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.[1] 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.[citation needed]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
