What is McGinn-White Sign?
The McGinn-White Sign is the S1Q3T3 pattern seen on the ECG in the setting of acute pulmonary embolism or other causes of acute right heart strain (cor pulmonale).
What is the S1Q3T3 ECG pattern?
However, the “S1Q3T3” pattern of acute cor pulmonale is classic; this is termed the McGinn-White Sign. Enlarge. A large S wave in lead I, a Q wave in lead III and an inverted T wave in lead III together indicate acute right heart strain.
What causes S1Q3T3?
Other common pathological conditions which can cause S1Q3T3 electrocardiographic abnormality are pneumothorax, pulmonary embolism, cor pulmonale, acute lung disease, and left posterior fascicular block.
What is Hamptons hump?
Hampton’s hump is a radiological sign consisting of a peripheral, wedge-shaped opacification adjacent to the pleural surface, which represents pulmonary infarction distal to a pulmonary embolus. 1. Owing to good pulmonary perfusion from collateral blood vessels, this sign is rarely seen in clinical practice.
What is Pulmonale?
Cor pulmonale is a condition that happens when a respiratory disorder results in high blood pressure in the pulmonary arteries (pulmonary hypertension). The name of the condition is in Latin and means “pulmonary heart.”
What is a Hampton’s hump?
What is cor pulmonale definition?
Cor pulmonale is a condition that causes the right side of the heart to fail. Long-term high blood pressure in the arteries of the lung and right ventricle of the heart can lead to cor pulmonale.
How sensitive is S1Q3T3 for a PE?
The classic S1Q3T3 pattern is described to be present only in 20 % of cases, Ferrari et al (3) found that this pattern had a sensitivity of 54% and a specificity of 62%.
What is Plethoric lung fields?
Plethoric lung fields are indicative of increased pulmonary blood flow and are seen in left-to-right shunts. The pulmonary artery branches are prominently seen up to peripheral lung fields and flow is significantly increased.
What is pulmonary Oligemia?
In chest radiography, the Westermark sign is a sign that represents a focus of oligemia (hypovolemia) (leading to collapse of vessel) seen distal to a pulmonary embolism (PE). While the chest x-ray is normal in the majority of PE cases, the Westermark sign is seen in 2% of patients.
Whats is CF?
Cystic fibrosis (CF) is an inherited disorder that causes severe damage to the lungs, digestive system and other organs in the body. Cystic fibrosis affects the cells that produce mucus, sweat and digestive juices. These secreted fluids are normally thin and slippery.
What Orthopnea means?
Orthopnea is the sensation of breathlessness in the recumbent position, relieved by sitting or standing. Paroxysmal nocturnal dyspnea (PND) is a sensation of shortness of breath that awakens the patient, often after 1 or 2 hours of sleep, and is usually relieved in the upright position.
