Pick a rhythm and watch the 12-lead ECG beside electrograms from the HRA, His, coronary sinus and RV apex, with a step-by-step view of how the impulse spreads through a labeled heart. A device lab simulates interrogating pacemakers, ICDs and CRT systems, and a practice mode asks clinical reasoning questions.
