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.

View allI'm really puzzled about my friend's sudden passing. He was perfectly fine until about 10:30 in the morning, but out of nowhere, he had a severe cardiac arrest and died by 10:50. In the 48 days leading up to his death, he rarely ate food from home. I can't help but wonder if there might be anything like a slow poison that could have affected him. Could you shed some light on what might have happened?
While I understand your concern about potential poisoning given the changes in his eating habits, sudden cardiac arrest can happen without warning even in people who appear healthy. The period of irregular eating could be related to various factors like stress, depression, or underlying health issues. If you have serious concerns about the circumstances, I would encourage you to share them with the relevant authorities and discuss with his family about requesting an autopsy if one hasn't been performed. Most importantly, please make sure you're getting support during this difficult time - losing someone suddenly is incredibly challenging, and it's natural to have questions and seek answers about what happened.

I'm dealing with high blood pressure since 2020 and I often have headaches and chest pain. My average blood pressure is around 150100. My doctor has prescribed me olmesartan 20mg. Should I be concerned about these symptoms, and is the medication dosage suitable?
Since you are already taking olmesartan 20mg for your high blood pressure, it is important to continue with the medication as prescribed by your doctor. In addition to olmesartan, you can also consider adding a calcium channel blocker such as Amlodipine 5mg to further control your blood pressure. It is important to monitor your blood pressure regularly and follow up with your doctor for any necessary adjustments to your treatment plan.

I'm having this continuous chest pain since morning, and I think it might be a gas lock. I had dosa this morning, but I've been struggling with this issue for about 10 days now. I've been taking homeopathy, but it doesn't seem to be helping much. Could it still just be gas, or do you think it's something else? Should I consider a different treatment?
