Transient S-T elevation detected by 24-hour ECG monitoring during normal daily activity

Seven out of 174 patients subjected to continuous 24-hour ECG monitoring because of atypical chest pain and/or palpitations were found to have transient S-T elevation. Two were diagnosed as suffering from neurocirculatory asthenia, three had myocardial infarction, and two suffered, most probably, from Prinzmetal's variant angina pectoris. We believe that the finding of transient S-T elevation is of special significance, because of the pathological and therapeutic implications, and that continuous ECG monitoring during unrestricted daily activities provides a unique opportunity to detect this condition more frequently.
