electrocardiography Electrocardiography is the process of producing an electrocardiogram (ECG or EKG), a recording of the heart's electrical activity. It is an electrogram of the heart which is a graph of voltage versus time of the electrical activity of the hear ...

, 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
