Methods: A representative sample of Finnish subjects (n = 6,354) aged over 30 years underwent a health examination including a 12-lead ECG in the Health 2000 survey. ECGs with T-wave inversions were divided into three anatomical lead groups (anterior, lateral, and inferior) and were compared...
Wellens' syndrome or LAD coronary T-wave syndrome is an acute coronary syndrome characterized by ECG changes of symmetric, deeply inverted T waves or biphasic T waves in the anterior leads with preserved R wave progression and without pathologic Q waves and ST-segment elevation. Interestingly, ...

Ventricular repolarization components on the surface electrocardiogram (ECG) include J (Osborn) waves, ST-segments, and T- and U-waves, which dynamically change in morphology under various pathophysiologic conditions and play an important role in the development of ventricular arrhythmias. Our primary ...
Acute myocarditis may mimic myocardial infarction, since affected patients complain of "typical" chest pain, the ECG changes are identical to those observed in acute coronary syndromes, and serum markers are increased. We describe a case series of presumptive myocarditis with ST segment elevation on ...
The clinical significance of the negative U wave was examined in 488 consecutive patients. A negative U wave was highly specific for the presence of heart disease and was associated with other ECG abnormalities in 94.9% of patients. The three most common conditions associated with negative U wave...
Three of the latter eventually died, in contrast with the single death in the 22 patients who did not develop cerebral arterial spasm and had a low incidence of P wave peaking, short P-R intervals, a long Q-Tc, and tall U waves. Various combinations of these four ECG changes, in ...
Objectives: To investigate clinical significance of liver and spleen stiffness in patients with chronic parenchymal liver disease. Materials and Methods: Fifty patients with chronic parenchymal liver disease who underwent 2D ultrasound (US) shear wave elastography (SWE) in the Ul...
