Use Case Overview

HeartWise: one visualization,
eight transformative uses

HeartWise is a 3D cardiac visualization tool built for every stakeholder who needs to understand what a heartbeat means from a cardiologist explaining a diagnosis, to a student learning anatomy at midnight, to a community health worker in a rural clinic with a phone as their only diagnostic tool.

Eight User Stories, One Tool

HeartWise serves doctors explaining diagnoses to patients, educators teaching the next generation of clinicians, students practising independently, specialists conducting telemedicine across continents, smartwatch users monitoring for arrhythmia and heart attack risk, post-surgical patients tracking recovery at home, community health workers in regions without echocardiography access, and individuals managing anxiety through real-time cardiac feedback.

Who are the users?

A Spectrum of Stakeholders

Cardiologists, medical educators, students, remote specialists, smartwatch users, post-surgical patients, rural health workers, and anyone managing a stress- or anxiety-driven cardiac response across every level of medical literacy.

What do they share?

A Need for Visual Clarity

Whether explaining, learning, monitoring, or managing, every user benefits from the same thing: a live waveform and plain-language context that turns a raw BPM number into something meaningful and actionable.

How does HeartWise help?

One Interface, Every Context

A single BPM input drives a real-time 3D heart, a color-coded zone indicator, and a synchronized EKG strip. The same interface that helps a doctor explain tachycardia also helps a student study it and a patient understand it.

The Eight Scenes

Eight moments.
One common thread.

Each scene captures a distinct context where HeartWise changes how people understand, communicate, and act on cardiac information from the clinic to the field, from the lecture hall to the bedside.

01

Doctor Explains to Patient

A cardiologist turns the HeartWise visualizer toward their patient. The 3D beating heart, live BPM, and synchronized EKG make a complex diagnosis legible without a single medical term.

02

Teaching Medical Students

In a lecture theatre, the heart is projected at scale. Chambers, valves, and coronary arteries are labelled in real time as the lecturer walks students through every beat of a PQRST cycle.

03

Students Practise Independently

The same simulation runs on a student's laptop after midnight. They rotate the heart, toggle labels, and answer practice questions learning at their own pace, on their own time.

04

Remote Telemedicine

A specialist in one country reads an ECG streaming from a clinic thousands of kilometres away. The same waveform draws on two screens in the same heartbeat, making distance irrelevant.

05

Smartwatch AFib Detection

A rhythm stutters on a wrist in a crowd. Before the wearer has sat down, their cardiologist has the trace, the MI cue has fired, and emergency services are on standby.

06

Post-Surgical Recovery

Day fourteen after bypass surgery. A patient reads in their chair while HeartWise quietly monitors their pulse and surfaces any change worth reporting calm, continuous, unobtrusive.

07

Developing Countries Access

A community health worker in a region without echocardiography holds HeartWise on a phone. The same diagnostic capability available in a city hospital now fits in a palm in a rural clinic.

08

Anxiety and Panic Monitoring

At 3 a.m., a chaotic waveform on screen steadies as a person breathes through a panic attack. HeartWise does not fix the fear it shows them they are already regaining control.

Storyboard

Eight scenes. Eight lives.
One visualization.

This animated storyboard traces all eight use cases from the exam room and lecture hall to the rural clinic and 3 a.m. bedside showing how HeartWise fits every context where cardiac understanding matters.

Why It Works

Simple. Visual.
Privacy-preserving.

HeartWise works not because it is the most technically complex solution, but because it is precisely matched to what a non-clinical user actually needs in a moment of uncertainty.

Visual First

A live EKG waveform makes the abstract BPM number tangible. You see the rhythm, not just the count.

Color-Coded Zones

Blue, Green, Orange and Red zone indicators give instant, pre-attentive understanding without reading a word.

No Data, No Risk

HeartWise requires no login, no health records, and no backend. Patient privacy is preserved by design.

Plain Language

All explanations are written for a general audience: calm, clear, and free of medical jargon.

Instant Response

Every change in BPM updates the waveform and interpretation in real time. No loading, no friction.

Supports, Not Replaces, Clinicians

HeartWise is explicit that it is educational. It guides users toward clinical care, not away from it.

Devil's Advocate

What could go wrong
and how we address it

Honest design requires confronting failure modes. Here are the two primary risks and our mitigation approach for each.

Risk 01

Overtrust & Self-Diagnosis

Users may treat HeartWise as a medical authority and delay seeking urgent care. To address this, the interface clearly labels itself as an educational prototype and prominently states that symptoms, not numbers alone, determine urgency.

Mitigation 01

Calm Language and Clear Disclaimers

Every elevated or critical zone display is accompanied by plain-language context and a reminder to seek clinical care for symptoms. The app guides. It does not diagnose.

Risk 02

Color Zones Increase Anxiety

Seeing an orange "Elevated" or red "Critical" badge could alarm users rather than inform them, especially those already anxious about cardiac symptoms.

Mitigation 02

Context Over Color

Each color zone is paired with practical next steps written in a calm, empowering tone. "Your heart rate is elevated. This can happen after activity, stress, or caffeine. Monitor for symptoms and contact your doctor if concerned."

Why Not Just a Static Chart?

A simpler solution, a static heart rate reference chart, would list bradycardia, normal, elevated, and critical ranges. But it cannot show how BPM affects the waveform rhythm, making it less engaging and less intuitive. HeartWise keeps the solution simple while making the information interactive, visual, and personally meaningful. The added complexity of an animated waveform is justified because static charts fail to build the conceptual bridge between a number and a lived cardiac experience.

Design Disclaimer: HeartWise is an educational prototype and does not provide medical diagnosis. Users should seek urgent care if they experience severe or worsening symptoms such as chest pain, fainting, severe shortness of breath, or sudden weakness. Heart rate numbers alone are not sufficient to determine the severity of a cardiac event.
