原文：I've been using this for over a year now. My readings are always higher at the doctor's office, so I wondered about the accuracy of this machine. To me, my readings always made sense. I used to have very high blood pressure, and the high readings coincided with the headaches. These days, I'm in much
better shape, but it was dropping low - especially after a cardio workout, and if I took a medication too soon afterward, the very low readings explained the strange feeling and blurred vision (when it got down to 110 or lower). I've kept good records of my numbers, and brought in spreadsheets for the doctor, who said my numbers looked awesome...but then on every visit, BP would be higher.Not being one to just blindly take more meds with side effects (and I recently quit one), I had to settle a dispute. I took my monitor in, and we compared results. The first set of readings matched perfectly - systolic, diastolic, and even the pulse. We waited a few minutes, and tried again. The second readings were still extremely close - off by only 2-3 points (and closer to normal because they allowed me to sit for a few minutes). It proved that my BP is higher during an office visit (not concerned about that), but more importantly, it proved that my everyday normal readings are valid, so I can manage my health with confidence.I saw another review by someone who tried this same experiment and got inaccurate readings. I can only report on my own experience, and this model seems very accurate.The nurse was quite impressed with it, and made a note of which model I have. The price has really dropped on this, too. I paid around $100 for mine just over a year ago, and then bought a second one last month as a gift for only $64.

译文：
我已经用了一年多了，欧姆龙测出来的读数总是比我在医生办公室测的读数高，所以我想知道这个血压计的准确性。对我来说，我认为这个读数是准确的。我过去的血压很高，读数高的时候会头疼。这些天，我的身体状况好多了，但是血压降得很低特别是在进行有氧运动之后，如果我过早服药，读数就会很低，这也就可以解释我奇怪的感觉和模糊视力的现象了（它下降到110或更低）。我一直记录好我的读数，还给医生发了电子表格，他说我的读数看起来很棒。但每次检查时，血压都会更高。
我不是那种会盲目服用副作用很多的药物的人（我最近放弃了一种药），我必须解决一个问题，我用的这个血压计，比较了结果。第一组读数完全吻合收缩压，舒张压，甚至脉搏。我们等了几分钟，又试了一次。第二组读数仍然非常接近，只差2-3点（更接近正常，因为他们让我坐了几分钟）。事实证明，我的血压在办公室检查的时候会更高（我不关心这个），更重要的是，这证明我每天的正常读数是有效的，所以我可以自信地管理我的健康。
我看到了另一个人的评论，他做了同样的实验，得到了不准确的读数。我只能根据自己的经验说，这个型号看起来非常准确。护士对此印象深刻，还记下了我的型号。价格也确实下降了。我一年前花了100美元买的，然后上个月又买了一个，只花了64美元。
