And BTW, my AFIB episodes are OFTEN at least 4.5 hours (usually during sleep - I can only tell thanks to a cardiac App on my Apple Watch). It's never been suggested I even go the hospital when that occurs, much less have another echocardiogram! (If they did, I'd practically live there!).

In fact, my local cardio only had me go to the ER when my heartbeat recently went into constant tachycardia - at that point, for days, but it lasted for weeks before it, mysteriously, stopped. Never diagnosed.

Since as mostly reported then (during the three hour ER monitoring) sinus tacycardia - supposedly - I was just sent home to be followed up. Only, my cardio told me to go about my business including returning to the gym and not seeing me again for months (until my previously scheduled appointment.)

He didn't even change that recommendation when a week's long event monitor (my request) showed that indeed I was in tachycardia most of the time during that week. Nothing outrageous, but (not even counting brief spikes much higher) often up to 135 and certainly over 100 for almost the entire period. (In fact, the up and downness of it made the ER nurse suggest I might have "tacchy-brady syndrome" - what it sounds like.)

I feel very uncomfortable observing the widely divergent opinions and recommendations I'm getting. The Cleveland Clinic physician threw me off the most. I thought was going to be getting a state of the art overview - certainly one with which all top cardios would agree.

Not so! 🙁

Even though we have such different intervals, I remain diagnosed as having paroxysmal AFIB.
