BACKGROUND Electrocardiographic (ECG) identification of prior myocardial infarction (MI) during right ventricular (RV) pacing is of clinical importance. Proposed ECG criteria have been evaluated only during apical pacing. We evaluated the effect of pacing site on the predictive performance of ECG signs of prior MI. METHODS The present study is a secondary analysis of a prospective, multicente...

PURPOSE: Right ventricular (RV) involvement occurs in about one-half of patients (pts) with inferior MI and is associated with considerable immediate morbidity and mortality. Accurate identification and precise delineation of RV involvement is essential for appropriate patient management. Diagnosis of this condition is challenging and is typically based on clinical suspicion, early ECG recordin...

The relationship between the resting electrocardiogram and left ventricular contractile pattern, as documented by angiography, was evaluated in 123 patients with coronary artery disease who underwent left ventriculography. Dyssynergy was present in 73/77 (95%) patients with pathologic Q waves on ECG recordings in contrast to 11/46 (24%; P<0.01) without Q waves. The location of Q waves correlate...

ABSTRACT Introduction: Stroke is more common in patients with cerebral microembolisms. Frequency of cerebral microembolisms (high intensity transient signals, HITS) in acute myocardial infarction has been reported about 17%. The factors that influence on microembolism after myocardial infarction (MI) are not definitive. Type of MI, Ejection fraction, Hx of Streptokinase is the factors that were...

OBJECTIVES We assessed the role of late enhancement cardiovascular magnetic resonance imaging (LE-CMR) for the diagnosis of right ventricular infarction (RVI). BACKGROUND Right ventricular infarction occurs in about one-half of patients with inferior myocardial infarction (MI). It is associated with an unfavorable prognosis, but established methods often lack the diagnostic accuracy to detect...

Left ventricular (LV) pseudoaneurysm is a rare but potentially lethal complication of acute myocardial infarction (MI). We report a very rare case of a 60 year-old woman with a ruptured myocardial wall, and a non-ruptured LV pseudoaneurysm. The patient presented with acutely worsening shortness of breath and exertional dyspnea of one month's duration, and palpitation. She had an inferior wall M...

Esansiyel trombositoz (ET) (diğer isimleri, esansiyel trombositemi, idiopatik trombositoz, primer trombozis), sebebi bilinmeyen anormal megakaryosit proliferasyonu ve trombosit sayısında persistan artışla karakterize kronik myeloproliferatif bir hastalıktır. ET de koroner arter oklüzyonu ve miyokard infaktüsü (Mİ) nadir vakalar olarak bildirilmiştir. Bizim vakamız, ET nin ilk klinik bulgusu ola...

OBJECTIVES The purpose of this study was to determine the pathologic basis of Q-wave (QW) and non-Q-wave (NQW) myocardial infarction (MI). BACKGROUND The QW/NQW distinction remains in wide clinical use but the meaning of the difference remains controversial. We hypothesized that measurement of total MI size and transmural extent by late gadolinium enhancement cardiovascular magnetic resonance...
