This educational simulator allows users to explore the relationship between the heart's electrical activity and ECG waveforms. It offers interactive workspaces to visualize cardiac processes, ion channel functions, and simulate cardiac rhythms. Users can learn and test their knowledge through quizzes, with both free and paid features available.

October 16, 2026
Learn the mechanisms behind ECGs, from cell currents to cardiac rhythm. - Added Ventricular Action Potential with synchronized Luo–Rudy I membrane voltage, ion currents, and gates. Pause at the sodium-current peak. The standard model and stimulus adjustment are free; conductance adjustment, suppression experiments, and standard-trace comparison are included in the existing Pro purchase. - Added Cardiac Rhythm. Follow activation from the sinus node to the ventricle and adjust sinus cycle, conduction speed, and AV delay. All features, including schematic bradycardia, tachycardia, and AV-block examples, are free. - Expanded Ion & ECG adjustments, including Na⁺ and H⁺ (pH), and clarified clinical connections and differences from the reference. Added voltage ticks and units to the action-potential plot. - Improved single-lead and 12-lead comparisons, including representative pediatric, fever-related heart-rate increase, and higher-BMI examples. ECG Mechanism and comparison selections now remain independent. - Refined pediatric waveforms, bundle-branch conduction, atrial fibrillation, ST changes, and ECG/3D consistency. Included representative P-wave flattening and PR prolongation with high K⁺, and ST depression in the LVH strain pattern. - Improved the 3D heart, membrane diagram, two-lead comparison, and playback alignment. Electrode placement includes all 10 electrodes, including neutral RL. - Improved text, buttons, and layouts. Wider screens show quiz waveforms alongside answers and explanations. Refined the iPhone feature list, navigation, and landscape layouts. - Clarified model purposes and limitations, and made phase, gate, and current explanations more accurate when conditions change. Educational models only—not for diagnosis or treatment decisions.

ECG Vector Pro
All leads, clinical patterns, and editing.
ECG Vector is an educational simulator designed to help users understand how the heart's electrical activity generates ECG waveforms. It provides interactive workspaces for exploring cardiac mechanisms, ion channel functions, and simulating rhythms.
The free version of ECG Vector includes access to the Adult Normal and Right Bundle Branch Block ECG patterns, all standard 12 leads, fixed electrode placement, four guided Ion & ECG examples, and sample comparison and quiz content. It also offers the standard ventricular-cell model with stimulus adjustment and playback.
The one-time ECG Vector Pro purchase unlocks unrestricted adjustment of Ion & ECG features and their synchronized 12-lead response. It also provides ventricular-cell conductance adjustment, suppression presets, additional pediatric and clinical patterns, custom leads, electrode editing, and the complete comparison and quiz libraries.
Yes, ECG Vector is available on Mac, iPhone, and iPad, allowing users to learn across different platforms.
No, ECG Vector is not a subscription-based application. The Pro version is unlocked with a single, one-time purchase.
ECG Vector has an age rating of 4+, making it suitable for a wide range of users interested in learning about the heart.
ECG Vector was last updated on October 16, 2026, with version 1.3.1. This indicates a recent update, suggesting ongoing development and support.
No, ECG Vector is strictly for educational purposes and should not be used for diagnosis, treatment decisions, or patient-specific prediction. The simulation models are educational approximations.
