Systolic timings - EKG, Pressure Traces...

Relationship of electrical to mechanical events.
1 - Electromechanical systole
2 - LV Ejection time (LVET)
3 - Pre-ejection period (PEP)
Note: Dicrotic notch in aortic pressure wave corresponds to aortic valve closure. Portion of arterial waveform after dicrotic notch represents peripheral vascular recoil and reflection wave.
