Implication

ACGu identifies shortest EMI; hypothesis-generating for electromechanical timing, requiring prospective validation before clinical use.

Structured PICO

Population

50 normal subjects

Intervention

Measurement of left ventricular electromechanical interval (EMI) using apex upstroke (ACGu) and mitral component of the first heart sound (IM)

Comparator

Kinetocardiographic endpoint ('Initial Ventricular Movement')

Outcome

Left ventricular electromechanical interval (EMI)surrogate

The apex upstroke (ACGu) provides the shortest and most logical electromechanical interval (22 ± 9.8 msec) as it represents the earliest clinically detectable mechanical activity.
