For several years I occasionally get light headed. At times I have to sit down or I would fall down. last a few minutes. Take no action and it goes away. Today it happened and I immediately checked blood pressure, it was 72/62 pulse 141, 2 minutes later it was 74/61 pulse 87, 7 minutes later it was 144/80 pulse 81. I took no action, no eating, drinking, just sitting in chair checking pressure. Took a few times for machine to get last pressure. Rest of day was fine.
