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 [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]

Myocardial Fibrosis

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

Pericardial Effusion

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]

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]

Tuberculous Pericarditis

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

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]

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]

Chronic Alcoholism

The concept of "structural plasticity" has emerged as a potential mechanism in neurodegenerative and psychiatric diseases such as drug abuse, depression, and dementia. Chronic alcoholism is a progressive neurodegenerative disease while the person continues to abuse alcohol, though clinical and imaging studies show[…] [ncbi.nlm.nih.gov]

Chronic Obstructive Pulmonary Disease

Summary COPD (chronic obstructive pulmonary disease) makes it hard for you to breathe. The two main types are chronic bronchitis and emphysema. The main cause of COPD is long-term exposure to substances that irritate and damage the lungs. This is usually cigarette smoke. Air pollution, chemical fumes, or dust can[…] [medlineplus.gov]

Angina Pectoris

You may have heard the term “angina pectoris” or “stable angina” in your doctor’s office, but what is it, and what could it mean for you? It’s important to understand the basics. Angina pectoris is the medical term for chest pain or discomfort due to coronary heart disease. It occurs when the heart muscle[…] [heart.org]

Coronary Atherosclerosis

Coronary artery disease (CAD) exhibits the rules of the multifactorial hereditary. Notwithstanding, the role of genetic factors in the prevalence of CAD is estimated very high. SIRT1 plays an athero-protective role and alterations in its expression have some important consequence in the metabolism, cholesterol, and[…] [ncbi.nlm.nih.gov]

Myocardial Infarction

Myocardial infarction, commonly referred to as heart attack, is a condition characterized by necrosis of the heart muscles due to development of ischemia that stays on for prolonged periods. Such a condition develops when the heart does not receive oxygen and blood due to blockage in the coronary arteries.[…] [symptoma.com]

Acute Myocardial Infarction

We herein report the case of a 25-year-old Japanese woman with left-main-trunk acute myocardial infarction (LMT-AMI). She had cardiogenic shock, so emergency percutaneous intervention was performed.

Pneumothorax

Abstract Jean-Marc Gaspard Itard, a student of René Laennec's, first recognized pneumothorax in 1803, and Laennec himself described the full clinical picture of the condition in 1819. Treatment of pneumothorax was not begun as a standard procedure until World War II, but we think that Serefeddin Sabuncuoglu[…] [ncbi.nlm.nih.gov]

Ischemic Cardiomyopathy

Because of the shortage of donor hearts, 16 (33%) of 48 patients with ischemic cardiomyopathy died awaiting transplantation. Determining factors that predict effective coronary revascularization and identifying patients who may benefit from revascularization is crucial. From 1984 to 1990, 207 ischemic cardiomyopathy[…] [ncbi.nlm.nih.gov]

Hydropericardium

Two outbreaks of severe acute disease characterised by hepatitis and hydropericardium were observed in young goslings on large-scale farms in Hungary.
