## Description

This App is useful  to know of your stroke risk, by recording of your heart rhythm on the graph. 

With our passion that we want to reduce cardiogenic cerebral embolism (CCE) as many as possible, we developed this app.

The major cause of CCE is atrial fibrillation (Af).  There are the established means of prevention and care before CCE onset.

However, the problem is that Af is often without symptoms or a little symptom; therefore, few patients undergoes appropriate treatment.
We wish more and more patients with Af are undergoing  appropriate treatment as many as possible with the use of this app.

How to use this App.
*Record your heart rhythm by iPhone camera and check your stroke risk. 

　Please place your tip of index or middle finger on the camera lens.
　Keep your fingertips relax and not to move while monitoring heart rhythm.
　Screen shot of your heart rhythm is taken when the heart rhythm graph is stabilized, 
　and you can check of your stroke risk by comparing your pulse record against 
　irregular pulse record. 

　If irregular intervals were observed, please consult with a primary-care doctor.
　Normal pulse ( called sinus rhythm ) is made by regular contraction of heart. 
　In contrast, arrhythmia cased by atrial fibrillation (AF) is made by irregular contraction 
　of heart. 

*Know the mechanism of the Stroke and calculate the risk for an onset of Stroke.

　Atrial fibrillation (Af) is a very common arrhythmia.    Prevalence of Af is increasing as aging. 
　This is reported that some 50s may have Af, 10 percent of 80s have Af. 

　Af promotes blood clotting ( thrombus ) in heart.
　Thrombus in heart sometimes blocks suddenly cerebrovascular on blood flow. 
　This is called the cardiogenic cerebral embolism (CCE). 
　CCE is one type of severe stroke that has high fatality rate. If survival, CCE patient 
　often has serious sequela.

　Af is the most critical risk of CCE. Fortunately, now we have established means of 
　prevention and cure of Af and CCE if finding Af before the onset.
　Prevention is better than cure. The most important thing is early diagnosis and early 
　consult to the appropriate hospital.

　Calculate the risk using CHA2DS2-VASc Score, and you will know your  annual risk rate
　and lifetime risk rate of developing CCE..

## Review summary

User reviews show Heart\_Rhythm as a free, innovative tool for a general rhythm snapshot without diagnosis, but reliability and usability issues dominate: inconsistent readings, frequent crashes, device/OS compatibility problems, and a clunky UI that hampers effective use.

### Pros

- Provides a general rhythm screening snapshot without diagnosing.
- Free to use.
- Seen as an innovative, forward‑looking approach to rhythm monitoring.

### Cons

- Unreliable/erratic readings and misclassifications (e.g., AFib mislabeling, very high/low heart rate readings).
- Frequent crashes or sudden shutdowns when starting or using the rhythm checker.
- Compatibility issues across devices/OS versions (not working on some newer iPhones or older iOS).
- UI/UX and usability problems (incomplete checklists, confusing prompts, layout issues).
