Throwback Thursday - Coratomic Pacemakers Coratomic, a PM manufacturer based in Indiana, PA, was 1 of 3 American companies producing atomic PMs in the 1970s (hence the name). The enthusiasm for plutonium PMs faded just as fast as it rose, in part due t…lnkd.in/gaieKEj4

What's Driving this AF? Patient s/p several AF ablation elsewhere presented with persistent AF > 1 year. Baseline bipolar map showed patchy low voltage areas with extreme fragmentation on the PW and anterior septum (green balls and red dots). After red…lnkd.in/gZ-GrPcg

Why some P waves are so Fragmented In AF patients, not infrequently we find very fragmented P waves in NSR. Here's a biatrial map in a patient s/p prior PVI, correlating intracardiac activation to 12L P waves. As we've been taught in school, the termina…lnkd.in/gzZxHYDZ

KYC in the RVOT/PA Area While focusing on our 3D maps during an ablation, it is easy to forget the important structures outside of the map. That's when ICE comes in handy. In this case of RVOT PVC, the successful site (blue dot) was at the level of pulm…lnkd.in/gXW7fJSV

Throwback Thursday - A Pacemaker for Man's Best Friend The caption of this 1987 press release photo reads: "Veterinarian John J. Martin of the Metairie Small Animal Hospital staff holds a sample pacemaker of the type he implanted in "Julep" a ten-year-o…lnkd.in/gRK3vwdh

Inflation or Deflation? A Physician’s perspective The consumer price index #CPI just hit a multi-generational high of 9.1%. The last time #inflation was this bad, I had hair down to my shoulder. When my hair was that long, #CMS used to pay $3,000 for…lnkd.in/g-ZCc-xA

Throwback Thursday - 2013 Ablation Here is an old case of roof flutter ablation from my younger days. How we actually accomplished anything for so many years without contact force, ablation index, or deflectable sheath still blows my mind. #epeeps #elec…lnkd.in/gguWcV57

@jeffrey_vinocur Good thought.

@JamesOngMD Fascinating. It took me a bit to get oriented on the ICE hopefully I am correct in my labeling below. I wonder if this may be SVC overriding a sinus venosus defect? On some views there seems to be dropout (curved arrow) and a few bubbles crossing (straight arrow).

Have you ever seen an SVC valve? The Eustachian valve is also known as the IVC valve. But have you ever seen an SVC valve? A search in the literature reveals what is termed "supernumerary valves." I find one case report lnkd.in/gPYwQqW9 Any inpu…lnkd.in/gCwNiQVw

Another SVC Tachycardia This pt with NICM s/p ICD has episodic elevated HR for years thought to be sinus tach. Eventually AF ensued and pt came for PVI. In addition to AF, an AT was mapped to the ridge between SVC and RA. Note on ICE the thickness of t…lnkd.in/gYrt7_6F

@ugurkucuk Yes great history. Crazy to realize that all these innovation happened during our lifetime.

@JamesOngMD I see Wilson Greatbatch's book on your desk. Now I am reading a signed copy. Amazing book for whose interested in history of EP.
