Tachycardia with Mild Exercise

Can someone please tell me why with old mild exercise I am experiencing tachycardia?  I just bought a heart monitor.  I have had an EKG, Echo and Echo Stress Test and still no determination has been made why my heart is doing this.  I do not get tired, no pain or short or breath?  I feel frightened with this unusual thing happening.  When I had the 24 hour halter last week (did not go to gym) there was no abnormalities.
I would be so grateful if someone could tell me what is wrong with me.  Thanks so very much.

I think you need to supply some more info. age, what was the heartrate you describe, whats your blood pressure, how's your weight, any diabetes? etc

Did you experience tachy during the stress test?

My guess - you have some brand of SVT.
My second guess - it's probably not a fatal arrythmia.

My first suggestion - get an EVENT monitor.
Does this happen every time you exercise? Once a week?

I had this problem and it was not a problem... until it was a problem (sent me to the ER twice in 2 mos).  I'm ablated and fixed over a year. I have well over 1000 (running) miles on the "new heart."

Let's assume that you are indeed having Supra Ventricular Tachycardia episode (please understand that we have no way of knowing).  SVT can be initiated at any time; not just by exercise.  In fact, as I aged, my lifelong SVT happened more while at rest than under heavy physical demands.  As a kid running, skating, and cycling were the kind of activities that would get it going.  As I got older, I would experience SVT driving my car, eating a meal, or perhaps just watching television.

As littlegreenman1 suggested, what you need is an "Event Monitor".  The recording period of a Holter is typically too brief to catch an event.  Also, the complexity with regards to the leads of leads isn't necessary to catch and record SVT.  A 30 day event monitor uses 2 leads attached to user replaceable electrodes.  Typically, each morning after showering, the pads are replaced and the unit is worn both awake and asleep only being removed for showering the following day.  The unit can be set to auto record cardiac anomolies as well as user triggered events.  The recording is a continuous loop, meaning it's always recording your heartbeat. If nothing is detected, the recorder eventually loops over the recorded data.  When an event is triggered, the recorder jumps back a preset amount of time in the loop and commits a certain amount of time of the recording to a memory slot.  Thee are typically 3 memory slots.  When the slots are filled, the user calls a phone number, and literally plays the recording over the phone to the a monitoring lab which conforms receipt of the recording, and allow the user to clear the memories opening them up for more events.  The duration of the 30 day monitor allows the patient a greater chance of catching an event.  

The event monitor is a necessary step in the path to either drug therapy or ablation therapy.  I too had an ablation and (hopefully) cured 54 years of SVT.  I am once again as active as 60 year old can be, running, cycling, as well as ice and inline skating.  This winter, I plan to try cross country snow shoeing. which is fun to watch and a blast to participate in.  These are all things which SVT cut into during my younger years. You didn't say how old you are, but I hope you can get control of it, bring it to a successful resolution, and not let it interfere with your life as it did mine.

Thanks for all of your answers.  I am a 64 year old diabetic female.  I am heavy unfortunately and high hypertension.  The Cardiologist immediately put me on Coreg CG.  I take two other blood pressure medicines.  

Maybe you are right and it is an SVT.  I am going to the gym tomorrow for the first time since I had the episode and I am frightened.  I have a follow-up with the cardio in 4 months.  Perhaps I should ask him about the 30 day monitor at that time.

I appreciate your time and consideration.

Thanks so Much.

I think you need to specify this a bit more.

Some important questions:

1) How rapid is the heart rate? At what level of exercise?
2) Does this rhythm start and stop instantly (like heart rate 100 up to 200 in a heartbeat, down to 100 again instantly)?
3) Is the heart rhythm regular?
4) Is the rapid heart rate preceded by premature (double or skipped) heartbeats?
5) Are you feeling dizzy or unwell? (it's good that you don't feel pain or shortness of breath)

To make some suggestions:

If the heart rate is moderately increased, regular and increases gradually, it may be a normal rhythm, just too rapid, caused by a lowered blood pressure, deconditioning, dehydration or other normal (and some abnormal) causes.

If it starts and stops instantly, and you don't feel seriously unwell, diagnosis is very likely to be paroxysmal SVT (as described by Tom).

If the heart rhythm is rapid and irregular, the diagnosis is probably atrial fibrillation.

Both atrial fibrillation and SVT are often preceded by a slightly irregular heart rhythm (PACs) though they don't necessarily have to be.

Take care.

I am a healthy 26 yr old female also suffering from tachycardia on mild exertion (close to 200 bmp while carring a laundry basket up 7 stairs) I used to ski and play soccer and am at my witts end. All my scans have been normal. I am also experiencing muscle weakness. I don't have an arrythmia, but it gets going so fast, just from standing up sometimes. They checked me for POTS, but said my BP went UP not DOWN when verticle...so said it doesnt fit. Has anyone else experienced this? it's been happening since Dec 2011.

See my post above... same thing.

I used to get it once a month... every other week...
Stand up too fast... bend over... boom! Heart rate through the roof. Generally I could just sit down, relax, breathe and it went away.
That went on for years.

I turned 40 and fat...started running again and that cardio had me popping several times a week.

SVT generally has little correlation to do with your pulmonary health. The pumps and cholesterol and valves are all jobs for the plumbers and carpenters. You need an Electrophysiologist.

I've never truly contributed much to the internet as far as helping others while I've benefited by the information and reviews provided by others for years. However, after testing it for the last three years, I can safely and sincerely attest that I've successfully controlled my SVT with Life Extension's Super Omega-3s. I take two capsules in the morning after breakfast and two at night after dinner. I don't work for Life Extension or sell their product. I've been taking Omega-3s from other companies since 2003 after reading a medical report that claimed that these oils are stored in the heart muscle membranes in order to prevent abnormal heart rhythms. All the other brands were unsuccessful in preventing my supra-ventricular tachycardia except for Life Extension's. I've told my cardiologist to spread the word. I hope this helps anyone out there who might be suffering from these scary and stressful palpitations.
