AD8232 Pins

  • RA - Input 1
  • LA - Input 2
  • RL - Input 3

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.
