Implication

Enables noninvasive quantification of stress-induced systolic-diastolic mismatch; leaves open its prognostic value in stress echocardiography.

Structured PICO

Does an operator-independent cutaneous force sensor accurately monitor diastolic and systolic times during stress echocardiography in patients referred for stress testing?

Population

161 consecutive patients (106 males, mean age 62 ± 13 years) referred for stress echocardiography (115 for exercise, 40 for dipyridamole, 6 for pacing stress).

Intervention

Operator-independent, force sensor-based, diastolic and systolic time recording during stress using a cutaneous linear accelerometer based on first and second heart sound amplitude vibrations.

Outcome

Proportion of the cardiac cycle occupied by systole and diastole (absolute values, msec)surrogate

A cutaneous force sensor can feasibly monitor cardiological systolic and diastolic duration during stress echocardiography, allowing for the quantification of stress-induced systolic-diastolic mismatch.
