Does pericardiocentesis improve systolic time intervals in patients with cardiac tamponade?
Systolic time intervals are abnormal in cardiac tamponade and improve immediately following pericardiocentesis, suggesting utility in diagnosis and treatment monitoring.
May aid tamponade monitoring via systolic time intervals; leaves open validation in larger studies.
Systolic time intervals (STI) have been measured in three patients with cardiac tamponade. The left ventricular ejection time (LVET), the preejection period (PEP) and the ratio PEP/LVET deviated significantly from the normal values. All three parameters improved immediately after pericardiocentesis and aspiration. The total electromechanical systole changed to only a minor degree. Measurement of STI may be a valuable tool in the diagnosis and treatment of cardiac tamponade.

Brubakk et al. (1976) conducted a case report in Cardiac tamponade (n=3). Pericardiocentesis and aspiration vs. Pre-procedure (baseline) was evaluated on Systolic time intervals (LVET, PEP, and PEP/LVET ratio). Pericardiocentesis and aspiration immediately improved systolic time intervals (LVET, PEP, and PEP/LVET ratio) in three patients with cardiac tamponade.
