Preferred patterns of diastolic timed vibrations for pre-hospitalization treatment of acute coronary ischemia

This paper presents and evaluates preferred patterns of vibrations and active breaking techniques for the Diastolic Timed Vibrator (DTV). DTV uses low frequency mechanical vibrations applied to the chest to help in clot dissolution in pre-hospitalization treatment of acute coronary ischemia. In this work, we argue that random and ramp type vibration patterns increase the performance of the DTV method. Furthermore, we present results for various methods of vibration stopping aiming at reduction of vibration overspill into the systole of heart cycle of the patient.
