Abstract

Background: the decrease in cardiac electrical systole (short intervals of PR and QTc in the same electrocardiogram, also known as "Breijo electrocardiographic pattern") is increasingly studied.
Objective: to show the electrocardiographic characteristics of the Breijo electrocardiographic pattern and clinical manifestations.
Development: the vast majority of the time can be overlooked in an electrocardiogram tracing. More than 127 cases have been studied and contrasted. Its diagnosis is essential to avoid the most painful consequence: avoidable death. Although for many authors, cardiac electrical systole comprises only from the beginning of the Q wave to the end of the T wave, that is, the depolarization and repolarization of the ventricles, the atria are also part of it. Therefore, the P wave, as well as the PR segment, must be part of the electrical cardiac systole. When there is a shortening of the PR interval together with a shortening of the QT interval, we should talk about a decrease in the cardiac electrical systole. This peculiar electrocardiographic pattern is called the Breijo pattern: a PR interval of less than 0.120 seconds together with a QTc interval of less than 0.360 seconds.
Conclusions: common characteristics are common in patients with Breijo's pattern: 1.- Nonspecific symptoms that are considered mild, such as: Palpitations, usually nocturnal, that awaken the patient from natural sleep. Deep night sweats and misunderstood feelings of dizziness. 2.- Sensation of nonspecific chest pain, not irradiated and whose electrocardiographic study is considered, in the great majority of cases, as nonspecific and atypical, since no coronary alterations are observed. 3.- Personal history, in childhood, of seizures treated with antiepileptic drugs without the presence of an epileptic focus on the electroencephalogram. 4.- Low levels of litemia. 5.- Preference for young age (up to 40) and male sex.
