Breijo’s Pattern: A Shortened of Cardiac Electrical Activity

The decrease of the cardiac electrical systole – short PR and QTc intervals in the same electrocardiogram, also known as “Electrocardiographic Breijo Pattern” - is increasingly studied by several authors. The vast majority of the time it can be overlooked in an electrocardiogram tracing. People who had this kind of electrocardiographic pattern had also suffered from a wide variety of symptoms. Nocturnal tachycardias, dizziness, seizures, and unexplained syncopal accesses were the main symptoms common to all patients. More than 127 cases have been studied and cross-checked by our research team so far. Its diagnosis is indispensable in eluding of the most heartbreaking consequence: avoidable death. Despite the fact that for many authors, the cardiac electrical systole comprises only from the beginning of the Q wave to the end of the T wave – that is, depolarization and repolarization of the ventricles, the atria are also part of it. Consequently, the P wave, as well as the PR segment, must be a part of the electrical cardiac systole. When there is a shortening of the PR interval along with a shortening of the QT interval, we should talk about: Decrease of cardiac electrical systole.
