Low Diastolic?

Question

I am 2 years post gastric bypass. I weighed 365lbs at the highest. I am now down to 220lbs. I had my BP taken by an EMT the other day because I was feeling dizzy. The systolic was fine at 126, but the diastolic was 0. It had an audible beat all the way down. I have no history of BP problems. The only symptom would be dizzyness and near syncopal episodes upon suddenly standing up. Is the low diastolic a problem and what would the causes be?

It was audible with just the stethescope. However you want to word that, the cuff went all the way to zero and you could still here the beating.

Answer 1

. Sounds like it could be an error, you should get it checked again. if its still low, see your doctor

Answer 2

You can't have a diastolic of 0. If you do your heart never relaxes and you may have serious heart problems. I would have it taken again. Your systolic looks good though. Remember systolic is when your heart contracts and disstolic is when it relaxes. No diastolic and your heart is going to wear out and quit fast and it has to grow silent at some point. Have it retaken. 0 is not a reading. Whoever took it needs to practice a little more; sure you may hear a beat for a long time but all the way to 0? No way. If your diastolic were that low you could hear your pulse by putting the stethocope up to your arm and not using a blood pressure cuff at all. Retake and have someone else take it. I have no doubt it may be low. However syncope can result from dehydration which could be explained by being post gastric bypass. Also syncope can be caused by medications and or your electrolytes being to low or to high (imbalanced electrolytes can be life threatening in severe cases, But don't drop everything and go running ot the ER) and several other causes. So now here's what you need to do:
1. Have someone else take your blood pressure again
2. Drink plenty of fluid (or as much as allowed)
3. Check any medications you may be taking. Read the side effects.

Answer 3

I'm a paramedic, and I've never heard of some one having a diastolic pressure of 0 (and still be alive). The person taking the reading probably needs to slow down when he or she lets the air out of the cuff.
I'm darn near positive that the reading was just done improperly.
You might want to check with your primary care provider just to be sure, though.
Hope this helps!
