Hello doctor,

I was having palpitations so I had conducted an ECG. I now need to interpret the ECG reports. Kindly suggest.



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 out 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 or anemia or both). If there is chest pain associated with exertion then cardiac evaluation can be done. If this happened only once without any other symptoms as such there are no alarming changes in ECG, then there is nothing to worry. Consult a physician in person if needed. Thank you.

Hello doctor,

Does the ECG show a prolonged QT wave? I was told the machine said it does. Kindly help.



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. Thank you.
