Differential Diagnosis of Causes of Non Specific ST segment and T Wave changes ^[1]

Adrenal insufficiency
Anxiety
Central nervous system diseases
Congestive heart failure
Gallbladder disease
Heart failure
Hyperkalemia
Hyperventilation (in 70% of patients after 30 to 60 seconds)
Hypokalemia
Hypopituitarism
Hypothyroidism
Ischemic heart disease
Left ventricular hypertrophy (LVH)
Mitral valve prolapse (MVP)
Orthostatic changes (3 to 23%), most prominent in the inferior leads
Pacemaker
Pancreatitis
Pheochromocytoma
Postprandial T-waves changes. One of the most common causes. 50% of patients will have normal EKGs when repeated in the fasting state.
Pulmonary embolism
Pericarditis
Right ventricular hypertrophy (RVH)
Truncal vagotomy
