Change in P wave terminal force and systolic time intervals during exercise in patients with coronary artery disease. 1978

O Brubakk, and G A Rossland, and O M Pedersen

P wave terminal force (Ptf) and systolic time intervals (STI) were determined non-invasively from electrocardiogram, phonocardiogram and carotid pulse wave in fifteen men with coronary artery disease, before and during exercise. Left ventricular end diastolic pressure (LVEDP) and stroke volume (SV) were determined at catheterization simultaneously with the non-invasive recordings. Pre-ejection period (PEP) shortened in eleven patients, left ventricular ejection time (LVET) shortened in eight and Ptf and PEP/LVET decreased in ten patients during exercise. Ptf was significantly correlated to LVEDP both at rest (r = -0.66) and during exercise (r = -0.79). The change in Ptf and LVEDP was less correlated (r = -0.52). The change in LVET (r = -0.50), the change in PEP (r = 0.62) and in the index PEP/LVET (r = 0.65) was correlated to the change in SV. The use of both Ptf and STI may be of value in estimating left ventricular function during exercise in patients with coronary artery disease.

D010701 Phonocardiography Graphic registration of the heart sounds picked up as vibrations and transformed by a piezoelectric crystal microphone into a varying electrical output according to the stresses imposed by the sound waves. The electrical output is amplified by a stethograph amplifier and recorded by a device incorporated into the electrocardiograph or by a multichannel recording machine. Phonocardiographies
D011674 Pulse The rhythmical expansion and contraction of an ARTERY produced by waves of pressure caused by the ejection of BLOOD from the left ventricle of the HEART as it contracts. Pulses
D002339 Carotid Arteries Either of the two principal arteries on both sides of the neck that supply blood to the head and neck; each divides into two branches, the internal carotid artery and the external carotid artery. Arteries, Carotid,Artery, Carotid,Carotid Artery
D003327 Coronary Disease An imbalance between myocardial functional requirements and the capacity of the CORONARY VESSELS to supply sufficient blood flow. It is a form of MYOCARDIAL ISCHEMIA (insufficient blood supply to the heart muscle) caused by a decreased capacity of the coronary vessels.
