Certain drugs including anti-arrhythmics, psychotropics, and cocaine that may induce ST elevation in right
precordial leads should be avoided in patients with known Brugada syndrome (11).
The Brugada pattern includes a pattern resembling RBBB with elevation of the ST segment in the
precordial leads (V1V2).
The present study was aimed to determine ST-Segment elevation in right
precordial leads in patients with pertinent clinical findings to find out the frequency of RVI at our centre Liaquat Medical College Hospital, Hyderabad14.
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).
TABLE 3 4 diagnoses and what you'll see on EKG Diagnosis EKG finding Prolonged QTc interval >.450 sec (men) or QT interval >.470 sec (women) Brugada syndrome Partial or complete RBBB, and ST segment elevation in right
precordial leads V1-V3 Wolff-Parkinson- Delta wave, widened QRS, short White syndrome PR interval, ST segment and T-wave changes Hypertrophic No definitive finding; may have cardiomyopathy left ventricular hypertrophy or abnormal Q-waves EKG, electrocardiogram; RBBB, right bundle branch block.

precordial leads," Journal of Cardiovascular Electrophysiology, vol.
Electrocardiogram obtained in emergency department during the chest pain revealed ST segment elevations and inverted T waves in
precordial leads. He was taking oral anticoagulation therapy and his INR was 2.8 at hospital admission.
The ECG shows ST segment elevation in the
precordial leads V1 to V3, with morphology of the QRS complex resembling a right bundle branch block.
A resting electrocardiogram (ECG) revealed sinus tachycardia with a rate of 126 beats/min, normal QRS axis, widespread ST-segment depression in the limb and
precordial leads, with ST-segment elevation in the augmented unipolar limb lead (right arm) 0 aVR.
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).

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.
