Sinus Rhythm with Wide QRS Kardia flagged my most recent ekg as Sinus Rhythm with Wide QRS. I've attached it here. It's the first time I've seen the Kardia say this. I've had tachycardia, unclassified and afib over the last couple of weeks but this is the first Sinus Rhythm with Wide QRS. Is there any reason to be concerned about this? My rate was 99 during this ekg, so I'm wondering if it were 1 or so beats higher at 100+ if it would of just said Tachycardia? I don't think there is a tachycardia With wide QRS? I don't know if Amiodarone can cause a wide QRS? I am 3 weeks out of surgery and I've had the Kardia tell me just about everything except Bradycardia. I know the heart can do erratic things in the blanking period but being this is the first time I've seen NSR with Wide QRS I figured it can't hurt to ask If this should be a concern. https://www.afibbers.org/forum/read.php?9,195310,195310#msg-195310 Wed, 08 Apr 2026 04:14:55 +0000 Phorum 5.2.23 https://www.afibbers.org/forum/read.php?9,195310,196529#msg-196529 Re: Sinus Rhythm with Wide QRS https://www.afibbers.org/forum/read.php?9,195310,196529#msg-196529
My cardiologist ordered a cardiac PET scan, where the ECG showed an abnormal QRS-T angle. Possible primary T wave abnormality. PET shows one area of probable infarction. R wave axis has changed from -45 to +5 degrees (50 degrees from previous ECG in December). Changes to other timing as well.

It can be insignificant as others have stated, but not always so.]]> ColoradoKen AFIBBERS FORUM Tue, 02 Jul 2024 22:02:12 +0000 https://www.afibbers.org/forum/read.php?9,195310,195357#msg-195357 Re: Sinus Rhythm with Wide QRS https://www.afibbers.org/forum/read.php?9,195310,195357#msg-195357 McHale AFIBBERS FORUM Wed, 27 Mar 2024 18:33:10 +0000 https://www.afibbers.org/forum/read.php?9,195310,195322#msg-195322 Re: Sinus Rhythm with Wide QRS https://www.afibbers.org/forum/read.php?9,195310,195322#msg-195322
I've had my kardia for over a year and probably took a hand full of ekgs when I was in afib 100% of the time. Over a year and prior to my surgery I almost never took an ekg and never posted one here or anywhere. I had robotic mitral valve repair surgery and a CryoMaze procedure 3 weeks ago so I am intentionally trying to get an idea of what my ekgs look like during the blanking period.

The first week I was in NSR 100% of the time. The second week I had some arrythmias and a much higher heart rate. My metoprolol was increased to 100mg total at 50mg twice a day and since the increase my average resting heart rate is around 85bpm. However, I am typically in tachycardia or possible flutter most of the time.

No matter whether it's afib, flutter, tachycardia or sinus rhythm I have no symptoms at all. No dizziness or fatigue or shortness of breath. I don't even feel my heart beat AT ALL. I feel very fortunate to be asymptomatic. I can't tell flutter from NSR from tachycardia at all. I have no symptoms with any of it. I just know to get my EF increased I likely need to be in NSR more often than not so I have been much more focused on my ekgs during this blanking period.

With that said though I agree at this point over three weeks as crazy as all the different ekgs have been it's to be expected during the healing process so I'll wait until the 60 day plus window and just hope I'm in NSR routinely.]]> cornerbax AFIBBERS FORUM Sun, 24 Mar 2024 03:41:48 +0000 https://www.afibbers.org/forum/read.php?9,195310,195321#msg-195321 Re: Sinus Rhythm with Wide QRS https://www.afibbers.org/forum/read.php?9,195310,195321#msg-195321 Carey AFIBBERS FORUM Sun, 24 Mar 2024 03:35:27 +0000 https://www.afibbers.org/forum/read.php?9,195310,195320#msg-195320 Re: Sinus Rhythm with Wide QRS https://www.afibbers.org/forum/read.php?9,195310,195320#msg-195320 calvin AFIBBERS FORUM Sun, 24 Mar 2024 01:44:01 +0000 https://www.afibbers.org/forum/read.php?9,195310,195318#msg-195318 Re: Sinus Rhythm with Wide QRS https://www.afibbers.org/forum/read.php?9,195310,195318#msg-195318
In this case I was sitting at a table very still and didn't move at all. I don't think there is much or any noise/static in the EKG?
Being that flecainide caused a wide QRS for you I wonder If amiodarone is doing the same. Carey mentioned it isn't wide enough to be of concern and I'll see what the EKGs over the next few weeks look like.

@Joe,

Thank you for your response I'm not sure what any of that means though.]]> cornerbax AFIBBERS FORUM Sat, 23 Mar 2024 22:58:03 +0000 https://www.afibbers.org/forum/read.php?9,195310,195317#msg-195317 Re: Sinus Rhythm with Wide QRS https://www.afibbers.org/forum/read.php?9,195310,195317#msg-195317

Does amiodarone affect QRS duration?
Amiodarone's effect on QRS duration is between that of the IB and IA agents consistent with its tau rec of 1.5 seconds. Moricizine's effects on QRS duration are more marked than would be expected from its tau rec of 2.6 seconds but may be explained by the slow onset of inactivation block.

I will see what Kardia says later tonight and over the next few weeks but even if I were in NSR my rate is much higher then it was the first week post surgery and I'm essentially on the same medications. My rate in NSR was right at 60bpm and now it's almost always in the mid 80s to low 100s no matter what. I haven't seen a rate in the 60s in two solid weeks regardless of what classification the Kardia has so something changed from week 1 to the last two weeks to increase my rate over 20bpm. For the first full week post surgery I was in NSR every time I checked and my rate was right around 60bpm. The last 2 weeks whether it's flutter or NSR or afib or tachycardia or Sinus rhythm with wide QRS the rate hasn't been under 80 once and averages 85bpm.

85bpm is still alright but as mentioned, something changed from week 1 to week 3 to increase my rate 20-30+bpm regardless of what classification Kardia gives.]]> cornerbax AFIBBERS FORUM Sat, 23 Mar 2024 22:11:43 +0000 https://www.afibbers.org/forum/read.php?9,195310,195314#msg-195314 Re: Sinus Rhythm with Wide QRS https://www.afibbers.org/forum/read.php?9,195310,195314#msg-195314 GeorgeN AFIBBERS FORUM Sat, 23 Mar 2024 21:45:28 +0000 https://www.afibbers.org/forum/read.php?9,195310,195313#msg-195313 Re: Sinus Rhythm with Wide QRS https://www.afibbers.org/forum/read.php?9,195310,195313#msg-195313 Carey AFIBBERS FORUM Sat, 23 Mar 2024 21:20:57 +0000 https://www.afibbers.org/forum/read.php?9,195310,195312#msg-195312 Re: Sinus Rhythm with Wide QRS https://www.afibbers.org/forum/read.php?9,195310,195312#msg-195312 cornerbax AFIBBERS FORUM Sat, 23 Mar 2024 21:18:55 +0000 https://www.afibbers.org/forum/read.php?9,195310,195311#msg-195311 Re: Sinus Rhythm with Wide QRS https://www.afibbers.org/forum/read.php?9,195310,195311#msg-195311 gloaming AFIBBERS FORUM Sat, 23 Mar 2024 20:53:30 +0000 https://www.afibbers.org/forum/read.php?9,195310,195310#msg-195310 Sinus Rhythm with Wide QRS https://www.afibbers.org/forum/read.php?9,195310,195310#msg-195310
