To study the value of the electrocardiogram in diagnosing right ventricular involvement in acute inferior wall myocardial infarction, the electrocardiographic findings were analysed in 67 patients who had had scintigraphy to pin-point the infarct. All 67 patients were consecutively admitted because of an acute inferior wall infarction. A 12 lead electrocardiogram with four additional right prec...

BACKGROUND Changes in the amplitude of the R wave (RWA) on the electrocardiogram (ECG) have been described during acute myocardial ischemia and infarction. However, this has not been well studied in a controlled setting. We hypothesized that significant increase in RWA occurs during early transmural myocardial ischemia. METHODS We prospectively evaluated changes in RWA in 50 patients during b...

Pulmonary embolism is considered as a great masquerader due to its frequent nonspecific signs and symptoms. Typically pulmonary embolism is under-diagnosed or over-diagnosed. In this study a patient with pulmonary embolism is reported in which the patient exhibited two unusual manifestations namely; right upper quadrant abdominal pain and ST-T elevation in anterior precordial leads. Due to the ...

"Juvenile pattern" of T wave inversion in the precordial leads of electrocardiogram was studied in 100 normal healthy Indians of 0 to 70 years of age in both sexes. Incidence of such pattern was observed in 25 subjects upto 19 years of age. Persons of weight/height ratio less than 30% had higher incidence of juvenile T waves. Maximum incidence (48%) of juvenile T waves was observed in the annua...

BACKGROUND AND OBJECTIVES We checked traditional and high-level precordial electrocardiogram (ECG) leads in patients who had undergone right ventricular outlet obstruction (RVOT) reconstruction surgery and evaluated the effect of ECG lead position on their QRS duration. SUBJECTS AND METHODS We enrolled 34 patients who had undergone surgery for congenital heart disease with RVOT obstruction an...

BACKGROUND As the myocardium contracts isometrically, it generates vibrations that can be measured with an accelerometer. The vibration peak, peak endocardial acceleration (PEA), is an index of contractility. OBJECTIVE To evaluate the feasibility of PEA measured by the cutaneous precordial application of the accelerometer sensor; and to assess the usefulness of PEA monitoring during pharmacol...

FIGURE 4. Twelve lead electrocardiogram taken on the third hospital day. Note mild ST elevation in La, LJ and aVF; prominent and broad R waves in V2Vq; small but wide R wave in VI; marked ST depression in VI-V~. These findings suggest the presence of acute "true" posterior wall myocardial infarction with diaphragmatic extension. The possibility of severe anterior wall ischemia seems unlikely be...

Pectus excavatum (PE), the most common skeletal anomaly of chest wall, sometimes requires a surgical correction but recurrent PE is not uncommon. PE usually has a benign course; however, this chest deformity may be associated with symptomatic tachyarrhythmias due to mechanical compression. We report a case of a patient with recurrent PE after surgical correction presenting with palpitation and ...

Brugada syndrome is characterized by the presence of right bundle branch block on electrocardiography and by ST-segment elevation in the right precordial leads (V1-V3), by the absence of structural cardiac abnormalities, and by episodes of syncope or sudden death. On occasion, diagnosis is made difficult by temporary normalization of the ECG. The condition can be unmasked by potent sodium chann...

Sixty-nine hospitalized who rest and lasting at least 15 minutes, and whose electrocardiographic changes were limited to deeply inverted T waves predominantly in the precordial leads, were selected from a large series of patients. The hospital course and electrocardiographic changes of these patients were studied. After an average follow-up period of 4 years, approximately half the patients wer...
