The Brugada criteria/algorithm is as follows: 1. Is there concordance present in the precordial leads (leads V1-V6)? Also explained as the absence of an RS complex, concordance is diagnostic of ...

A systematic search was made for the effective axes from an orthogonal lead system that best duplicated the diagnostically significant features of precordial leads. Only one of 240 precordial leads ...

The ECG showed ST-segment depression at the J-point of at least 1 mm in precordial leads with upsloping ST-segments continuing into tall, symmetrical T-waves. Patients with this distinct ECG pattern ...

In a further consecutive study of 54 patients with anterior myocardial infarction, the precordial R waves and Q waves were studied over the four to six months following infarction using a standardised ...

Poor R wave progression refers to the absence of the normal increase in size of the R wave in the precordial leads when advancing from lead V1 to V6. In lead V1, the R wave should be small.
