Gradient-weighted Class Activation Mapping (Grad-CAM) was applied to the VGG16 Two modalities of data were input to the model: polarmap imagesįrom SPECT MPI and tabular data from clinical features and ECG parameters. Model was constructed by combining a pre-trained VGG16 module and a multilayer Left ventricular ejection fraction (LVEF) > 5% at a 6-month follow up. CRT response was defined as an increase in 218 patients who underwent rest gated SPECT The purpose of this study is to combine clinical variables,įeatures from electrocardiogram (ECG), and parameters from assessment ofĬardiac function with polarmaps from gated SPECT MPI through deep learning (DL) Predicting cardiac resynchronization therapy (CRT) patient outcomes, but still

Down climbed on all fours back through the 1:00 chute and made it back to the lodge via skis from the top of Palmer lift down, 3 hours and 6 minutes on the descent, with skis for the last 2800 vertical feet.īreathtaking peak, great climb. There were some teams having difficulty navigating the berchsend, and thus having trouble with the pearly gates, so that guided our decision to follow the old route.įrom my observation, the berchsend opened about foot and a half, but my vantage point was from a distance. I took us 7 hours and 6 minutes to ascend, including multiple stops. It was sunny, clear and virtually windless on the summit. We then made our way to the Hogsback and proceeded to climb by the hot rocks and ascend the 1:00 chute. Ditched our skis and traded them for crampons. We skin skied from the parking lot at timberline lodge to where the Cat drops off the other climbers. Despite a virtual white-out only 5 hours earlier, we encountered cold and clear weather (as forecast on this website). At 1:00 am Friday May 20, 2016, we ascended the south side route via the old chute.
