316 Possible Causes for Abnormal ECG, Dizziness, Hypoxemia

  • Heart Failure

    Dizziness, fatigue, and weakness. Less blood to your major organs and muscles makes you feel tired and weak. Less blood to the brain can cause dizziness or confusion.[] These SRDB cause arousals, hypoxemia-reoxygenation, hypercapnia-hypocapnia, and changes in intrathoracic pressure.[] A 65-year-old gentleman presented with an acute right middle cerebral artery territory infarction, and was found to have ECG abnormalities and left ventricular dysfunction[]

  • Congestive Heart Failure

    While symptoms of heart failure vary by person, swelling of the legs, irregular heartbeats or other unexplained symptoms like shortness of breath or dizziness could be early[] These SRDB cause arousals, hypoxemia-reoxygenation, hypercapnia-hypocapnia, and changes in intrathoracic pressure.[] Interatrial block is an abnormally delayed atrial activation, characterized at ECG by prolonged P-wave duration (more than 110 ms), irrespective of morphology.[]

  • Atrial Fibrillation

    We report a previously healthy 58-years old female, admitted because of nausea, dizziness, somnolence, a left-sided hemiparesis and arterial hypotension.[] Pulmonary Diseases Class I Correction of hypoxemia and acidosis is the recommended primary therapeutic measure for patients who develop AF during an acute pulmonary illness[] At the same time, the harms of diagnostic follow-up and treatment prompted by abnormal ECG results are well established and include misdiagnosis and invasive testing.[]

  • Tachyarrhythmia

    A 31-year-old female presented with atypical chest pain, palpitations, tachycardia, headaches, and dizziness for 2 years.[] Goal should be to identify and rectify this condition (ex. hypoxemia, sepsis, hypovolemia, pharmacology).[] However, an incidental discovery of an abnormal ECG without symptoms or family history may not necessarily imply syndrome phenotype.[]

  • Pulmonary Arterial Hypertension

    Shortness of breath, dizziness, and chest pressure are common symptoms of PAH.[] Of them, 143 (49%) had SpO2 90% at rest and during 6MWT, 89 (31%) subjects had hypoxemia during 6MWT and 60 (20%) had hypoxemia at rest.[] An ECG may show some abnormalities that may be suggestive of right heart failure. Chest x-ray may also show enlargement of the chambers of the right heart.[]

  • Syncope

    They could present with the following: Dizziness (vertigo) or lightheadedness Weakness Loss of consciousness Tunnel vision Pale or sweaty skin Decreased or weak pulse How[] Other causes of transient loss of consciousness need to be distinguished from syncope; these include seizures, vertebrobasilar ischemia, hypoxemia, and hypoglycemia.[] An abnormal ECG was predictive of an abnormal ECHO (p 0.02).[]

  • Chronic Thromboembolic Pulmonary Hypertension

    Heart palpitations or fluttering Dry cough Swelling of the lower extremities or stomach (edema) As the disease progresses, symptoms of light-headedness or exercise-related dizziness[] His preoperative examination revealed severe hypoxemia (PaO2 48 mmHg, PaCO2 34 mmHg in room air), a mass in the right ventricle and severe pulmonary hypertension (pulmonary[] AEs were mainly mild to moderate in nature and the most common were headache and dizziness.[]

  • Pulmonary Edema

    Associated symptoms included cough, weakness, expectoration of froth, chest discomfort, orthopnea, wheezing, hemoptysis, and dizziness.[] Failure to decompress the left heart under these circumstances can result in pulmonary edema and upper body hypoxemia, that is, myocardial and cerebral ischemia.[] […] fluid blood tests to check oxygen levels electrocardiogram (ECG) to look for heart rhythm problems or signs of a heart attack Pulmonary edema is a serious condition that[]

  • Acute Hyperventilation

    Presenting complaints were dyspnea (61%), paresthesia (35%), chest pain or tightness (43%), muscle spasm (9%), dizziness (13%), palpitations (13%), and panic (30%).[] Moderate hypoxemia of 51 mm Hg indicates this is a ventilatory problem.[] Electrocardiographic (ECG) changes are common in patients with HVS. Abnormalities may include prolonged QT interval, ST depression or elevation, and T-wave inversion.[]

  • Pulmonary Embolism

    The patient's dizziness improved in ED. Neurological examination returned to base line status but sinus tachycardia and low saturation value on room air were continuing.[] Concurrent persistent hypoxemia should be a clue to the existence of an intracardiac shunt.[] In not high-risk patients, the presence of at least one ECG abnormality was significantly associated with RVD and this association was confirmed for each individual ECG abnormality[]
