Hello doctor,

I am a 24-year-old female. I have a resting heart rate in the 70's when sitting, but it jumps to 120 to 130 beats per minute when I stand. Doing dishes gets me to 160's. I tend to black out when I stand up for a few seconds. I have fainted five or more times. My doctor performed an electrocardiogram, and my follow-up is not for a few weeks. The notes on the ECG read as follows. The interpretations are sinus tachycardia, right atrial overload, P > 0.25 mV in ll aVF, P = 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?



Welcome to

Your ECG (electrocardiogram) shows that your heart has enlarged and has signs of SVT (supraventricular tachycardia). SVT is caused by a defect in transmitting electrical activity from the top of your heart to the bottom. When your heart beats fast, it does not have enough time to pump out blood. That is why you have episodes of fainting. You need to go for an echocardiogram and a chest X-ray to rule out others causes. SVTs are not life-threatening. Keep up with your medication. Best regards.
