Visual Evidence of Ischemic Preconditioning During PCI Using 80 Lead ECG Body Surface Mapping

Ischemic preconditioning (IPC) is a well-documented phenomenon. Short episodes of sublethal ischemia provide cardioprotective effects for subsequent longer duration ischemic events. Although the exact mechanism of IPC is not yet known, the chemical basis of IPC seems to involve preservation of ATP or collateral vascularization recruitment. In this case report, we present visual evidence of ischemic preconditioning using Heartscape Technologies 80 Lead ECG device. The 80 Lead ECG is described as a body surface mapping modality, converting its inputted 80 lead ECG data into a 3-Dimensional color coded map. The 80 lead ECG device can detect instantaneous ischemic changes. Different studies have been performed to show different clinical and biochemical aspects of IPC. However data regarding direct visual evidence of this phenomenon is lacking. The secondary objective of this study is to show the ability of 80 lead ECG to identify ST-segment elevation and depression during ischemic events. The utility of 80 Lead ECG body surface mapping is enormous when evaluating ischemic events.
