Below is an instruction that describes a task. Write a response that appropriately completes the request. ### Instruction: 40M, 5'10", 210 lbs, Caucasian, California.5mg Bisoprolol for arrhythmia, 160mg fenofibrate for high trigs, 300mg gapapentin for chronic thoracic spinal painHello. I'll try to keep this as short as possible as I know you're all busy.TL:DR - https://imgur.com/a/m5lprmBWondering if anyone can offer an opinion on this ECG from my implanted loop recorder. The loop recorder was inserted 1.5 years ago to investigate a an episode of sustained arrhythmia + syncope. I have a history of AVRT (ablated in 2006, possibly WPW, but that wasn't made fully clear to me). It seems something didn't go quite right during the ablation and the AVRT was eliminated but I developed frequent PVCs that were not present before the procedure. I have some documented NSVT from holter monitors and 30 day loop recorders over the past 10 years.My loop recorder seems to not be programmed to detect much of anything on its own. I think I would have to literally be in v-fib for it to automatically flag an event for review. After about a year of it literally capturing nothing despite having symptoms, I requested a patient trigger device that I can use to force the device to record and upload an event. Since I have started using the trigger, I have been able to capture several episodes such as this: https://imgur.com/a/m5lprmBWhen I look at this, my untrained sees a salvo of PVCs, which I guess technically defines NSVT. I have asked my doctor for an opinion on these events and every time his response is basically "Doesn't look like anything to me".What he doesn't seem to understand or appreciate is I find these episodes to be physically very uncomfortable and honestly, highly distressing, like hand over heart, feeling like I'm going to die sort of vibes. I admit that's probably a bit dramatic and an overreaction, but my cardiac history and long road to a diagnosis has trained me to think this way. Additionally, I am dealing with Kaiser Permanente in California and unfortunately, they have a rather abysmal reputation for cardiology and electrophysiology is basically non-existent.I realize there's people out there that have PVCs and other palpitations and barely notice them, but for some reason when I experience them, its like I'm getting punched in the chest.My hope is that someone out there can give me a reason why I should NOT be worried about these events. My doctor seems to be very, very, unconcerned by them, and maybe he's right to think that, but an explanation would be nice and if there's a way to be less frightened by these episodes, I think that should be considered therapeutic and part of the plan for care in this situation.Thanks for reading.. ### Response: So first things first I dont see clear P waves and you seem to be slightly irregular. Do you have a history of AFib? Secondly the beats that you point out are wide but also irregular. This makes it less likely that they are PVCs/NSVT and more likely to be AFib with aberrant conduction if you have AFib to begin with. Since you have AVRT and have had ablation, its not unusual to have some aberrancy when the rate changes since you have an abnormal electrical conduction system thats also been burned. While this isnt life threatening in any way, increasing your bisoprolol dose would probably help keep the rates better controlled and decrease your symptoms. You can also get a cardioversion/ablation if you are actually in AFib.
