I'm trying to understand something about ECG readings. In a normal person, when you look at the R wave in the V3 and V4 chest leads, is it due to major ventricular depolarization or septal depolarization? I could really use some help figuring this out.

In a normal person, the R wave in V3 and V4 chest leads is primarily due to major ventricular depolarization. This is a normal electrical activity of the heart during the cardiac cycle.

Question

I'm really concerned about how blood pressure might affect heart health, especially since I'm diabetic. Can you explain whether high blood pressure or low blood pressure is more likely to lead to heart failure for someone in my situation?

Question

I'm a bit worried about my TMT results that showed inducible ischemia and mentioned a 1 mm ST change in certain leads during exercise. My max heart rate reached 206, with a maximum blood pressure of 18580, and I'm only 33 years old. I exercised for a total of 6 minutes and 19 seconds, reaching a workload of 7.40 METS, but the test was stopped when I hit my max heart rate. My 2D Echo came back normal. Do you think I need to get an angiogram, or is there anything else I should consider?

Question

I've been noticing that every time I check my pulse rate, it's always above 100, sometimes even hitting 95 to 105. I'm worried about what could be causing this consistently high pulse rate. Can you help me understand the possible reasons behind it?
