a? is pericardial knock S3 sound, don;t remember??

I change my answer should be earlyventricular filling so CCCC
05-31-2007, 05:23 PM
C .......and could be D too but i think time factor is more suggestive of C here

An early diastolic sound analogous to the normal third heart sound, but occurring somewhat earlier, due to rapid ventricular filling being abruptly halted by the restricting pericardium...

this pericardial Knock happens very soon after ventricle starts filling up as comapred with Normal Heart filling
