Hi Steve,
Send me your number and we can discuss more details and nuances of this change. It may well be a burst of sinus tachycardia from a myriad of possible proximal causes but not necessarily an actual arrhythmia that might otherwise inspire a call into your NP at Dr Natale's office in Austin.
Let's try to sort out what exactly this elevated HR is and then go from there. After 5 years of total post index ABL success with Dr. Natale, it would be a very remote chance of this being an arrhythmia recurrence due to a reconnection of any previously ablated trigger source. So if it is the harbinger of some new activity that needs addressing, the odds would very strongly be on the side of it being a new previously undetected and unablated trigger area, possibly due to it being too immature to be detectable during your 2011 index ablation, or perhaps having been supressed due to anesthesia such that Dr Natale could not identify it as a likely consistent active trigger back then .... though the later scenario is a bit less likely than the former scenario due to the long period of freedom from all atrial tachy-arrhythmias you have enjoyed after one ablation by Dr Natale.
Regardless what it turns out to be, you can take great comfort in knowing that your departure from normal sinus rhythm is only temporary and you are already in
the loop with the best possible physician to sort this out for you expeditiously, should a touch up ablation even be in the cards for you now which is not clear at all that it is from what you have shared here today.
Look forward to catching up Steve,
Shannon
