i guess u wanna know differences b/w pericardial effusion and constictive pericarditis. usually we have to differrentiate b/w constricitive percarditis amd cardiac temponade. please eloborate what u want.

Sorry- I meant how do you differentiate between constrictive pericarditis and cardiac tamponade?

ECG changes... in Pericarditis ST elevation through out all leads. Tamponade not. Pain and fever in preicarditis, not in tamponade. Dynamics of both can be simmilar, but tamponade more acutely develops, while in pericarditis there may be a Hx of inflatory process somewhere for several days before the event.

also electrical alternans and low voltages across the board in a tamponade but not in a constrictive pericarditis

if i remember correctly there is pulsus paradoxus in contrictive pericarditis and kussmual sign in cardiac temponade. i f i m wrong plz correct me

palsus paradoxus is definetely present in tamponade... Now describe that "pulsus" ..what do you see in that sign?

and describe Kussmaul's sign as well while we at it :-) it would be easier for others to understand why those are present in each condition.

Kussmaul by the way will be seen in both.

i think i wrote it exactly opposite. mbwannabe, it was given in q bank that kussumual is present in temponade and palsus paradoxus in constrictive pericarditis (i hope i got it rite this time!)

I don't know what the q-bank says...honestly...But here is a definition...it is seen in constrictive pericarditis. It is a paradoxical increase in venous distention and pressure during inspiration; seen occasionally in effusive-constrictive pericarditis when tamponading pericardial fluid overlies a constricting epicarditis.
My be I read it wrong?

Another striking abnormality of constrictive pericarditis is the failure of intrathoracic pressure changes during respiration to be transmited to the pericardium and intracardiac chambers. As a consequence, during inspiration, systemic venous and right arterial pressures do not fall and venous flow into the right ventricle does not increase, in contrast to the situation in normal subjects and patients with cardiac tamponade. In some patients, systemic venous pressure may actually increase with inspiration, i.e., Kussmauls’s sign. This finding may occur in other disorders such as chronic right ventricular failure and restrictive cardiomyopathy. However, it does not occur in acute cardiac tamponade, in which the inspiratory fall in intrathoracic pressure to the fluid-filled pericardial space. Pulsus paradoxus ( the inspiratory fall of aortic systolic pressure greater than 10 mm Hg ) is also less common in constrictive pericarditis than in cardiac tamponade, in which the exagerated increase in right ventricular filling during inspiration at the expense of left ventricular filling is more prominent
:shock: this is too much of info :wink:
