Tiivistelmä

In this paper, we attempt to classify the pre- and postoperation cardiac conditions of ST-elevation myocardial
infarction (STEMI) utilizing seismocardiography (SCG)
and gyrocardiography (GCG) signals recorded solely by a
smartphone. SCG and GCG signals were recorded from 20
MI patients who were admitted to Emergency Department
of Turku Hospital. Two measurements were recorded from
each subject, one before they proceeded to percutaneous
coronary intervention (pre-operation) and one afterwards
(post-operation) with an average time interval of 2 days.
Noise and artefact removal were applied to the signals and
subsequently 25 features were extracted. Two classification algorithms, random forest (RF) and support vector
machines (SVM), were deployed to discriminate the two
cardiac conditions. Accuracy rates of 74% and 78% were
obtained for RF and SVM, respectively. The results indicate that smartphone SCG-GCG based ischaemia analysis
has clinical implications that warrants further investigations.
