The Veeraraghavan lab develops and applies light and electron microscopy approaches to understand how nanoscale structure affects the heart's rhythm in health and disease.
New #paper from the lab... Louisa Mezache out how #inflammation induced by a #viral #infection can disrupt #cardiac #nanostructure and promote #AFib.

Very cool study! I suspect we're only beginning to understand the importance of communication between myocytes and the vasculature. The more we understand the better we can intercept pathological remodeling processes.
Manning & Rivera et al. (www.jacc.org/doi/10.1016/...) show that pruning just a few capillaries in the SA node plunges the heart’s pacemaker into metabolic overdraft—slowing the rate and jacking up beat-to-beat variability. The physiological equivalent of running on fumes. @jaccjournals.bsky.social

no tiny wooden hut with a grass roof in the hills
but this city these people where I live still are impossible

mirror facing a mirror
nowhere else

on the deep green lily pad dew
has no color of its own

the mind is exactly this tree that grass without thought or feeling both disappear

Excited, not executed... Hopefully, that was obvious. This round goes to jet lag 🤦🏿‍♂️🤣🤦🏿‍♂️
Had the most wonderful time at @iiscbangalore at the *Collaborative Health Sciences Workshop* today! Razor sharp science in #cardiology, #neuroscience + filter coffee... Executed for the new collaborations. Thanks to Profs. Navakanta Bhat, @shivkumarmd for the invitation!

Congratulations to collaborator extraordinaire Prez Radwanski on the first publication of 2025: doi.org/10.1111/epi....
Delighted to have made some contributions to this work, where we uncover mechanisms underlying deadly proarrhythmic impacts of the #epilepsy #drug #lamotrigine.
Lamotrigine promotes reentrant ventricular tachycardia in murine hearts
Objective In 2021, the US Food and Drug Administration issued a safety warning concerning lamotrigine use in patients with underlying cardiac disorders. This warning was based on in vitro data that ...
