Heart coronary arteries, a photo by Patrick J. Lynch on Flickr.
It was a fine Sunday morning some months ago, after having late breakfast, I took a tablet of Metoprolol, a medicine used to treat hypertension. That was the second medicine prescribed to me since Amlodipine did not effectively lower my blood pressure. About 45 minutes later while I was already walking towards church to attend the service, I felt like I would pass out. However, I didn't see stars and my vision remained clear. Thankfully I didn't black out although the feeling was like I had lead shoes and I was in need of a cane to steady my weakened knees. I was alone so my instinct was to look around and find something to hold on to. No poles, post, or wall near enough so I had to keep walking and get to church as soon as I can, maybe get help if the condition worsens. It was like going extremely low on battery, like energy oozing from my body. I was glad to be able to sit down after that walk that normally takes me less than 5 minutes only but that instance, it might have taken me twice as long.
