Hamman's sign (rarely, Hammond's sign [1] or Hammond's crunch [2]) is a medical sign consisting of a crunching, rasping sound, synchronous with the heartbeat, [3] heard over the precordium in spontaneous mediastinal emphysema.
Pulsus alternans is diagnosed by first palpating the radial or femoral arteries, feeling for a regular rhythm but alternating strong and weak pulses. Next, a blood pressure cuff is used to confirm the finding: the cuff is elevated past systolic pressure and then slowly lowered cuff towards the systolic level.
Chest x-ray demonstrating severe atelectasis or collapse of the right lung and mediastinal shift towards the right. Atelectasis is the partial collapse of a lung that is reversible. There are numerous etiologies, including post-operative atelectasis, surfactant deficiency, mucus plugging, and foreign body aspiration.
Apical four chamber ultrasound view of heart. Transthoracic echocardiography (TTE) uses ultrasonic waves for continuous heart chamber and blood movement visualization. It is the most commonly used imaging tool for diagnosing heart problems, as it allows non-invasive visualization of the heart and the blood flow through the heart, using a technique known as Doppler.
Water Bottle Heart is a descriptive term used in radiology to describe the appearance of the cardiac silhouette on a chest X-ray when it resembles the shape of a water bottle. This sign is associated with pericardial effusion , a medical condition characterized by the accumulation of fluid in the pericardial cavity surrounding the heart.
AP chest x-rays are harder to read than PA x-rays and are therefore generally reserved for situations where it is difficult for the patient to get an ordinary chest x-ray, such as when the patient is bedridden. In this situation, mobile X-ray equipment is used to obtain a lying down chest x-ray (known as a "supine film").
X-ray examination of the chest may show increased heart size (mimicking other possible causes of enlargement). [24] Cardiac MRI - In athlete's heart, there is balanced atrioventricular remodeling, reduced thickening of the heart after detraining, no late gadolinium enhancement, low to normal T1 signal, and normal extracellular volume. [25]
A large cardiac tamponade will show as an enlarged globular-shaped heart on chest x-ray. During inspiration, the negative pressure in the thoracic cavity will cause increased pressure into the right ventricle. This increased pressure in the right ventricle will cause the interventricular septum to bulge towards the left ventricle, leading to ...
