ECG would be abnormal in 75 to 95% of the patients. Characteristic ECG changes would be large QRS complex associated with giant T wave inversion [4] in lateral leads I, aVL, V5, and V6, together with ST segment depression in left ventricular thickening. For right ventricular thickening, T waves are inverted from V2 to V3 leads.
stage 3 -- diffuse T wave inversions (may not be present in all patients) stage 4 -- EKG becomes normal OR T waves may be indefinitely inverted; The two most common clinical conditions where ECG findings may mimic pericarditis are acute myocardial infarction (AMI) and generalized early repolarization.

The TWA test uses an ECG measurement of the heart's electrical conduction using electrodes attached to one's torso. It takes approximately a half-hour to perform on an outpatient basis. The test looks for the presence of repolarization alternans (T-wave alternans), which is variation in the vector and amplitude of the T wave component of the ...
Progressive symmetrical deep T wave inversion in leads V2 and V3; Slope of inverted T waves generally at 60°-90° Little or no cardiac marker elevation; Discrete or no ST segment elevation; No loss of precordial R waves.
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.
90% of individuals with ARVD have some EKG abnormality. The most common EKG abnormality seen in ACM is T wave inversion in leads V 1 to V 3. However, this is a non-specific finding, and may be considered a normal variant in right bundle branch block (RBBB), women, and children under 12 years old. RBBB itself is seen frequently in individuals ...
ECG findings may include diffuse S-T segment elevation, diffuse T wave inversion, low QRS voltage, and/or electrical alternans. [ 4 ] [ 6 ] Echocardiogram may be used to evaluate for fluid collection in the pericardial sac, and may be important in guiding therapy in patients with signs of cardiac compromise (i.e., cardiac tamponade).
