Myxoedema coma • This is the admission ECG of a 79-year old man who was referred to ICU with coma, hypothermia, severe bradycardia and hypotension refractory to inotropes. • TSH was markedly elevated with an undetectable T4. • The ECG shows marked bradycardia (30 bpm) with low QRS voltages (esp. in the limb leads) and widespread T-wave inversions, typical of severe myxoedema. Myxoedema coma (after treatment) • An ECG of the same patient shortly after initiation of thyroid replacement with intravenous T3 and T4. • The heart rate has normalised and the T-wave inversion has corrected. • Low voltage in the limb leads persists and is likely due to myxoedematous infiltration of the myocardium.

Abstract The interpretation of 12-lead resting electrocardiogram (ECG) in patients with a definitive diagnosis or with the suspicion of a cardiomyopathy represents a cornerstone for the diagnostic work up and management of patients. Although low electrocardiographic QRS voltages (LQRSV) detected by 12-lead resting ECG have historically been acknowledged by physicians, in view of recent evidence on the demonstration of myocardial scar by cardiac magnetic resonance and its relevance as a cause of sudden cardiac death even in young individuals, a new interest has been raised about the utility of LQRSV in the clinical practice. Beyond their diagnostic value, LQRSV have also demonstrated a prognostic role in different cardiomyopathies. The present review summarizes the diagnostic and prognostic value of LQRSV in cardiomyopathies, reporting the new evidence, primarily based on advanced imaging studies, supporting the clinical utility of this parameter.

Although commonly used to assess myocardial ischemia and dysrhythmias, the ECG is also capable of detecting electrolyte abnormalities and fluid overload in critically ill patients. This case study describes the clinical presentation of an adult female with a complex medical history who presented to the ED for worsening fatigue and high ileostomy output. Her hospitalization was complicated by acute fluid overload—detected by ECG—after aggressive I.V. rehydration. This article provides a detailed description of the clinical case and a deeper understanding of the effects of fluid and electrolyte abnormalities on the ECG. Patient information A 68-year-old female with a chief complaint of increasing fatigue, poor appetite, and increased ileostomy output over the last 2 weeks presented to the ED...

Key Points • • • • In patients with acute PE, anterior T-wave inversions, an rSR’ complex in V1 and acute right axis deviation are markers of acute pulmonary hypertension and right heart strain. They are associated with more severe pulmonary hypertension, right ventricular dysfunction, extensive pulmonary vascular obstruction (clot burden) and mortality. • • Some patients develop a focal myocarditis; here, the ECG may show ST-segment elevations in a regional pattern (for example, suggesting inferior wall STEMI). Acute myocarditis is a “don’t-miss” diagnosis because patients may develop fulminant congestive heart failure or malignant ventricular arrhythmias. • • There are dozens of causes of shortness of breath; in most cases, the diagnosis does not depend on the electrocardiogram. Pneumonia, asthma, emphysema, congestive heart failure, upper airway obstruction and other common conditions are usually evident after performing a careful history and physical examination. At the same time, there are at least three common “shortness of breath emergencies” – pulmonary thromboembolism, pericardial effusion and myocarditis – where the ECG often provides the first diagnostic information. The ECG is not the definitive test for any of these conditions; in terms of “diagnostic test characteristics” (sensitivity and specificity), the ECG may perform poorly. However, the ECG is often the first test performed. In many cases, the ECG provides unmistakable clues to these critical conditions...

I HAD AN EKG TODAY AND WAS TOLD I HAD LOW VOLTAGE. I WAS AT A WEIGHT LOSS CLINIC. I HAVE RESEARCHED AND FOUND THERE CAN BE MANY CAUSES (HYPOTHYROIDISM, OBESITY) AND SEVERAL OTHER REALLY SCARY ONES SUCH AS AMYLORDOSIS, SCLERADERMA. I'M TOTALLY FREAKED OUT. I'M 43 AND NEED TO LOOSE 45LBS. IS THIS A SIGNIFICANT AMOUNT OF WEIGHT TO CAUSE LOW VOLTAGE? I HAVE HYPOTHYROIDISM AND TAKE MEDICATION - COULD THIS STILL BE A POSSIBLE CAUSE. WHAT IS THE LONG TERM AFFECT ON MY HEART AND WILL MY VOLTAGE EVER RETURN TO NORMAL IF LOOSE WEIGHT OR MEDICATION ADJUSTMENT? DO I NEED WORRY ABOUT SUDDEN DEATH? I HAVE AN APPOINTMENT WITH MY PRIMARY DR IN A WEEK. I'M AFRAID TO FALL ASLEEP....THANKS low voltage ecg is just that, the equipment is receiving much fainter voltages than normal. There can be many reasons for this and the reason has to be issued with the ecg report. For example, it can be due to obesity, the heart is further from the sensors. It can be over inflated lungs and it can be through heart disease. SO, with such diverse reasons, one would only be guessing and the reason has to be stated by the operator at the time the ecg was taken. Hello, I just found your post from last year.Today is 9.13.09.I could not find any "answer" to your posted question.Can you provide any update information about what happened to you? I have doctors all ignoring my Low Voltage on my ECG also.I have atrial fibrillation, also.I am thinking there are multiple causes, including my kidney disease. I have been...
