I'm not a doctor. Been a WebMD member since August 1999.
"I have been told I have inappropriate sinus tachycardia"
I have IST (am under the care of an interventional cardiologist/electrophysiologist) too, though not 100% of the time.
"I've seen people post that ablation therapy wasn't very helpful."
This is true.
In my specific case/situation, I wouldn't even consider anything as drastic/risky as undergoing a cardiac ablation. Good general info -
Inappropriate sinus tachycardia (IST)
A misunderstood cardiac arrhythmia
IST is a condition in which an individual's resting heart rate is abnormally high (greater than 100 beats per minute)......
SEE: Page 2 Treating IST
Part 2: Treatment options for IST
Drug Therapy For IST
In many patients with inappropriate sinus tachycardia (IST) drug therapy can be reasonably effective. But achieving optimal results often requires trial-and-error attempts with several medications, singly or in combination.
Non-Drug Therapy For IST
Sinus node ablation has so far achieved only limited success. While this procedure can eliminate IST in up to 80% of patients immediately after sinus node ablation, the IST recurs within a few months in the large majority of these patients.
Waiting. One reasonable non-pharmacologic approach to managing IST is to do nothing......
Increase in resting heart rate is a signal worth watching
Many factors influence resting heart rate. Genes play a role. Aging tends to speed it up. Regular exercise tends to slow it down.......Stress, medications, and medical conditions also influence the heart rate.
Tighten stomach muscles. As soon as the heart starts to race, tighten the stomach muscles. This will cause the abdominal muscles to put pressure on a group of nerves that will tell the heart's electrical coduction system to slow down.
Chill. Take a deep, long breath and slowly let it out. Sometimes relaxation is all it takes to stop tachycardia. And deep breathing is frequently one of the fastest ways to relax.
Use common sense. Anything that speeds up the heart, caffeine and cigarettes, for example, can trigger a rapid heartbeat. So common sense says that if one is prone to tachycardia, one should avoid any substance that might give the heart an extra kick.

This Makes Your Heart Attack Risk 8 Times Higher A new study links high levels of anger to an increased risk for heart attack
Having an episode of intense anger was associated with an 8.5 times greater risk of having a heart attack during the following two hours, a new study published in The European Heart Journal Acute Cardiovascular Care showed. The new findings add to prior research that has suggested high levels of anger may spur a heart attack.
The study is small and therefore it's still too early to know how great of a factor intense anger is in predicting heart attack onset. The anger levels are also self-reported and could differ person to person...... View Thread
There is stress cardiomypathy or Broken-Heart Syndrome, a condition that closely mimics a heart attack.
L@@K back in the media
Just about all of us have had our hearts broken at one time or another. Now, researchers from Johns Hopkins have discovered severe grief can cause a real medical condition that looks much like a heart attack, and is often misdiagnosed.
Emotional stress causes an unusual type of heart disease
Being 'broken-hearted' as a result of emotional trauma may be a more apposite turn of phrase than we imagined. US researchers have shown how sudden emotional stress can release hormones that stun the heart into submission, resulting in symptoms that mimic a typical heart attack.
People suffering from stress cardiomyopathy, or 'broken-heart syndrome', seem to be having a heart attack:....../though the heart muscle is weakened, it is not killed, or infarcted, as in a classic attack.
I'm reminded of a 2006 episode of ER (NBC TV), there was a scene in which a woman was hit (collapsed to the floor) with stress cardiomyopathy as she had just learned from Dr. Rasgotra (Neela) that her husband had died after surgery.
Neela didn't give up and saved the woman's life, to everyone's (who was in attendance) amazement. Very dramatic, and of course, happens in real life.
Researchers are now using three-dimensional, or 3D printing to create models of the human heart to help heart specialists. The heart doctors can use the models to better help patients before an operation. Surgeons regularly use digital images to explore the heart in close detail. But no two human hearts are alike......
