Brief Answer: SVT= SupraVentricular Tachycardia. Detailed Answer: Hello XXXX I am Dr Saumya Mittal, MD The problem with the acronyms is that one cannot be sure that they are the standard acronyms used, they vary person to person I, considering your heart rate, feel that they probably meant SupraVentricular Tachycardia. Unless they meant PSVT- Paroxysmal SupraVentricular Tachycardia. What happens is that our heart has a small generator of pulse. This keeps the heart firing. Sometimes there is another place in the heart that also starts producing the heart beat in addition to the original generator, called sinus. You may have symptoms like dizziness, dyspnea, palpitations. I would suggest you upload the ECG/ EKG. Let me know what medicines were prescribed, if any. Best of luck Dr Saumya Mittal

Brief Answer: needs further evaluation Detailed Answer: Hi again XXXX Thanks for your confidence in my response. You had not mentioned chest pain before. Where is the chest pain- which side? When does the pain occur? Any other associated symptom like breathlessness on walking, or swelling anywhere? If you had a normal ecg, stress echogram and ct chest means that a part of the investigations are normal. And that most likely your heart and chest are ok. Having said that, the fact remains that your heart rate is running at 120/m. What I am trying to explain to you now is a bit difficult to explain on net. I will try me best. The heart muscles need a constant supply of oxygen and blood. So chances are that your high heart rate is leaving the cardiac muscles deficient in oxygen. So we basically need to understand and find out why the heart rate is high. In this regard I would suggest a fasting blood sugar (FBS), thyroid stimulating hormone (TSH), Lipid profile and Vitamin D. If these are already done, I would suggest you upload the reports so I can see them along with the ECG, ECHO, and CT reports. Secondly, there are other causes of chest pain besides heart and lung. There might be a musculoskeletal cause, a severe gastritis and reflux disease and even anxiety can cause high heart rate and chest pain. Do let me know the reports on full so I can help you better And further queries and response is anticipated. Dr Saumya Mittal

Brief Answer: TSH suggest thyroid disorder Detailed Answer: Hi again. The report of lipid profile is normal. Those were also the reports of thyroid profile and Vitamin D And both are abnormal Your Vitamin D is low. I would suggest you start taking some replacement therapy And your TSH is low. This suggests that you have hyperthyroidism. This will explain your high heart rate and chest pain and anxiety. I would suggest you meet an endocrinologist to get a prescription for medicines like propylthiouracil. You may also need an ultrasound of the neck. I hope that helps. Looking forward for further queries Best of luck Dr Saumya Mittal

Could you still have hyperthyroid with normal t3 and t4
 
 
Answered by Dr. Saumya Mittal 41 minutes later
Brief Answer: can happen Detailed Answer: Hi again XXXX yes, definitely. look at the value of TSH its low because the thyroid gland is functioning fully, and possibly more than required the other possibility is that the patient is on thyroid medicine replacement but obviously you are not i strongly recommend a usg neck and a meeting with the endocrinologist. the dose of the medicine will have to be individualized and monitored hoping for further query if any best of luck Dr Saumya Mittal

Hi with normal free t3 and t4 and tsh 0.1 which would be better to take ptu or methmazole

Brief Answer: Suggest USG Thyroid Detailed Answer: Hi there Personally I would prescribe carbimazole in my patients. That should be in the same group as methimazole. However, I am not sure about the availability of this medicine in your area. I will therefore suggest meeting a local physician/endocrinologist to get you a prescription of a locally available medicines. As said before, I would suggest a ultrasound of the neck/thyroid to know why TSH is low. Some part of treatment may vary according to the usg report too. Best of luck Do feel free to ask a further query Dr Saumya Mittal

Whst are some causes that would make tsh so low? As you mentioned ultrssound of neck
 
 
Answered by Dr. Saumya Mittal 1 hour later
Brief Answer: explaining physiology Detailed Answer: Hi XXXX To answer your query I will have to tell you about the physiology and pathology of the human system. I am not sure how I will do so without using medical terms. But I will try my best. This is a coordination between two glands- thyroid gland and the pituitary gland. The pituitary gland produces TSH. This TSH acts on thyroid gland to make them produce T3 and T4. T3 and T4 act on pituitary and reduce formation of TSH; sort of counter balance phenomena So if the thyroid is producing thyroid hormones, it is likely that TSH is reduced. What we need to know is why, which is where we need the ultrasound of the neck. I hope that explains your question. Best of luck Do feel free to ask a further query Dr Saumya Mittal
