Chronic invasive remapping provides a close look at pulmonary vein isolation durability and raises an important question: could seeing tissue contact become the next major advance in PFA workflow? \nTwo additional studies examine practical PFA safety signals. One evaluates hemolysis-associated acute kidney injury, pulse count, chronic kidney disease, extensive left atrial ablation, and whether protocol-based hydration can reduce renal risk. Another quantifies acute blood pressure drops during circular-array PFA and identifies the first pulmonary vein treatment as the period of greatest hemodynamic vulnerability. \nThe pacing and ventricular arrhythmia section includes:\n The randomized PACE-HF trial, comparing left bundle branch area pacing with conventional right ventricular pacing \n A preclinical comparison of left bundle branch area antitachycardia pacing and right ventricular ATP \n Pulsed ultrahigh-frequency spinal cord stimulation as a potential neuromodulation strategy after myocardial infarction \nWe then move beyond the EP laboratory to examine:\n Insomnia and incident atrial fibrillation \n The lifetime cardiovascular tradeoff between high cardiorespiratory fitness and AF risk \n Whether the balance of moderate and vigorous physical activity influences cardiovascular and overall mortality \nEach paper is examined through its rationale, methodology, statistical meaning, limitations, and potential clinical consequences.\nCan direct tissue visualization improve PFA durability? Should PFA pulse count be treated as a biologic dose? Is right ventricular pacing...","thumbnail_url":"https://img.transistorcdn.com/C7iPWVsHlGRm13syn3X4eXGLcqOXyzcuH5XmVutqgHc/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS9jMzFi/ZTYxOTI1M2U4NGRj/OGZmZjBhMDFlMjFm/NDQwMC5wbmc.webp","thumbnail_width":300,"thumbnail_height":300}
