Abstract
BACKGROUND: We report the first in-literature animal experiment to validate the intracoronary ECG signal acquired from a coronary wire compared with the direct signal from an epicardial electrode. METHODS: An animal model study was performed in a 40 kg pig. Acute myocardial ischemia was induced by intracoronary balloon inflation for 60 s. Simultaneous ECG recording and PCI guidewire electrical and motion measurements were obtained. RESULTS: The first ischemic manifestation was myocardial kinetic disturbances, followed by ST-elevation. The signals recorded from the PCI guidewire and the epicardial electrode ran simultaneously, from the induction of ischemia to complete recovery of signal. CONCLUSION: The intracoronary ECG signal acquired from a coronary wire was equivalent to the direct signal received from an epicardial electrode. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT04061525.
