In electrocardiography, a
strain pattern is a well-recognized marker for the presence of anatomic left ventricular hypertrophy (LVH) in the form of
ST depression and
T wave inversion on a resting ECG.
[Okin, PM Devereux, RB, Nieminen, MS et al (2001), “Relationship of the electrocardiographic strain pattern to left ventricular structure and function in hypertensive patients: the LIFE study”; Journal of the American College of Cardiology;38(2):514-520. doi:10.1016/S0735-1097(01)01378-X] It is an abnormality of
repolarization and it has been associated with an adverse prognosis in a variety heart disease patients. It has been important in refining the role of ECG LVH criteria in cardiac risk stratification. It is thought that a strain pattern could also reflect underlying coronary heart disease. Floyd strain includes T-wave inversion "Floyd.".
