  2. Hyperkalemia - Wikipedia

    en.wikipedia.org/wiki/Hyperkalemia

    ECG findings are not a reliable finding in hyperkalemia. In a retrospective review, blinded cardiologists documented peaked T-waves in only 3 of 90 ECGs with hyperkalemia. Sensitivity of peaked-Ts for hyperkalemia ranged from 0.18 to 0.52 depending on the criteria for peak-T waves. [medical citation needed]

    en.wikipedia.org/wiki/Short_QT_syndrome

    The mainstay of diagnosis of short QT syndrome is the 12-lead ECG. The precise QT duration used to diagnose the condition remains controversial with consensus guidelines giving cutoffs varying from 330 ms, [ 12 ] 340 ms or even 360 ms when other clinical, familial, or genetic factors are present.

  4. T wave - Wikipedia

    en.wikipedia.org/wiki/T_wave

    Ischemic T waves rise and then fall below the cardiac resting membrane potential; Hypokalemic T waves fall and then rise above the cardiac resting membrane potential; Wellens' Syndrome is a pattern of biphasic T waves in V2–3. It is generally present in patients with ischemic chest pain. Type 1: T-waves are symmetrically and deeply inverted

  5. Electrocardiography - Wikipedia

    en.wikipedia.org/wiki/Electrocardiography

    The earliest sign is hyperacute T waves, peaked T waves due to local hyperkalemia in ischemic myocardium. This then progresses over a period of minutes to elevations of the ST segment by at least 1 mm. Over a period of hours, a pathologic Q wave may appear and the T wave will invert. Over a period of days the ST elevation will resolve.

    The diagnosis of hypokalemia (not enough potassium) can be suspected when there is a history of diarrhoea or malnutrition. Loop diuretics may also contribute. The electrocardiogram may show flattening of T waves and prominent U waves. Hypokalemia is an important cause of acquired long QT syndrome, and may predispose the patient to torsades de ...

    Schwartz score to aid diagnosis of inherited long QT syndrome. [37] Corrected QT interval (QTc) ≥ 480 ms 3 points QTc defined according to Bazett's correction: 460–470 ms 2 points 450 ms and male gender 1 point Torsades de pointes: 2 points T-wave alternans: 1 point Notched T-waves in at least 3 leads 1 point Low heart rate for age (children)

  8. Chronic kidney disease - Wikipedia

    en.wikipedia.org/wiki/Chronic_kidney_disease

    The T-waves are peaked and the QT interval is prolonged. Diagnosis of CKD is largely based on history, examination, and urine dipstick combined with the measurement of the serum creatinine level. Differentiating CKD from acute kidney injury (AKI) is important because AKI can be reversible. One diagnostic clue that helps differentiate CKD from ...

    en.wikipedia.org/wiki/Ectopic_pacemaker

    During atrial ectopic activity where the P wave is normally rounded can be inverted or peaked. However the QRS complex and T waves appear relatively normal. [ 10 ] Conversely, during junctional ectopic activity the P wave is frequently absent or can be hidden in the QRS complex.
