  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. Wellens' syndrome - Wikipedia

    en.wikipedia.org/wiki/Wellens'_syndrome

    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.

  4. Right heart strain - Wikipedia

    en.wikipedia.org/wiki/Right_heart_strain

    Electrocardiogram of a person with pulmonary embolism, showing sinus tachycardia of approximately 100 beats per minute, large S wave in Lead I, moderate Q wave in Lead III, inverted T wave in Lead III, and inverted T waves in leads V1 and V3.

    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 ...

  6. Electrocardiography - Wikipedia

    en.wikipedia.org/wiki/Electrocardiography

    T wave: The T wave represents the repolarization of the ventricles. It is generally upright in all leads except aVR and lead V1. Inverted T waves can be a sign of myocardial ischemia, left ventricular hypertrophy, high intracranial pressure, or metabolic abnormalities. Peaked T waves can be a sign of hyperkalemia or very early myocardial ...

    The flu is ramping up after a slow start to the season. Positive tests rose 12% for the week ending Dec. 21, compared to the week prior, according to data released Friday by the Centers for ...

  8. Pulmonary embolism - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_embolism

    Electrocardiogram of a person with pulmonary embolism, showing sinus tachycardia of approximately 100 beats per minute, large S wave in Lead I, moderate Q wave in Lead III, inverted T wave in Lead III, and inverted T waves in leads V1 and V3. The primary use of the ECG is to rule out other causes of chest pain. [72]
