It is not so much a kit as it is highly over-engineered LEDs, but I hope you enjoy them anyway! The program will be loaded onto the eeprom for you, but you are more than welcome to use a propplug, provided by Parallax, Inc., to reprogram the Propeller chip with whatever program you would like!
The SA, AV, and Bundle Branches are simulated in this wearable heart. The timing is accurate to the actual rhythms as well.
Normal Sinus Rhythm
Sinus Rhythm with a 1st degree atrioventricular block
Sinus Rhythm with a 2nd degree atrioventricular block Type 1
Sinus Rhythm with a 2nd degree atrioventricular block Type 2
Third degree atrioventricular block
Sinus Rhythm with a Bundle Branch Block
Normal Sinus Rhythm with Pre Atrial Contractionis
Normal Sinus Rhythm with Pre Ventricular Contractions
Off (Propeller still on)
