“…If right side dysfunction is suspected, a right-sided ECG is the most sensitive and specific, as ST elevation in V4R >1.0 mm has 100% sensitivity, 87% specificity, and 92% predictive accuracy. Conduction abnormalities such as right bundle branch block, bradycardia, or complete heart block can also manifest themselves in the ECG but may also be non-specific [8][9][10] .…”

Objective: To determine the frequency of right ventricular infarction among patients with acute inferior wall myocardial infarction. Study Design: Descriptive cross sectional study. Place and Duration of Study: Ayub Teaching Hospital, Abbottabad from, Jan 2017 to Sep 2017. Methodology: A total of 163 patients aged 18-75 years and admitted to coronary care unit (CCU) with first attack of acute inferior wall myocardial infarction, were recruited through non probability purposive sampling. Electrocardiogram and Echo were performed of all patients and their findings were noted for the frequency of right ventricular infarction in acute inferior wall myocardial infarction. Results: There were 117 (72%) males and 46 (28%) females. Patients were stratified according to their age in four groups i.e. 13 (8%) patients were less than 40 years of age, 26 (16%) patients were aged between 41 and 50 years, 46 (28%) patients were aged between 51 and 60 years of age and 78 (48%) patients were above 60 years of age. Mean ± SD was 60 ± 1.28. Out of 163 patients, 44 (27%) had right ventricular infarction while 119 (73%) did not have right ventricular infarction. Conclusion: The frequency of right ventricular infraction among patients presenting with acute inferior wall myocardial infarction was 27%.

[17][18][19] In our study, we sampled 104 patients presented with acute onset chest pain diagnosed with inferior wall ST elevation myocardial infarction presenting within 12 hours of onset angina. All patients were subjected to right sided ECG evaluation along with standard 12 lead rhythm strip.…”

Objectives: Right ventricular infarction (RVI) poses as an added risk factor in patients presenting with acute ST elevation inferior wall myocardial infarction (IWMI) with considerable high mortality. An early interventional therapeutic strategy after a prompt and accurate non-invasive investigative correlate is needed. Material and methods: We sampled 104 patients diagnosed with inferior wall infarction presenting with angina within 12 hours of angina. Investigations included routine blood investigation, 12 lead and right precordial lead electrocardiography, right ventricular (RV) systolic echocardiographic indices, and coronary angiography. Results: Majority of the patients had angiographic evidence of a dominant distal right coronary artery (RCA) culprit lesion. Those patients having ST elevation in RV4 lead had significantly higher incidences of RVI and high-grade atrio-ventricular (AV) blocks. Elderly diabetic patients with azotemia and deranged liver function predicted RVI among the study population. RV systolic indices like TAPSE was most accurate and S' was found to be most specific in detecting RVI. Chi square test and multivariate regression analysis of echocardiographic parameters like RVDD, RVMPI, and S' proved excellent surrogate non-invasive surrogate markers for specific angiographic culprit lesions. Conclusion: RV systolic echocardiographic indices shows a diagnostic accuracy of variable degrees in detecting right ventricular involvement in IWMI patients and also act as a surrogate marker in predicting the culprit lesion.

“…Negative T wave locations in an 18-lead ECG provide the critical clue to differentiate between the two diseases 3. Negative T waves in precordial (V1, V2, V3, V4), inferior (especially in II) and posterolateral (V6, syn-V7, syn-V8 and syn-V9) leads reflect pathological conditions of the anterior, inferior and posterolateral myocardium the possibility of a Takotsubo cardiomyopathy should be strongly considered because simultaneous changes in these leads in an AMI is extremely rare.…”

Clinical IntroductionA 69-year-old woman with hypertension and dyslipidemia developed sudden onset of substernal chest pain at night and was admitted to our hospital the following day. A 12-lead and 18-lead ECG (Nihon Kohden, Japan) was done (figure 1A,B).Figure 1(A) Twelve-lead ECG. (B) Eighteen-lead ECG.QuestionWhich is the most likely diagnosis?Reperfused anterior acute myocardial infarctionTakotsubo (stressed) cardiomyopathyPericarditisApical hypertrophic cardiomyopathyFor answer see page 2.
