Compatibility: This page is nothing but an exercise in mastering ActiveX. So, an ActiveX-enabled browser (i.e. MS IE) is needed.

Current version of the ocx control: 0.2

Get rid of older version: delete SlEcgAnalysis control from WINDOWS\Downloaded Program Files and then reload this page.

Definitions

R-spike The most prominent spike in the ECG-signal. Used to define the IBI.

IBI Inter-Beat-Interval, the time-span between two R-spikes, typically measured in Milliseconds.

HR Heart Rate, measured in BPM.

BPM Beats Per Minute: 60000 Milliseconds divided by mean IBI in Milliseconds.
