The Physiological Inbound Computer System Interface (PiCSI) was the end-product of a miniaturization project involving a hemodynamic (cath-lab) monitor project that was once shelved, and then miniaturized to fill a void in the marketplace. The healthcare consumer has become comfortable with more and more data about their own health allowing them to manage it more closely. The Apple and Samsung watches offer a mere glimpse into the human body. What was needed was something that provided more information, not just more data.
Most existing ECG devices in the consumer sphere only are capable of capturing a single lead of ECG, or at best multiple placements of a single lead ECG device to capture three leads that are mathematically augmented to six. True Multi-lead ECG is required in order to visualize multiple views of the heart waveform.
Single Lead ECG has only two connections (like a watch) and produces only “Lead One” ECG. Hospital ECG Telemetry for this reason uses a five-wire connection to produce seven leads of ECG. 12 lead ECG recording requires 10 electrode attachment. See ECG Resource Page for a broader discussion on electrocardiography and the difference between single-lead ECG acquisition devices and multiple-lead acquisition devices.
