inspiration, which causes an increase in blood flow to the right chambers,

increasing their volume, secondarily causes a displacement of the

normal heart this exaggerated displacement, caused by the pressure exerted

systolic collapse of the venous pulse, i.e., the pressure drop due to atrial

relaxation (also partly due to a downward displacement of the RV base during

systole). Sinus Y represents the diastolic collapse of the venous pulse,

| 29 |
-
i.e., the pressure drop that occurs from the moment blood enters the

-
tricuspid valve into the ventricle. In cardiac tamponade, the deep sinus X

is characteristic. In constrictive pericarditis, the deep Y sinus. For all

these reasons, the correct answer is 5.

- text: A patient with a history of febrile illness and chest pain comes to the hospital with dyspnea and tachypnea. On physical examination his blood pressure is low, jugular venous pressure is elevated with a deep descending sinus "X" and he has a paradoxical pulse. What pathology should you suspect?
