Outcomes in orthotopic heart transplantation following pacemaker implantation.
Do DH, Bailey KL, Beyer R, Neubuerger S, Bradfield J, Shivkumar K, Nsair A, Boyle NG. Do DH, et al. Among authors: boyle ng. Pacing Clin Electrophysiol. 2023 Jul;46(7):583-591. doi: 10.1111/pace.14716. Epub 2023 May 24. Pacing Clin Electrophysiol. 2023. PMID: 37221975
Prior studies have shown conflicting findings regarding the effect of PPM implantation on survival. We evaluated the effect of PPM indication on long-term re-transplant-free survival in OHT patients. METHODS: We conducted a retrospective cohort study of OHT patients at UCL …

PMID: 32558054 Free PMC article.
CONCLUSION: RFA for recurrent MMVT post-CSD is a reasonable treatment option with intermediate-term clinical success in 50% of patients. Clinical VT cycle length was significantly increased after CSD with associated improvement in mappable, hemodynamically tolerated VT dur …

Predict In-Hospital Code Blue Events using Monitor Alarms through Deep Learning Approach.
Xiao R, King J, Villaroman A, Do DH, Boyle NG, Hu X. Xiao R, et al. Among authors: boyle ng. Annu Int Conf IEEE Eng Med Biol Soc. 2018 Jul;2018:3717-3720. doi: 10.1109/EMBC.2018.8513269. Annu Int Conf IEEE Eng Med Biol Soc. 2018. PMID: 30441177
In the present pilot study, we hypothesize that sequential deep learning models, specifically long-short term memory (LSTM), could capture time-depend features in continuous alarm sequences preceding code blue events and these features may be predictive of these endpoints. …
