Low-Voltage Electrocardiogram: Causes & Reasons

Possible Causes for Low-Voltage Electrocardiogram

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 [ncbi.nlm.nih.gov]

The electrocardiogram (Fig. 2) revealed a diphasic T,; T, was inverted. QRS, was of low voltage, and S, was prominent. [kundoc.com]

Electrocardiogram demonstrated sinus rhythm ( n = 30), low voltage QRS complex ( n = 30), flattening or T-wave inversion ( n = 29), and premature ventricular contraction [annals.in]

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 [ncbi.nlm.nih.gov]

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]

Restrictive Cardiomyopathy

A low voltage electrocardiogram (ECG) and increased wall thickness with abnormal texture on echocardiography are the classic findings. [acc.org]

We present a 62-year-old with a history of heart failure, which in its assessment highlights the discrepancy between the low voltage ventricular complexes in the electrocardiogram [ncbi.nlm.nih.gov]

And then, a provider may also get an electrocardiogram, or an ECG, and this is going to show low voltage QRS complexes. [khanacademy.org]

Cardiac Tamponade

The electrocardiogram showed low-voltage QRS complex with electrical alternans. [ncbi.nlm.nih.gov]

which may also show low voltage QRS complexes, as well as general signs and symptoms of shock (such as fast heart rate, shortness of breath and decreasing level of consciousness [en.wikipedia.org]

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]

Amyloidosis

Systemic amyloidosis (AA) can lead to heart failure with left ventricular hypertrophy on echocardiogram with standard or low voltage electrocardiogram. [ncbi.nlm.nih.gov]

Left ventricular hypertrophy, low-voltage electrocardiogram, and restrictive cardiomyopathy are some of the cardiac manifestations (77. Cueto-Garcia L, et al. [acphospitalist.org]

In both cases, an electrocardiogram revealed low-voltage sinus rhythm. [revistanefrologia.com]

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 [ncbi.nlm.nih.gov]

Radiography of the chest generally shows cardiomegally and the electrocardiogram may show arrhythmias, heart block, low voltage and T wave abnormalities. [heartviews.org]

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]

Pericardial Effusion

Figure 1 Electrocardiogram showing low QRS voltage. Figure 2 Chest X ray showing "water bottle sign" (black arrow) suggestive of a large pericardial effusion. [acc.org]

Initial workup will include an electrocardiogram which may show: Low voltage Electric alterans A chest X-ray may show an enlarged globular heart. [symptoma.com]

The electrocardiogram showed sinus tachycardia and low voltage. [rjmatthewsmd.com]

Myocardial Fibrosis

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

Malignant Pericardial Effusion

Prominent low voltage QRS complexes in all derivations were obtained on electrocardiogram (Figure 1). [ispub.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]

Figure 1 Figure 1: Noted tachycardia and low voltage criteria in all derivations on the ECG strip of the patient. [ispub.com]

Myxedema

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

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]

Addison Disease

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

Hemopericardium

Electrocardiograms in cardiac tamponade may show low-amplitude QRS complexes signifying low voltage, or in up to 10–20% of cases may reveal the more specific finding of electrical [ncbi.nlm.nih.gov]

Tuberculous Pericarditis

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

Congenital Non-Goitrous Hypothyroidism Type 4

Bradycardia is noticed in some patients, and the electrocardiogram (ECG) may show a low voltage with nonspecific ST abnormalities. [glowm.com]

Pneumothorax

Overview A pneumothorax (noo-moe-THOR-aks) is a collapsed lung. A pneumothorax occurs when air leaks into the space between your lung and chest wall. This air pushes on the outside of your lung and makes it collapse. A pneumothorax can be a complete lung collapse or a collapse of only a portion of the lung. A[…] [mayoclinic.org]
