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

  • Hypercalcemia

    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[ncbi.nlm.nih.gov] Evidence of dehydration, hypercalciuria, and nephrocalcinosis were common in both groups.[ncbi.nlm.nih.gov] On physical examination, we observed tachycardia, altered mental status, and dehydration.[ncbi.nlm.nih.gov]

  • Adrenal Insufficiency

    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[rch.org.au] The proposita, 11 months old of age, was admitted for lethargy and severe dehydration.[ncbi.nlm.nih.gov] 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 %[ncbi.nlm.nih.gov]

  • Accidental Hypothermia

    The ECG manifestations of hyperkalemia begin with peaked T waves.[foamcast.org] 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[science.jrank.org] […] mean arterial pressure, cardiac output, and myocardial contractility-all of which may remain low until the patient is normothermic. 10 In moderate and severe hypothermia, dehydration[nursingcenter.com]

  • Distal Renal Tubular Acidosis

    ., muscle weakness, hyporeflexia, paralysis, U waves and flattened T waves on ECG ) The autosomal recessive form of type 2 RTA may be associated with glaucoma , cataracts[amboss.com] The levels of both serum calcium and ammonia rapidly normalized with the correction of dehydration and metabolic acidosis.[ncbi.nlm.nih.gov] Two cases with primary distal renal tubular acidosis were found, and they had a history of dehydration episodes during infancy and showed hyperchloremic metabolic acidosis[ncbi.nlm.nih.gov]

  • Digoxin

  • Pericarditis

    The inflammation, pain, dehydration and fatigue due to pericarditis and stress increases the patient’s overall stress level, which worsens the symptoms of diabetes.[pericarditispain.info] Stage II: ST segment elevation and PR depression have resolved and T waves may be normal or flattened. Stage III: T waves are inverted, and the ECG is otherwise normal.[healio.com] At first I thought I was dehydrated, but a few temperature readings confirmed that I had a low-grade fever.[healdove.com]

  • Renal Tubular Acidosis

    ., muscle weakness, hyporeflexia, paralysis, U waves and flattened T waves on ECG ) The autosomal recessive form of type 2 RTA may be associated with glaucoma , cataracts[amboss.com] Two cases with primary distal renal tubular acidosis were found, and they had a history of dehydration episodes during infancy and showed hyperchloremic metabolic acidosis[ncbi.nlm.nih.gov] […] patient with growth retardation, pRTA, and ocular abnormalities, but also showed anemia, volume depletion, prerenal azotemia, and several organ abnormalities, culminating in dehydration[ncbi.nlm.nih.gov]

  • Lithium Toxicity

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

  • Torsades De Pointes

    Common causes for Torsades de Pointes include electrolyte imbalances, which may be a result of diarrhea, vomiting, dialysis and dehydration.[alivecor.com.hk] In ECGs with flattened or complex T waves, physicians should compare the QT intervals on several leads, using a caliper for accuracy.[thecardiologyadvisor.com] Limb lead II or precordial lead V5 are recommended for measurement of the QT interval unless T waves are not discernible in these two leads.[thecardiologyadvisor.com]

  • Hypokalemia
