First interrogation and revision in two weeks

My report showed no events so I can't say if it keeps track of rate drops or not. 
 

I am sure it's a relief to know that very soon your lead will be repositioned and stop being in such a strange place. Hope everything goes smoothly and to your comfort!

I also have a rate drop setting, and it has been a life saver for me. Before they added this feature I would have weird de jevu type episodes that were not pleasant. i am now on my third pacemaker. My last one would report >9,999 episodes. Since my new pacemaker the setting has been changed to a drop size of 25bpm(I'm not sure over what time) (before it was a drop size of i think about 10bpm), and I now record a finite number of about 8,000 events. So it also depends on what your rate drop setting is.

Another setting to look up.

I’m assuming a rate drop event is an unexpected drop in BPM compared to the “normal”.

The device probably has some sort of signal processing going on that smoothes or averages the raw signals detected so that the device isn’t reacting to every small change. A typical smoothing process is a rolling average where the number of readings in the average determine the sensitivity.

A boiler in a heating system has to have some smoothing built in or it would be switching on and off too frequently.

Another way to avoid over sensitivity is through hysteresis or dead band where small changes are ignored.

I’m guessing that these rate drops are not going through the generator base rate as this would indicate something else going on, but rather something out of the ordinary. You might have an average running at 80-BPM that suddenly gets a reading of 60-BPM. A drop of 20-BPM would be significant.

Yes, the technology increases at a rate of knots. An improvement in one component very quickly trickles down to pacemakers.

It’s often said that the moon landings had less computing power on board that a mobile phone. Probably an exaggeration as mobile phones are quite powerful. It also depends on how much you expect it to do.

The key component, the controller, is the item that does increase in power and capability all the time. A million calculations a second are commonplace and the type of calculation can get more complex.

A typical computer running 64 bit Windows can handle numbers up to about 2 with 20 following zeros, or 2 times 2 done 64 times.

Memory size increases as well. The number >254 events caught my eye. 256 is a significant computer number. It’s an 8-bit number and sets the maximum number that a memory location can hold. Newer devices have larger memories and can store more data.
