ST segment elevation of >3-5 mm in I and aVL in association with ST elevation in precordial leads was another criteria used among our patients and was seen among 42% cases in our study.
The Brugada pattern includes a pattern resembling RBBB with elevation of the ST segment in the precordial leads (V1V2).
A standard twelve lead ECG with right precordial leads V1R to V6R was performed in all patients.
There are three different ECG patterns and in all three types, the ECG shows [greater than or equal to] 2mm J point (junction between the termination of QRS complex and beginning of ST segment) elevation and a characteristically shaped ST segment in the right precordial leads (6).
Long-term follow-up of individuals with the electrocardiographic pattern of right bundle-branch block and ST-segment elevation in precordial leads VI to V3.
The classic (type 1) Brugada syndrome presents with the coved-type ST elevation in more than 1 right precordial lead, V1 through V3, with or without a sodium channel blocker, with one of the following criteria: syncope, documented ventricular fibrillation, electrophysiological inducibility of ventricular tachycardia, positive family history of cardiac death younger than age 45, nocturnal agonal respiration, self-terminating polymorphic ventricular tachycardia, and type 1 ST elevation in family members.
Case-reports have demonstrated a strong association between biphasic inversions of T-waves in precordial leads on electrocardiogram (ECG) with severe stenosis in the proximal part of the left anterior descending (LAD) coronary artery in patients with ischaemic heart diseases (IHD).
Patients with typical chest pain ongoing >30 min, 2 mm ST-elevation in at least two adjacent precordial leads, >1 mm in standard leads were classified as "ST-elevation myocardial infarction".
Repolarisation abnormalities Major Minor * Inverted T waves in right * Inverted T waves in leads V1 precordial leads (V1, V2, and V3) or and V2 in individuals>14 years beyond in individuals >14 years of of age (in the absence of age (in the absence of complete RBBB complete RBBB) or in V4, V5, or QRS [greater than or equal to]120 V6 MS) * Inverted T waves in leads V1, V2, V3 and V4 in individuals >14 years of age in the presence of complete RBBB IV.
A 12-lead electrocardiogram showed ST-segment elevation in the precordial leads and reciprocal inferior ST-segment depression compatible with an anterolateral acute myocardial infarction.
ECG: The ECG in ARVD/C patients usually show a regular sinus rhythm, with a QRS duration of greater than 110 milliseconds in lead V1 and an inversion of T waves in precordial leads V1-V3.
For example, a common finding may be inverted T waves shown on the precordial leads of the electrocardiogram normally present in African American males (Campinha-Bacote, 2003).
