ST Changes Observed in Short Spaced Bipolar Leads Suitable for Patch Based Monitoring

  • This article investigates the selection of optimal ECG leads for the detection of ST changes more likely to appear in patch systems with closely spaced leads. Method: We analysed body surface potential maps (BSPMs) from 44 subjects undergoing PTCA. BSPMs were recorded at 120 sites and these were expanded to 352 nodes (Dalhousie torso) using Laplacian interpolation. A total of 88 BSPMs were investigated. This included the 44 subjects at baseline and the 44 subjects at peak balloon inflation (PBI). At PBI the subjects had various coronary arteries occluded (14 LAD, 15 LCX, 15 RCA). All possible bipolar leads were calculated for each subject. Leads were ranked based on the maximum ST-segment change between baseline and PBI for each subject. Leads with electrode spacing of more than 100 mm were excluded. The highest ranked lead was chosen as the short spaced lead (SSL) on the anterior torso. Result: The median ST-segment change for the chosen SSL for each vessel was LAD = 134 µV, LCX = 65 µV, RCA = 166 µV.

The maximum ST segment change observed for the same lead was LAD = 277 µV, LCX = 166 µV, RCA = 257 µV . For comparison, the highest median observed on the 12-lead ECG for each vessel was LAD = 137 µV (V3), LCX = 130 µV (III), RCA = 196 µV (III).show moreshow less
