**6. Some significant images typical of the Breijo pattern**

A typical image of a Breijo pattern in precordial left leads (**Table 2**).

Measured PR interval: 0.988 s.

Calculated QTc interval:

The last electrocardiogram performed with a **Breijo pattern**, in a male person who unfortunately died due to not being able to be recovered from a sudden death.

The electrocardiographic tracing was considered as within acceptable limits and his doctors decided to send him home (**Figure 9**).

PR interval value: 0.89 s (Very short).

Measured QTc value: Between 0.356 and 0.334 s very short).

In a nutshell, we can say the following about Breijo pattern as conclusions:

**1.** Although relatively little known so far, it is increasingly being discovered in ECG tracings that at first glance may appear normal.

**2.** The accurate reading of the ECG tracing must be of mandatory compliance. Despite the fact that symptoms referred by patients may be slight.
