422 Possible Causes for Low-Voltage Electrocardiogram

  • Cardiac Amyloidosis

    On the electrocardiogram, however, there are no signs of LV hypertrophy and the recorded voltage is low.[esciencecentral.org] Electrocardiogram (ECG) revealed sinus rhythm, low voltages in limb leads, QS waves in precordial and inferior leads, first-degree atrioventricular block, and prolonged QTc[dovepress.com] Figure 2 Typical Appearance of the Electrocardiogram in Cardiac Amyloidosis There is low voltage with lateral T-wave inversion and poor R-wave progression in the precordial[content.onlinejacc.org]

  • Cardiac Tamponade

    An electrocardiogram revealed sinus tachycardia and low voltages, and chest radiography demonstrated the presence of severe right PE and contralateral mediastinal shift (Figure[revespcardiol.org] , [14] which may also show low voltage QRS complexes , [10] as well as general signs and symptoms of shock (such as fast heart rate , shortness of breath and decreasing level[en.wikipedia.org] Low voltage.[drnajeeblectures.com]

  • Myxedema

    However, the MB fraction in most of these cases is normal, and an electrocardiogram (ECG) often demonstrates bradycardia, low voltage, and loss of T waves that is characteristic[endocrinologyadvisor.com] Body temperatures as low as 23.3 C have been reported; thus, rectal temperatures are essential to making the diagnosis.[endocrinologyadvisor.com] In the patient with central hypothyroidism, the diagnosis of myxedema coma maybe very difficult, as serum TSH concentrations will be normal or low.[endocrinologyadvisor.com]

  • Pericardial Effusion

    The presence of increased pericardial fluid may partially explain the decreased voltage on the electrocardiogram, and the distant heart sounds heard in some of these patients[link.springer.com] Low QRS voltages on ECG.[escardio.org] Electrocardiogram (ECG) ECG may show small voltage in the precordial and limb leads.[iame.com]

  • Systemic Amyloidosis

    Electrocardiogram (ECG) showed sinus tachycardia, low QRS voltage and a Q-wave in precordial leads V1–V4.[bjcardio.co.uk] The patient's history of pulmonary hypertension and low-voltage QRS complex on electrocardiogram were consistent with cardiac amyloid infiltration and resultant restrictive[cutis.com] Electrocardiogram showed frequent multifocal ventricular premature beats and low voltage.[omicsonline.org]

  • Ischemic Cardiomyopathy

    Endocardial and epicardial radiofrequency ablation of ventricular tachycardia associated with dilated cardiomyopathy: The importance of low-voltage scars.[innovationsincrm.com] […] with increased myocardial wall thickness, particularly biventricular thickening, should arouse suspicion of an infiltrative cardiomyopathy, especially if accompanied by low-voltage[clevelandclinicmeded.com] Substrate Our assessment of the arrhythmia substrate begins with the 12-lead electrocardiogram (ECG).[innovationsincrm.com]

  • Restrictive Cardiomyopathy

    Electrocardiogram: ECG changes are nonspecific.[wikiecho.org] It may also show low signals (called “low voltage”).[nlm.nih.gov] Electrocardiogram The P waves in constrictive pericarditis tend to be wide and notched, but low in amplitude, reflecting intra-atrial conduction delay.[heart.bmj.com]

  • Acute Myocarditis

    Radiography of the chest generally shows cardiomegally and the electrocardiogram may show arrhythmias, heart block, low voltage and T wave abnormalities.[heartviews.org] […] changes, low voltage QRS complexes, axis deviation and ventricular hypertrophy. 2 Infarction patterns, atrial abnormalities and various degrees of heart block may also be[jpma.org.pk] The 12-lead electrocardiogram (ECG) is used widely in the diagnosis of myocarditis despite low sensitivity. 5,19 The most common ECG changes are sinus tachycardia, S-T wave[jpma.org.pk]

  • Malignant Pericardial Effusion

    Prominent low voltage QRS complexes in all derivations were obtained on electrocardiogram (Figure 1).[ispub.com] Diagnosis Electrocardiography The ECG does not show specific findings, but low voltage may be seen.[clevelandclinicmeded.com] Due to cardiac relaxation limitations, the patient presents congested jugular veins, tachycardia, arrhythmia, and low voltage criteria on electrocardiograms ( 1 , 3 , 7 ).[ispub.com]

  • Cardiomyopathy

    […] with increased myocardial wall thickness, particularly biventricular thickening, should arouse suspicion of an infiltrative cardiomyopathy, especially if accompanied by low-voltage[clevelandclinicmeded.com] Stress cardiomyopathy can mimic an acute MI but has recognizable electrocardiogram (ECG) and angiographic features.[clevelandclinicmeded.com] Endomyocardial biopsy may show findings specific for sarcoidosis but because of the patchy nature of the disease biopsy can miss characteristic lesions, resulting in a low[clevelandclinicmeded.com]
