Create Retriggerable Timer for Relational Pulse Monitoring

[Pcorcs]

Introduction:

The following example demonstrates a method for retriggering a timer to monitor information about relational pulses. One application of this algorithm is outlined below:

The example is designed to monitor pulse registered in 2 data streams: atrial and ventricular rhythms. The code monitors for discrete timing delay in the registration an atrial beat with respect to the next closest ventricular pulse. If arrhythmia symptoms exist, there may be a timing delay between atrial and ventricular beats. The code will set a flag when this condition occurs, providing the end-user diagnostic information. There are multiple timing scenarios associated with prescribing an ablation procedure.

Steps to Complete:

1. The code structure utilizes parallel loops with notified synchronization to assert pulses registered in the acquisition loop.

2. When atrial beats are registered, they are passed to the Timing Detection Loop to begin clocking various ventricular delays.

3. If a ventricular beat is registered before a symptom clock expires, the operation is aborted; and, the program waits for the next atrial pulse.

4. If no ventricular pulse is detected within the specified symptom time, a flag is raised and the application is stopped.
