tachycardia AFTER echo stress test

I had a echo stress test yesterday which was "normal," they said. But there were PVC's during the test so I don't understand how that is normal?

And after the exercise portion, I lied down and did the echo part and as I was in the recovery period my heart suddenly took off and went to about 160. Then it came down to 120 and then went back up again while I was just relaxing on the table! They paged the doc and put me on oxygen and eventually sent me home but my heart was at 120 for 2 hours at home so I called cardio to ask them about it and they told me to go to the ER if I lie down and it doesn't come down soon but it eventualy did.

What could this be? Has anyone ever experienced anything like this before?

Thanks. . .

Yup. I know the heart racing off for no apparent reason all to well. Not after an echo stress test per say but after normal excersise. There is something out there called IST. If you google it you will see what I am talking about. I was given a beta blocker to keep on hand if I have a tachy espisode. I am suprised they told you to wait that long for your heart rate to return to normal. My Cardio always told me under an hour.. If not back to normal take the beta. If others symptoms with the sinus tach, go to the ER!!

Thanks for the advice! I looked up IST and in some ways it fits but in other ways I don't think it does. . .like I don't have a heart rate that is normally over 100 at rest. My heart rate is often in the 80's. Yesterday, I got tachy 2x just while sitting at the computer.

I am also having swinging blood pressure throughout the day. My spikes can reach 150's over 90's at times and then drop 10-20 minutes later to 115/72 or so. They have almost given me a beta blocker but my bp always drops out and so I have never had one yet.

I feel terrible with all the instability, almost under the weather or something...it's hard to describe but exhausted for sure.

I don't know if cardio is going to bring me back sooner than the end of the month when I have my next appt scheduled. I am on a 21 day monitor right now until then. Should I be asking for something else???

I have the exact same issue with an IST diagnosis. Some things fit some don't. It's great your on the monitor. This way if you have an attack it will show how the heart rytham starts and ends. That is a very important piece of info for your Cardio doc. Sometimes SVT can be a hidden cause.. And it can be hard to catch. But, if caught there is treatment and the approach is diff than that of IST. I would see what your monitor shows and go from there. Do you see an EP specialist? Good luck.

Report post

No, I don't see an EP specialist but my cardio doc was paged while this was happening and he said he may be referring me to one but then he deferred to the doc in the office to look at the test right then. And he looked at the echo and told the nurse to tell me, "there are no blockages and you're on a monitor so let's wait and gather more info. . ."

Hey tackyinCA,

"like I don't have a heart rate that is normally over 100 at rest. My heart rate is often in the 80's. Yesterday, I got tachy 2x just while sitting at the computer"

I'm sitting here with an ice wrap on my head...from the migraine induced by the nitro tab I had to pop this morning....waaaaah : ) This is to alert you in case I say something that doesn't make sense.

If you are experiencing atrial chamber tachycardia (the upper chambers), the numbers can run high pretty fast. The upper chambers are paced by the sinus nerve branch and beat faster than the ventrical chamber (lower) pacing. Also, the left and right sides of the heart are paced via separate but normally synchronized bundle branch node lines that carry current throughout the heart cells. Atrial 'flutter' or tach that last too long may indicate a slight synchronization irregularity between the sides of the heart.....It can be quickly resyched at a hospital for you. The danger of a-tach is probability of stroke from not enough blood-oxygen getting to brain regularly enough.

Have you been advised to take some form of blood thinner like baby aspirin? If this is your first experience with this a-tach, I wouldn't hesitate to visit the ER if you can't get a quick appointment with a cardio.

Hang in there....I know how distressing and literally nauseating this feels to you.

Let us know how it is going....

Thank you for the great info. . .this is my second experience with a-tach I now realize. In March, I had what I thought was an adverse drug reaction to sulfa which sent me into runs of tachycardia for a couple of hours and then my heart stayed over 100 for over 48 hours but I had no idea that it was dangerous until now.

Will they be able to tell from the monitor what kind of tachycardia it is? (atrial or ventrical) I only have 2 leads and they said "it's just an EKG. .. "

When I get tachy at this point, it lasts less than a minute and my heart is at a normal pace now so I shouldn't need help to synchronize it, right? That was just for when it lasts too long??

Thanks again!

Could be mitral valve prolapse. That causes those symptoms. They'll hear it on a stethoscope, a clicking sound, and then confirm it with an echocardiogram. Did they mention if they saw it on your test?

Report post

Hi Susie,

They said my regular echocardiogram was normal that I had last week and then this stress test one too. So except for the PVC's during and the tachy issue after test, I guess it couldn't be that then, right?

I walked up one flight of stairs and got tachy to about 160 today just for about a minute but the monitor people said it wasn't high enough to call the doc. . .I guess it has to be 175 or something to be an "emergency" but if I had walked up one more flight it would have been.

Report post

Tachyinca. Do you mean it your heart rate is real high for less than a minute? Like it starts suddenly then stops suddenly? If that is the case .. That may be SVT. The reason I ask you that.. Is because that question was asked of me many times by my EP Cardio when questioning SVT.

Report post

yes! so I walk up 1 flight of stairs and then after I am done, my heart rate shoots way up very very fast and then slows down pretty quicky--all in about the course of a minute.

Report post

Hmmmm. Tell your doc about that. Does it happen every day? My hr after walking up the stairs can be high and then slows down. I just tend to get these racing episodes where my heart will race off to like 130 ish and stay there for like 30 to 40 minutes. Happens out of the blue about every 3 months. So odd. I wish us both luck here. Lol.

thank you martzi for explaining,.....
