One cause of atrial fibrillation is hypertension. Because I have paroxysmal afib, I have been advised by my electrophysiolgist to take my blood pressure and pulse readings daily. By submitting the readings to the doctor, he can adjust my blood pressure medications to keep my blood pressure and pulse rate in check and hopefully prevent an afib episode from occurring.I used to have an older style Omron blood pressure monitor, but I needed a monitor that would confirm that I was experiencing an irregular heartbeat. **The Omron Automatic Blood Pressure Monitor, Model HEM-711AC **with Intellisense fit the bill perfectly. When the monitor detects that my heartbeat is in afib, an Irregular Heartbeat Symbol will appear on the display. The symbol is a heart with two lines to the right of the heart which gives the appearance of a "shaky heart". This symbol will appear if my heart rhythm is 25% faster or 25% slower than the average rhythm detected while the unit is measuring my blood pressure.The only complaint I have with the **Omron HEM-711AC **is when I am experiencing a very fast, erratic heartbeat in afib, the monitor will display an "E" which means it could not detect my pulse wave and a blood pressure reading could not be obtained. Consequently, I have no readings to relay to my doctor when I call him to tell him I am in afib.My regular daily readings are no problem. To ensure a correct blood pressure reading, I avoid eating, drinking, exercising, or bathing for 30 minutes prior to a measurement. I rest for about 10 - 15 minutes before I place on the cuff. I sit on my chair with my feet flat on the floor and I remove any clothing from my right arm. I rest my right arm on my desk with the cuff being placed at heart level. Taking a measurement is very easy - after the cuff is placed on my arm according to the instructions in the manual, I press the Start/Stop button and the cuff inflates automatically. I remain still until the measurement is completed. At this time, the cuff deflates and my blood pressure and pulse rate are displayed. I take two measurements 3 minutes apart. The second measurement is the one I record to submit to my doctor. If my blood pressure is above 135 for the systolic reading or above 85 for the diastolic reading, a heartbeat symbol on the monitor which flashes during your measurement will continue to flash when the measurement is completed.The **Omron HEM711AC **has a date and time feature that can be set and is very helpful. However, the best feature I like about this monitor is the Memory Function. The monitor stores up to 60 sets of blood pressure and pulse rate readings. It automatically calculates the average reading based on the three most recent values taken within ten minutes of the last reading. I can delete these readings daily, weekly, or whenever I wish.You will not find another monitor for the price that is so user friendly and accurate. Thank you for reading my review.
