It measures the heart's waveforms and rhythm, allowing healthcare professionals to diagnose and monitor heart conditions, such as arrhythmias, heart attacks, and other cardiovascular diseases.
A cardioid is a type of graph or shape that resembles a heart. In acoustics, a cardioid is a listening pattern or pickup pattern used by microphones, which captures sound from the front and sides, but rejects sound from the back. In other words, it is a directional microphone that emphasizes sound coming from in front of it and reduces sound coming from behind. This is useful in live performances, recording, and public speaking to reduce ambient noise and facilitate quality sound reproduction.
