatisfactory. Feedback form filled and the comments were recorded. Conclusions: It was found by post workshop quiz scores and feedback regarding interdepartmental integrated activity results in a better teaching and learning outcomes. Post workshop Quiz scores indicated the improvement in ECG interpretation and skills.
