IST is diagnosed using tests to rule out other possible causes of tachycardia, like anemia, hyperthyroidism, and POTS. IST is treated with lifestyle changes, avoiding triggers, and medications like ivabradine and beta-blockers that lower your heart rate.
For inappropriate sinus tachycardia, treatments may include: Beta-blockers. Calcium channel blockers. Ivabradine. Catheter ablation. Cognitive-behavioral therapy. What are the side effects of treatment for inappropriate sinus tachycardia? Any medication can have side effects. Often, the benefits outweigh the risks.
Inappropriate sinus tachycardia is a condition where the heart beats faster than normal with no obvious cause. Treatments include lifestyle changes, medication, and possibly catheter...
Treatment. Your doctor may suggest a “wait and see” approach if your symptoms aren’t causing major problems. Try to avoid triggers like nicotine, alcohol, or caffeine.
Sinus tachycardia is a rhythm in which the rate of impulses arising from the sinoatrial (SA) node is elevated. Sinus tachycardia is most often a normal and physiologic response, for example during exercise. However, sinus tachycardia can in some instances be inappropriate or pathologic.
Typically, patients with inappropriate sinus tachycardia have a resting heart rate of >100 beats/minute and not explained by other causes (such as arrhythmias like Afib with RVR or sinus arrhyhthmia).
If you have sinus tachycardia with no known cause, it’s called inappropriate sinus tachycardia (IST). This can cause an inexplicably fast heart rate even while you’re resting.
Treatment of symptomatic syndrome of inappropriate sinus tachycardia is difficult, and the condition is often inadequately treated (1, 2 1). Transcatheter ablative modification of the sinus node has been proposed.
A doctor may recommend more invasive forms of treatment, such as catheter ablation, for people with inappropriate sinus tachycardia that does not respond to lifestyle changes or medication.
Although there are no evidence-based treatments for inappropriate sinus tachycardia, patients frequently benefit from obtaining a diagnosis, because it justifies their suffering and symptoms (treatment alternatives are discussed below). ECG in sinus tachycardia.
