Division of Cardiology, Helsinki University Central Hospital, PL 340, 00029 HUS, Finland
Ann Noninvasive Electrocardiol 7:389-98. 2002....- Increased intra-QRS fragmentation in magnetocardiography as a predictor of arrhythmic events and mortality in patients with cardiac dysfunction after myocardial infarctionPetri Korhonen
Division of Cardiology, Helsinki University Central Hospital, PL 340, 00029 HUS, Finland
J Cardiovasc Electrophysiol 17:396-401. 2006..The aim of this study was to investigate whether increased FRA in MCG predicts arrhythmic events and mortality after acute myocardial infarction (MI) with cardiac dysfunction... - Complex T-wave morphology in body surface potential mapping in prediction of arrhythmic events in patients with acute myocardial infarction and cardiac dysfunctionPetri Korhonen
Division of Cardiology, Helsinki University Hospital, PL 340, 00029 HUS Helsinki, Finland
Europace 11:514-20. 2009..This prospective study investigated repolarization disparity with parameters based on T-wave morphology in body surface potential mapping (BSPM) in the assessment of arrhythmia risk in patients with a recent MI and cardiac dysfunction... - Single-lead electrocardiographic variables in the detection of prior myocardial infarction with respect to Q-wave status and infarct agePaula Vesterinen
Division of Cardiology, Helsinki University Central Hospital, Helsinki, Finland
Cardiology 109:222-9. 2008..Conventionally, the detection of prior myocardial infarction (MI) is based on QRS abnormalities, which may ignore non-Q-wave MI (NQMI). We aimed at finding automatically applicable quantitative ECG variables for diagnosing prior MI... - Dynamic QT/RR relationship in post-myocardial infarction patients with and without cardiac arrestJere Järvenpää
Department of Cardiology, Helsinki University Central Hospital, Helsinki, Finland
Scand Cardiovasc J 44:352-8. 2010..We tested the hypothesis that dynamic QT/RR relationship might differ between post-MI patients with and without a history of VF. We also evaluated the influence of negative T-waves on the assessment of QT/RR relationship... - Fragmented QRS in prediction of cardiac deaths and heart failure hospitalizations after myocardial infarctionPetri Korhonen
Helsinki University Hospital, Finland
Ann Noninvasive Electrocardiol 15:130-7. 2010..We investigated user-independent computerized intra-QRS fragmentation analysis in prediction of cardiac deaths and heart failure (HF) hospitalizations after MI... - Localization of prior myocardial infarction by repolarization variablesPaula Vesterinen

Division of Cardiology, Helsinki University Central Hospital, HUS, Finland
Pacing Clin Electrophysiol 25:1339-45. 2002..MCG parameters indicating postinfarction arrhythmia propensity are related to delayed ventricular conduction. Abolition of the arrhythmia substrate reverses the abnormality of these parameters... - Changing capacity of electrocardiographic ventricular repolarization in post-myocardial infarction patients with and without nonfatal cardiac arrestJere Järvenpää
Department of Cardiology, Helsinki University Central Hospital, Helsinki, Finland
Am J Cardiol 99:295-9. 2007..01 to <0.001, respectively). In conclusion, long maximal QT interval may not be the key factor exposing patients after MI to VF. Impaired capacity to change QT and TPE intervals seems to be associated with risk of VF after MI... - Features of ST segment and T-wave in exercise-induced myocardial ischemia evaluated with multichannel magnetocardiographyHelena Hänninen
Division of Cardiology, Helsinki University Central Hospital, Finland
Ann Med 34:120-9. 2002..Magnetocardiography (MCG) is a novel, non-contact mapping technique to record cardiac magnetic field. We evaluated MCG criteria for myocardial ischemia in stress testing... - Noninvasive determination of the activation sequence of the heart: application to patients with previous myocardial infarctionsThom Oostendorp
Laboratory of Medical Physics, University of Nijmegen, The Netherlands
J Electrocardiol 35:75-80. 2002..The results of this study showed that one cannot expect good results from the UDL-based inverse in the presence of an old myocardial infarction unless that infarction is accounted for in the inverse procedure...
