131 Possible Causes for Low-Voltage Electrocardiogram

  • Chronic Constrictive Pericarditis

    Negative predictors of survival were found to be preoperative NYHA class IV (P 0.01), low-voltage electrocardiogram (ECG) (P 0.01), ascites (P 0.01), dyspnea at rest (P 0.05[] The electrocardiogram (Fig. 2) revealed a diphasic T,; T, was inverted. QRS, was of low voltage, and S, was prominent.[] Electrocardiogram demonstrated sinus rhythm ( n 30), low voltage QRS complex ( n 30), flattening or T-wave inversion ( n 29), and premature ventricular contraction ( n 3).[]

  • Restrictive Cardiomyopathy

    A low voltage electrocardiogram (ECG) and increased wall thickness with abnormal texture on echocardiography are the classic findings.[] And then, a provider may also get an electrocardiogram, or an ECG, and this is going to show low voltage QRS complexes.[]

  • Myocardial Fibrosis

    An electrocardiogram showed low voltage and a pseudo-infarctional pattern in leads V1 through V3.[]

  • Addison's Disease

    An electrocardiogram showed sinus tachycardia, low voltage, negative T-waves in V5 and V6 and a corrected QT interval of 590 ms.[]

  • Tuberculous Pericarditis

    An electrocardiogram showed sinus tachycardia and low-voltage complexes in the limb and precordial leads.[]

  • Acute Myocarditis

    Arrhythmias were associated with low voltages on the electrocardiogram (14 of 34, 41% vs 6 of 47, 13%; odds ratio [OR] 4.78, 95% confidence interval [CI] 1.60 to 14.31) and[] Radiography of the chest generally shows cardiomegally and the electrocardiogram may show arrhythmias, heart block, low voltage and T wave abnormalities.[] 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[]

  • Systemic Amyloidosis

    In all cases, electrocardiogram showed low voltage in the limb leads and a pseudoinfarct pattern in the chest leads, and echocardiography showed left ventricular wall thickening[] […] settings, including nephrotic syndrome with albuminuria rather than Bence Jones proteinuria, peripheral or autonomic neuropathy, diastolic heart failure with normal- or low-voltage[] The patient's history of pulmonary hypertension and low-voltage QRS complex on electrocardiogram were consistent with cardiac amyloid infiltration and resultant restrictive[]

  • Malignant Pericardial Effusion

    Prominent low voltage QRS complexes in all derivations were obtained on electrocardiogram (Figure 1).[] The electrocardiogram (ECG) showed low voltage and alternating electrical heart axis.[] Due to cardiac relaxation limitations, the patient presents congested jugular veins, tachycardia, arrhythmia, and low voltage criteria on electrocardiograms ( 1 , 3 , 7 ).[]

  • Cardiac Amyloidosis

    Electrocardiogram depicted low voltage in limb leads and a prolonged PR interval.[] On the electrocardiogram, however, there are no signs of LV hypertrophy and the recorded voltage is low.[] Electrocardiogram revealed a normal sinus rhythm at a rate of 110 beats per minute and low voltage complexes ( Figure 1 ).[]

  • Myxedema

    Electrocardiogram (ECG) reveals low voltage, T wave abnormalities.[] 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[]
