[Mechanocardiography as a screening method in chronic ischemic heart disease]

On 121 patients with ischaemic heart disease mechanocardiographic examinations were carried out on conditions of rest and partly under conditions of ergometric load and were compared with a group of healthy persons. It was shown that in the patients with ischaemic heart disease there appeared a significant shortening of the ejection time (LVETk), prolongation of the frequency-corrected preejection time (PEPk) as well as of the isovolometric contraction time (ICT and ICTk), an enlargement of the quotient (see article) and reduction of (see article) in rest. Under load the differences between healthy persons and patients with ischaemic heart disease became more clearly with regard to the quotients (see article) as well as (see article) and proved as favourable for the judgment of the cardiomechanics. With the help of the above mentioned mechanocardiographic parameters in connection with the usual diagnostic methods according to our opinion patients with ischaemic heart disease may be diagnosed for the greatest part.
