    PR-segment depression with multilead ST-segment elevation and ST-segment depression in lead aVR are classic ECG manifestation of acute pericarditis. We present a patient, where the etiology of these ECG features was acute ST-elevation myocardial infarction due to left circumflex artery occlusion. To avoid misdiagnosis, unnecessary examinations, and inappropriate therapeutic decisions, the possibility of ST-segment elevation myocardial infarction should be kept in mind even when ECG changes typical for pericarditis are encountered in chest pain patients. Findings of QRS widening and QT interval shortening in leads with ST-segment elevation could help to differentiate acute ST-segment elevation myocardial infarction from acute pericarditis

    Incorrect lead placement may result in unnecessary therapeutic interventions. We present a case report of 53-year-old man with new inferior T-wave inversions in the 12-lead electrocardiogram (ECG) noted during routine followup of hypertension without any cardiovascular symptoms

    Aikuisurheilijan EKG-muutokset

    Urheilijan EKG-muutokset heijastavat sydämen rakenteellista ja sähköistä uudelleen muovautumista. Monet muutokset ovat tavanomaisten tulkintakriteerien mukaan poikkeavia ja viittaavat sydänvikaan. Siksi on tärkeää erottaa urheilijansydämeen liittyvät EKG-muutokset poikkeavuuksista, jotka viittaavat sydänsairauteen, kuten kardiomyopatiaan, sydänlihastulehdukseen tai sydämen sähköisen järjestelmän vikaan. Erotusdiagnostiikan kansainvälisiä kriteerejä muokataan tutkimustulosten perusteella. Niiden mukaan osa EKG-muutoksista, kuten harva sinusrytmin syketiheys ja pidentynyt PQ-aika, ovat selvästi hyväksyttäviä, kun taas toiset, kuten vasen haarakatkos, vaativat jatkoselvittelyjä. Urheilutausta selittää osan muutoksista, esimerkiksi vasemman kammion hypertrofian EKG-muutoksen, joka esiintyy yksin. T-aallon inversiot aiheuttavat eniten tulkintaongelmia. Sivuseinämäkytkentöihin (I, aVL, V5 ja V6) paikallistuvat T-inversiot edellyttävät tarkkoja kuvantamistutkimuksia

    Dilemma in predicting the infarct-related artery in acute inferior myocardial infarction: A case report and review of the literature

    The electrocardiogram (ECG) has being used for decades as a reliable and inexpensive tool to diagnose acute myocardial infarction (AMI). ECG diagnosis of an occluded coronary artery is of the utmost importance. We present the case of a 46 year-old man admitted to our hospital for inferior AMI. The ECG findings suggested right coronary artery occlusion. Coronary angiography showed left circumflex artery occlusion. We also briefly review the literature. (Cardiol J 2011; 18, 2: 204-206

    Solunsalpaajahoidon aiheuttama sepelvaltimotautikohtaus

    Kapesitabiini on mm. paksusuoli- ja rintasyövän hoidossa laajasti käytetty 5-fluorourasiiliksi metaboloituva suun kautta otettava solunsalpaaja. Sen sydämeen kohdistuvien haittavaikutuksien on ajateltu olevan harvinaisia. Kuvaamme neljä potilasta, joille ilmaantui sepelvaltimotautikohtaus kapesitabiinihoidon aikana sepelvaltimospasmin pohjalta. Tämä haittavaikutus kannattaa muistaa kapesitabiinia käyttävän potilaan rintakipuoireiden yhtenä syynä, ja lääkkeen käyttö tulee tätä epäiltäessä lopettaa. English summary: Coronary artery disease attack caused by cytotoxic chemotherapy Capesitabine is a orally administered cytotoxic drug metabolized to 5-fluorouracil and is widely used in large intestine cancer and breast cancer therapy. Its adverse effects against the heart have been considered to be rare. We describe four patients, who were diagnosed with an attack of coronary artery disease during capesitabine therapy on the basis of coronary spasm. This adverse effect should be kept in mind as a cause of chest pain symptoms and the medication discontinued in a suspected case

    Comparison of the prognostic role of Q waves and inverted T waves in the presenting ECG of STEMI patients

    Background Both Q waves and T-wave inversion (TWI) in the presenting ECG are associated with a progressed stage of myocardial infarction, possibly with less potential for myocardial salvage with reperfusion therapy. Combining the diagnostic information from the Q- and T-wave analyses could improve the prognostic work-up in ST-elevation myocardial infarction (STEMI) patients. Methods We sought to determine the prognostic impact of Q waves and TWI in the admission ECG on patient outcome in STEMI. We formed four groups according to the presence of Q waves and/or TWI (Q+TWI+; Q-TWI+; Q+TWI-; Q-TWI-). We studied 627 all-comers with STEMI derived from two patient cohorts. Results The patients with Q+TWI+ had the highest and those with Q-TWI- the lowest 30-day and one-year mortality. One-year mortality was similar between Q-TWI+ and Q+TWI-. The survival analysis showed higher early mortality in Q+TWI- but the higher late mortality in Q-TWI+ compensated for the difference at 1 year. The highest peak troponin level was found in the patients with Q+TWI-. Conclusion Q waves and TWI predict adverse outcome, especially if both ECG features are present. Q waves and TWI predict similar one-year mortality. Extending the ECG analysis in STEMI patients to include both Q waves and TWI improves risk stratification.Peer reviewe
