  2. T wave - Wikipedia

    en.wikipedia.org/wiki/T_wave

    Inverted T wave is considered abnormal if inversion is deeper than 1.0 mm. Inverted T waves found in leads other than the V1 to V4 leads is associated with increased cardiac deaths. Inverted T waves associated with cardiac signs and symptoms (chest pain and cardiac murmur) are highly suggestive of myocardial ischaemia. [4]

  3. ST depression - Wikipedia

    en.wikipedia.org/wiki/ST_depression

    Horizontal ST depression in V4, V5, V6 leads during a cardiac stress ECG. Other, non-ischemic, causes include: Side effect of digoxin [4] [3] Hypokalemia [4] [3] Right or left ventricular hypertrophy [3] Intraventricular conduction abnormalities (e.g., right or left bundle branch block, WPW, etc.) [3] Hypothermia [4] Tachycardia [4] Reciprocal ...

    en.wikipedia.org/wiki/ST_elevation

    12-lead electrocardiogram showing ST-segment elevation (orange) in I, aVL and V1–V5 with reciprocal changes (blue) in the inferior leads, indicative of an anterior wall myocardial infarction. When there is a blockage of the coronary artery , there will be lack of oxygen supply to all three layers of cardiac muscle (transmural ischemia).

    en.wikipedia.org/wiki/Takayasu's_arteritis

    Takayasu's arteritis (TA), also known as aortic arch syndrome, nonspecific aortoarteritis, and pulseless disease, [2] is a form of large vessel granulomatous vasculitis [3] with massive intimal fibrosis and vascular narrowing, most commonly affecting young or middle-aged women of Asian descent, though anyone can be affected.

  6. Arrhythmogenic cardiomyopathy - Wikipedia

    en.wikipedia.org/wiki/Arrhythmogenic_cardiomyopathy

    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 ...

    Congenital heart problems e.g. pulmonary artery stenosis (common), Tetralogy of Fallot, overriding aorta, ventricular septal defect; and right ventricular hypertrophy. Liver (jaundice, pruritus, hepatosplenomegaly, acholia, xanthoma) Andersen–Tawil syndrome: This condition affects the QT interval (in blue) Antley–Bixler syndrome: Barth syndrome
