The purpose of this work was to study the effect of nitroglycerin (glyceryl trinitrate) to ballistocardiographic signal (BCG) recorded in sitting position by using Electromechanical Film (EMFi) sensors. ECG, BCG, ankle pulse signal and carotid pulse (CP) signal from the neck near the carotid artery were recorded from a single person and duration of the signal components according to R wave of the ECG and amplitudes of the signals were studied. In the first study the effect of 1 nitroglycerin pill was studied and in the second study the effect of exercise and the intake of 2 nitroglycerin pills were examined. The time domain properties of BCG, CP and ankle pulse signals stayed somewhat stable due to nitroglycerin intake. Noticeable increase was seen in some systolic signal amplitudes. Diastolic signal amplitudes mainly decreased. Signal traces became smoother and the fluctuation of the ballistic signals decreased. Nitroglycerin intake had a major but temporary effect on the heart-vasculature system due to increased aortic elasticity.
