ECGs are tricky, and they can be even more challenging to interpret in children. The ranges are different from adults, the variations are subtler, and in busy clinical environments, there’s often little time to flip through a PDF or rely purely on memory.
Dr Hassan Nassar, a senior Emergency and Intensive Care Medicine trainee based in the UK with a subspecialty in Paediatric Emergency Medicine, has been in that moment and has seen it play out more times than he can count. Picture the scene: a junior doctor stands over an ECG printout, eyes flicking over the lines and spikes, trying to make sense of them.
The numbers, the intervals, the waveforms: it all makes perfect sense in the lecture theatre. But in day-to-day practice, especially for clinicians earlier in their training, it’s easy to feel uncertain about how to approach an ECG in a structured, methodical way.
Wanting to bring clarity to these high-pressure learning moments, Dr Nassar set out to create an educational tool that reinforced how ECG interpretation is taught by experienced clinicians: a clear, stepwise approach that supports learning without replacing clinical judgement. The intention was always that ECG interpretation would be undertaken alongside clinical history and confirmed by a clinician formally signed off to do so, in line with local workplace policy.
He wanted something interactive rather than passive; quick to access, reliable even in areas with poor connectivity, and simple enough to build without a large team or budget. As Dr Nassar recalls, the real challenge was:
How do you make that kind of learning happen without a big team, a huge budget, or months of extra time?
Finding Zoho Survey, Dr Nassar created a guided, logic-driven walkthrough that follows the same stepwise framework an experienced clinician would use when interpreting an ECG. Users work through rate, rhythm, intervals, and waveform features in sequence. For each step, the survey logic presents the next relevant question and generates a structured report based on the user’s answers.
Importantly, the tool does not generate a diagnosis and is not designed to provide a final interpretation. Instead, it mirrors how an experienced clinician would document their ECG interpretation: step by step, with each element considered in the context of the clinical picture. This logic branching is designed to mirror established educational ECG interpretation frameworks, presented in an easily understood format.
Completing the survey doesn’t feel like filling out a form; it feels like being guided through a structured educational approach to ECG interpretation.
When users finish the survey, they receive an instant, ready-made report that’s visual, clutter-free, and easy to read. The resulting report reflects the user’s inputs in the same way a clinician might record their findings in the notes, making it particularly useful for teaching trainees and clinicians in the earlier stages of their careers.
Charts and summaries help learners review how they approached each part of the ECG, reinforcing good habits and supporting reflective learning. All of this is built directly within Zoho Survey, with no coding and no development team.
Thanks to Dr Nassar’s creativity and Zoho Survey’s flexibility, the ECG learning aid was adopted across multiple settings, including different hospital departments and GP surgeries. In all cases, it has been used strictly as a learning aid, with ECG interpretation undertaken in conjunction with clinical history and confirmed by clinicians signed off to do so, in accordance with local governance and workplace policy.
Reflecting on the project, Dr. Nassar said:
I’ve used the tool at teaching events, during clinical placements, and via QR codes on educational posters. Zoho Survey acts as both the teaching interface and a learning record. The flexibility of the platform has allowed the tool to be shared and updated without the need for a dedicated developer, making Zoho an integral part of delivering smarter and scalable medical education.
Zoho Survey is honoured to support innovative clinicians like Dr Hassan Nassar. His work shows how simple, well-designed survey logic can support structured medical education, helping trainees and developing clinicians build confidence in ECG interpretation without replacing formal clinical judgement.
