Pulses paradoxes is characterized by
During inspiratation there is a fall in intrathoracic pressure, this increases the venous return to the right heart. Consequently, the interventricular septum bulges to the left side thus reducing is a left ventricular volume. This leads to reduced stroke volume and reduced systemic pressure.
Pulses paradoxes actually exaggerated physiologic decrease in systemic blood pressure during inspiration.
The paradox of pulses paradoxes, is audible heart sounds without a radial pulse.
Causes of Pulses Paradoxes are;
|Cardiac Causes||Extracardiac pulmonary causes||Extracardiac non-pulmonary causes|
|Cardiac tamponade||Bronchial asthma||shock|
|Pericardial effusion||Tension pneumothorax||Volvulus of the stomach|
|Constrictive pericarditis||Diaphragmatic hernia|
|Restrictive cardiomyopathy||Superior vena cava obstruction|
|Pulmonary embolism||Extreme obesity|
|Acute myocardial infarction|
