There are many disorders of the heart rhythm or blood pressure that do not show up on your visit with a physician. The difficult part of diagnosing some conditions is that you may not be having a symptom when you see the doctor. At Hartford Cardiology Group, we use the latest technology to help diagnose these problems. Some patients experience palpitations or episodes of light-headedness that are very frightening. We have our patients wear small portable devices that can watch every heart beat they have for 24 hours up to a month, if necessary, until we find the problem. Similarly, many people have high blood pressure, hypertension, but are not adequately controlled. The answer could be in changing the type or timing of medications. Dr. Knox is a Specialist in Clinical Hypertension. We use 24-hour blood pressure monitors that patients can wear home to get a true representation of their real blood pressure burden. Medical and lifestyle modifications can be made with this data.
