Posterior myocardial infarction (MI) accompanies 15-20% of STEMIs, usually occurring in the context of inferior or lateral infarction. Isolated posterior MI is less common (5-10% of infarcts), and the lack of ST elevation means that the diagnosis is often missed. Posterior extension of an in...
We have reported in the past on an ECG appearance suggestive of an acute PMI in the presence of complete RBBB, which consists of the acute development of tall R waves involving the early part of the QRS complex, and tall T waves, both noted in the right precordial leads. The 2 ...
A 60 year old woman with 3 hours of chest pain. Acute posterior myocardial infarction (hyperacute) the mirror image of acute injury in leads V1 - 3 (fully evolved) tall R wave, tall upright T wave in leads V1 -3 usually associated with inferior and/or lateral wall MI...
Reperfusion after coronary occlusion (myocardial infarction, MI), as in Wellens' syndrome, is often represented on ECG as T-wave inversion in the leads overlying the affected myocardial wall(s). As an extension of this logic, reperfusion of the posterior wall should manifest on right precordial...

The Philips Diagnostic ECG algorithm was used to classify multiple combinations of the extended leads. Results The below table lists the algorithm's right and posterior MI detection performance when including different combinations of right and posterior leads. Detection of RV involvement based on ...
Because the posterior wall is faced by none of the 12 standard electrocardiographic (ECG) leads, the ECG diagnosis of posterior infarction is problematic and has often remained undiagnosed, especially in the acute phase. Methods. Eighty-seven patients with a first inferior infarction who were ...
ST elevation in lead III greater than II of at least 1mm on the Standard 12-lead electrocardiogram (ECG) has been shown to have high sensitivity and positive predictive value of RV infarction. We conducted aprospective study on allpatients whopresented with acute inferior MI and were admitted ...
Patients Fifty-two patients admitted to the CCU with acute evolving inferior MI. Outcome measures Correlation and comparison of the predictions of right ventricular (RV) and posterior wall (PW) lead ST elevation with prospectively chosen markers on the 12-lead electrocardiogram鈥擲T elevation in ...
Background: For patients with persistent atrial fibrillation (AF), whether linear ablation should be performed remains controversial, and the efficacy and safety for ablation index (AI)-guided high-energy linear ablation of mitral isthmus (MI) and left a
