- It detects cholesterol clogging on the heart.
- Possibility of heart attacks or past heart attacks.
- Enlargement of one side of the heart.
- Abnormal heart rhythms or dope-lope.
- Irregular heartbeat or absence of P-wave: Atrial Fibrillation
- Resting Heart Rate of more than 100: Tachyarrhythmia
- Tachyarrhythmia and delta wave: Wolf-Parkinson-White or WPW syndrome
- Sawtooth P wave: Atrial flutter
- Depression of ST-segment: it might indicate Ischemia
- Elevation of ST-segment: it might indicate myocardial Infarction
- Add a buzzer to alert the user when the heart rate is abnormal.
- Add a display to show the heart rate.
- Add a bluetooth module to send the data to a smartphone.
