What are non-specific ST wave changes?

Hello,

Welcome to icliniq.com.

According to ECG (electrocardiogram) reports (attachment removed to protect the patient's identity) - sinus tachycardia and nonspecific ST wave changes. Explanation - Heart rate is more than 100 (approximately 115 bpm), and because of the high rate, there are some nonspecific changes. So, the cause of increased heart rate should be found and treated accordingly. It can be idiopathic sinus tachycardia (without any reason) or secondary to other conditions. Possible causes - anemia, anxiety, stress, dehydration, excess blood loss (may be seen during periods), hyperthyroidism, or heart disease. Advice - Get some blood tests if it continues. Hemoglobin test (for anemia), TSH (thyroid stimulating hormone) test for thyroid. Monitor blood pressure (lower blood pressure may suggest dehydration, anemia, or both). If there is chest pain associated with exertion, then a cardiac evaluation can be performed. If this happened only once without any other symptoms, as such, there are no alarming changes in ECG, then there is nothing to worry about. Consult a physician in person if needed.

Hello,

Welcome back to icliniq.com.

For heart rates above 100 bpm, we should use Framingham or Fridericia formula for corrected QT (QTc) wave. Your QTc is normal according to the formula.
