I'm experiencing moments when my pulse rate shoots up to 200 or more, and it lasts for about 4 to 5 hours. Can you help me understand why this is happening?

A pulse rate of 200 and above for 4 to 5 hours can be a sign of a serious medical condition called supraventricular tachycardia (SVT). SVT is a rapid heart rate that starts in the upper chambers of the heart. It can be caused by various factors such as stress, caffeine, alcohol, or underlying heart conditions. You should seek immediate medical attention if you experience such high and prolonged heart rates. The medication that can be used to help control SVT includes medications like Adenosine or Verapamil. The dosage and duration of treatment will be determined by a healthcare professional based on your individual case.

I got an ECG done yesterday and it shows a slight ST depression in V3. Should I be concerned about this? I've been feeling a bit uncomfortable on the extreme left side of my chest, which is why I went for the ECG in the first place. There aren't any other pains or symptoms bothering me. By the way, I took the test about 40 minutes after finishing a workout at the gym - would that have any impact on the results?

Slight ST depression on an ECG can sometimes be a normal variant, especially if you have no other symptoms. However, given your symptoms of chest discomfort and the timing of the ECG after a workout, it is important to rule out any cardiac issues. I recommend you take a low dose of Aspirin 75mg for now to prevent any clot formation and consult a cardiologist for further evaluation and management.
