What is the McConnell logo?
Right heart strain is a medical finding of right ventricular dysfunction, in which the heart muscle of the right ventricle is deformed. Right heart strain can be caused by pulmonary hypertension, pulmonary embolism, right ventricular infarction, chronic lung disease, pulmonary stenosis, bronchospasm, and pneumothorax.
What is the 60 60 symbol?
The 60/60 sign on echocardiography refers to Shortened right ventricular outflow tract acceleration time (AT <60 ms) coexisted with pulmonary artery systolic blood pressure (PASP) less than 60 mmHg (but more than 30 mmHg).
What Caused McConnell’s Signs?
McConnell logo depicts a regional pattern Transthoracic echocardiography showing acute right ventricular dysfunction First observed in a cohort of patients with acute pulmonary thromboembolism.
What is S1Q3T3?
Discussion: The McGinn-White sign or, commonly referred to as the S1Q3T3 pattern, is Nonspecific Findings Associated with Right Heart Strain1. A common misconception is that this marker is only associated with pulmonary embolism, which is only one possible cause of right heart strain.
What is McConnell’s logo on the Echo?
McConnell’s logo is Distinct echocardiographic features of acute massive pulmonary embolism. It is defined as a regional pattern of right ventricular dysfunction with intermediate free wall akinesia and apical wall hypercontraction.

Can you see PE on the echo?
diagnosis. Several two-dimensional echocardiographic criteria for pulmonary embolism have been published.In significant pulmonary embolism (angiographic Miller index > 30%), echocardiography can detect Right ventricular dilatation, right ventricular hypokinesis/dysfunction, or pulmonary hypertension (1,2).
What is a Hamptons Hump?
Hampton’s hump is A radiological landmark consisting of a peripheral wedge-shaped opacity adjacent to the pleural surface, representing a pulmonary infarction distal to a pulmonary embolism. 1. Due to the good pulmonary perfusion of collateral vessels, it is rare in clinical practice.
How common is S1Q3T3?
The reported incidence of S1Q3T3 is Between 12% and 50% in acute pulmonary embolism and is nonspecific.
How sensitive is the S1Q3T3?
The classic S1Q3T3 pattern is described as occurring in only 20% of cases, and Ferrari et al. (3) found that this pattern has Sensitivity was 54%, specificity was 62%Other ECG findings in PE include right bundle branch block, right axis deviation, atrial fibrillation, and T wave changes (2,3).
How accurate is the S1Q3T3?
S1Q3T3 and other ECG results become useful when applied together rather than individually – eg, in the Daniel scale: the highest score is 21. associated with the severity of pulmonary hypertension. > or = 10 fractions: Specificity was 97.7% and sensitivity was 23.5%
How do you identify the right heart strain?
Features described include:
- Abnormal position of the ventricular septum 1 Flattening of the ventricular septum. …
- Right ventricle enlargement (the right ventricle is larger than the left ventricle)
- Enlarged lung trunk (larger than the aorta)
- Features of right heart failure. Inferior Vena Cava Contrast Reflux 1
Why does PE cause right heart strain?
sports performance Height of afterload in RVand the subsequent increase in RV wall tension, may lead to dilation, dysfunction, resulting in decreased right coronary flow and increased RV myocardial oxygen demand.
What is the S1Q3T3 ECG pattern?
However, « S1Q3T3 » mode acute cor pulmonale It’s classic; it’s called the McGinn-White logo. 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 is lung acceleration time?
The pulmonary artery acceleration time (PAAT) is A Quantitative Method for Studying Blood Velocity Characteristics of Right Ventricular Outflow Tract (RVOT) in response to changes in ventricular mechanical properties and pulmonary vascular load and compliance.
What are Q waves?
AQ waves are Any negative deflection before the R wave. The Q wave represents the normal depolarization of the interventricular septum from left to right. Small « interval » Q waves are usually seen in the left leads (I, aVL, V5, and V6)
How do they check for pulmonary embolism?
When this condition is suspected, some important tests may be performed, including:
- Pulse oximeter. Usually, the first test done when PE is suspected is the blood oxygen level. …
- Arterial blood gas. …
- Chest X-ray. …
- Ventilation-Perfusion Scan (VQ Scan) …
- Helical computed tomography of the chest. …
- Pulmonary angiography. …
- Echocardiography.
What is cor pulmonale?
Cor pulmonale is Diseases that cause right side of the heart to fail. Long-term hypertension in the pulmonary arteries and the right ventricle of the heart can lead to cor pulmonale.
Why does pulmonary embolism occur?
pulmonary embolism When a blood vessel in your lung is blocked. Most of the time, this blockage is caused by a blood clot and occurs suddenly. Usually, a pulmonary embolism is caused by a blood clot traveling up a deep vein in your body, usually your leg.
Can a chest X-ray detect PE?
chest x-ray
Although X-rays do not diagnose pulmonary embolism When pulmonary embolisms are present, they may even appear normal, and they rule out conditions that mimic the disease.
What is S1 on an ECG?
The first heart sound (S1) represents Atrioventricular (mitral and tricuspid) valve closure Because ventricular pressure exceeds atrial pressure at the onset of systole (point a). S1 is usually a single sound because mitral and tricuspid valve closures occur almost simultaneously.
What is a Klee Line?
Spacer lines, also known as Kerley lines, are Visible when interlobular septa in the lung interstitium become prominent. This may be due to lymphatic congestion or edema of the interlobular septal connective tissue. They usually occur when pulmonary capillary wedge pressure reaches 20-25 mmHg.
What does a Kerley B line look like?
They are short, thin lines running through the lungs, Has a mesh appearance. They may represent thickening of the anastomotic lymphatic vessels or superposition of many Kerley B lines.
How does a VQ scan work?
A lung VQ scan is an imaging test that uses a ventilation (V) scan to measure airflow and airflow in your lungs Perfusion (Q) scan to see where blood is flowing in the lungs. It uses a special X-ray scanner outside your body to create a picture of the air and blood flow patterns in your lungs.
What is a cus echo?
echocardiography Show us the structure and function of the heart. It provides information about the pumping function of the heart and the size of the heart. It shows us information about heart valves and other heart structures. An echocardiogram also shows blood flow patterns through the heart.
