What Causes Sinus Tachycardia?
There are several conditions that may cause it.
Detailed Answer:
Hi, I have gone through your question and understand your concerns.
Sinus tachycardia may be physiologic (that means it is a characteristic of yours) or may have several underlying causes: Anemia, Pheochromocytoma, Hyperthyroidism, Myocardial infarction, Anxiety etc.
The heart damages include thickening of heart walls and in severe cases cardiac insufficiency.
Treatment consists on treating underlying causes. Beta-blockers help in some cases. In the pre-operative period the anesthetist will also do a complete check up and will be prepared and aware of your cardiac health. Please talk to him about this too. If the Echo shows something, I am sure they will deal with it and then only proceed with surgery.
If no underlying causes, ( or physiological) generally there's no need for treatment.
If you didn't had previously health issues related to tachycardia ( fatigue, fainting, shortness of breath), then you have nothing to worry about, your surgery will not be cancelled.
Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions.
