In pulmonary embolism, T wave can be symmetrically inverted at V2 to V4 leads but sinus tachycardia is usually the more common finding. T wave inversion is only present in 19% of mild pulmonary embolism, but the T inversion can be present in 85% of the cases in severe pulmonary embolism. Besides, T inversion can also exists in leads III and aVF ...
Takotsubo syndrome represents about 2% of all patients (and 5–6% of all female patients) who are initially diagnosed with acute coronary syndrome (ACS). [6] [69] It accounts for 0.02% of all hospitalizations in the US. [6] About 90% of TTS patients are women, [6] [69] whose mean age is about 68 years, and 80% of whom are older than 50 years. [6]
Hyperacute T waves need to be distinguished from the peaked T waves associated with hyperkalemia. [16] In the first few hours the ST segments usually begin to rise. [17] Pathological Q waves may appear within hours or may take greater than 24 hr. [17] The T wave will generally become inverted in the first 24 hours, as the ST elevation begins to ...
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.
Originally thought of as two separate types, A and B, it is now considered an evolving wave form, initially of biphasic T wave inversions and later becoming symmetrical, often deep (>2 mm), T wave inversions in the anterior precordial leads. [1]

At this point there may be signs of ventricular strain pattern (ST segment depression and T wave inversion) on the EKG, suggesting subendocardial ischemia. The subendocardium is the region that is most susceptible to ischemia because it is the most distant from the epicardial coronary arteries.
