The device consists of dry electrode sensors, a comfortable chest belt, and a flexible printed circuit board (PCB). A mobile application that can receive data via Bluetooth and display an ECG graph, ...

Atrial flutter occurs when a “reentrant” circuit is present ... and has a variable appearance on ECG in regards to the flutter waves.

Case in point is a heart-monitoring IC that’s so brand new ... has been playing around with the new MAX30003 ECG chip, and the results look great. The punchline is that the four-to-five dollar ...

And because it’s also quite simple to implement the required sensors, it makes sense that electrocardiogram (ECG) machines are a popular choice among introductory medical electronics projects.

Findings on ECG include the following: a narrow complex tachycardia; and variable findings, depending on the direction of the circuit and location of the accessory conduction pathway.
