Usage

• 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.

Details

• 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

Upcoming Features

• 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.
