  2. Hypokalemia - Wikipedia

    en.wikipedia.org/wiki/Hypokalemia

    Hypokalemia is a low level of potassium (K +) in the blood serum. [1] Mild low potassium does not typically cause symptoms. [3] Symptoms may include feeling tired, leg cramps, weakness, and constipation. [1] Low potassium also increases the risk of an abnormal heart rhythm, which is often too slow and can cause cardiac arrest. [1] [3]

  3. U wave - Wikipedia

    en.wikipedia.org/wiki/U_wave

    According to V. Gorshkov-Cantacuzene: "The U wave is the momentum carried by the blood in the coronary arteries and blood vessels". [4] [5] [6]The resistivity of stationary blood is expressed as () = | (+), where is a coefficient, and is the hematocrit; at that time, as during acceleration of the blood flow occurs a sharp decrease in the longitudinal resistance with small relaxation times.

  4. Trans-tubular potassium gradient - Wikipedia

    en.wikipedia.org/wiki/Trans-tubular_potassium...

    The trans-tubular potassium gradient (TTKG) is an index reflecting the conservation of potassium in the cortical collecting ducts (CCD) of the kidneys.It is useful in diagnosing the causes of hyperkalemia or hypokalemia.

  5. Electrocardiography - Wikipedia

    en.wikipedia.org/wiki/Electrocardiography

    Electrocardiography is the process of producing an electrocardiogram (ECG or EKG [a]), a recording of the heart's electrical activity through repeated cardiac cycles. [4] It is an electrogram of the heart which is a graph of voltage versus time of the electrical activity of the heart [ 5 ] using electrodes placed on the skin.

  6. P wave (electrocardiography) - Wikipedia

    en.wikipedia.org/wiki/P_wave_(electrocardiography)

    Peaked P waves (> 0.25 mV) suggest right atrial enlargement, cor pulmonale, (P pulmonale rhythm), [1] but have a low predictive value (~20%). [2] A P wave with increased amplitude can indicate hypokalemia. [3] It can also indicate right atrial enlargement. [4] A P wave with decreased amplitude can indicate hyperkalemia. [5]

  7. Electrolyte imbalance - Wikipedia

    en.wikipedia.org/wiki/Electrolyte_imbalance

    Low potassium is caused by increased excretion of potassium, decreased consumption of potassium rich foods, movement of potassium into the cells, or certain endocrine diseases. [3] Excretion is the most common cause of hypokalemia and can be caused by diuretic use, metabolic acidosis , diabetic ketoacidosis , hyperaldosteronism , and renal ...

  8. Hyperkalemia - Wikipedia

    en.wikipedia.org/wiki/Hyperkalemia

    Initial treatment in those with ECG changes is salts, such as calcium gluconate or calcium chloride. [1] [3] Other medications used to rapidly reduce blood potassium levels include insulin with dextrose, salbutamol, and sodium bicarbonate. [1] [5] Medications that might worsen the condition should be stopped and a low potassium diet should be ...
