78 Possible Causes for Dehydration, Flattened T Waves (ECG)

Did you mean: Dehydration, Flattened T Waves (ECG

  • Adrenal Insufficiency

    CASE PRESENTATION: The proposita, 11 months old of age, was admitted for lethargy and severe dehydration.[] If potassium is above 7.0 mmol/L and hyperkalaemic ECG changes are present (eg. peaked T waves wide QRS complex flattened P waves), treat with either of the following: give[] Complications occurred in 61 cases (67.0 %): asthenia in 88.5 % of cases, intense thirst in 32.8 %, symptoms of dehydration in 49.2 % and symptoms of hypoglycaemia in 18 %[]

  • Electrolyte Imbalance

    Be aware of treatment measures for dehydration and electrolyte imbalance. Dehydration Increase fluids of any kind.[] Clinical signs of hyperkalaemia include muscle weakness, hypotension , bradycardia and loss of cardiac output, and ECG changes may include peaked T waves and flattened P waves[] There is an intrinsic link between chronic hypertension, renal failure, dehydration and a deficiency of certain electrolyte minerals.[]

  • Hypercalcemia

    Evidence of dehydration, hypercalciuria, and nephrocalcinosis were common in both groups.[] At very high serum calcium levels ECG changes include slight prolongation of the PR and QRS intervals, T wave flattening or inversion, and the appearance of a J wave at the[] On physical examination, we observed tachycardia, altered mental status, and dehydration.[]

  • Salicylate Poisoning

    Hyperventilation (P less than .01), dehydration (P less than .001), and severe central nervous system manifestations (P less than .001) occurred more frequently in the chronic[] ) abnormalities - Eg, U waves, flattened T waves, QT prolongation; may reflect hypokalemia 16.[] Other blood chemistry changes are dehydration, hypokalemia, and hypocalcemia.[]

  • Accidental Hypothermia

    Regular consumption of high-energy food rich in carbohydrates aids the body in heat production, while 13-17 c (3-4L) of water a day prevents rapid dehydration from evaporation[] The ECG manifestations of hyperkalemia begin with peaked T waves.[] In hypercalcemia, the ECG shows a shortened QT interval, flattened T waves and QRS widening at very high levels. 4. Atrial fibrillation.[]

  • Laxative Abuse

    Further urine studies include urine volume and electrolytes to determine the volume status and the degree of dehydration.[] ECG revealed sinus rhythm with a left axis deviation, T-wave flattening but no U waves. Renal ultrasound showed normal sized kidneys with no evidence of hydronephrosis.[] , so others may need to seek emergency help for them if they are severely dehydrated.[]

  • Distal Renal Tubular Acidosis

    The levels of both serum calcium and ammonia rapidly normalized with the correction of dehydration and metabolic acidosis.[] ., muscle weakness, hyporeflexia, paralysis, U waves and flattened T waves on ECG ) Autosomal recessive causes of type 1 RTA may present with sensorineural deafness.[] RESULTS: Two cases with primary distal renal tubular acidosis were found, and they had a history of dehydration episodes during infancy and showed hyperchloremic metabolic[]

  • Diabetic Ketoacidosis

    […] to those with mild dehydration).[] An ECG can be of help in monitoring the patient's potassium status: High peaked T waves are a sign of hyperkalemia, and flattened T waves with U waves are a sign of hypokalemia[] Additionally, fluid therapy in amounts concordant with the degree of dehydration remains the mainstay therapy.[]

  • Acute Kidney Failure

    People who are dehydrated or at risk of dehydration may need to be given fluids through a drip.[] ECG revealed sinus rhythm with a left axis deviation, T-wave flattening but no U waves. Renal ultrasound showed normal sized kidneys with no evidence of hydronephrosis.[] Dehydration caused by drastically reduced fluid intake or excessive use of diuretics (water pills) is a major cause of prerenal ARF.[]

  • Lithium Toxicity

    Early in her admission she was dehydrated and had febrile episodes, paroxysmal atrial fibrillation, and muscle weakness.[] Cardiologic signs and symptoms appear in only 20%–30% of patients. 3 The most frequent ECG findings are T wave changes (i.e. flattening).[] Its adverse effects of dehydration and serum electrolyte imbalances are widely known.[]
