How to manage supraventricular tachycardia?

Question

Hello doctor,

I am a 24-year-old female. My resting heart rate is in the 70s when sitting, but it jumps to 120 to 130 beats per minute when I stand. Doing dishes raises it to the 160s. I tend to black out for a few seconds when I stand up. I have fainted five or more times. My doctor performed an electrocardiogram (ECG), and my follow-up appointment is not for a few weeks. The notes on the ECG indicate the following interpretations: sinus tachycardia, right atrial overload, P > 0.25 mV in lead II aVF, P duration = 93 ms, vertical axis, probable lateral infarct, R < 0.15 mV in V6, and RSR in V1 and V2. Can you please interpret this for me?

Hello,

Welcome to icliniq.com.

Your ECG (electrocardiogram) shows that your heart has enlarged and exhibits signs of SVT (supraventricular tachycardia). SVT is caused by a defect in the transmission of electrical activity from the upper chambers of your heart to the lower chambers. When your heart beats rapidly, it does not have enough time to pump blood effectively, which is why you experience episodes of fainting. You need to undergo an echocardiogram and a chest X-ray to rule out other causes. SVTs are generally not life-threatening. Please continue taking your medication.

Best regards.
