CIED implantation in patients with arrhythmia, cardiomyopathy, and syncope were examined. Subcategories (complete heart block, atrial fibrillation\/atrial flutter, ventricular tachycardia\/ventricular fibrillation\/cardiac arrest, sick sinus syndrome, and ischemic and nonischemic cardiomyopathy) were investigated. Primary outcome was implantation of CIEDs in men versus women adjusted for age and comorbidities. Secondary outcomes were trends over time, time to implant, length of stay, emergency status, and 30\u2010day survival. Of 1\u2009291\u2009258 patients with cardiovascular admissions, 287\u2009563 had arrhythmia, cardiomyopathy, or syncope and 29\u2009080 (2.3%) received a CIED (22\u2009472 pacemakers, 6808 defibrillators, 3207 resynchronization therapy). Women with arrhythmia, cardiomyopathy, or syncope were less likely to have pacemakers (adjusted odds ratio [aOR], 0.78 [95% CI, 0.76\u20130.80]), defibrillators (aOR, 0.4, [95% CI, 0.40\u20130.45]) and resynchronization therapy (aOR, 0.66 [95% CI, 0.61\u20130.71]). Differences persisted across subcategories, including fewer pacemakers in complete heart block (aOR, 0.89 [95% CI, 0.80\u20130.98]) and syncope (aOR, 0.70 [95% CI, 0.63\u20130.79]); fewer defibrillators in ventricular tachycardia\/ventricular fibrillation\/cardiac arrest (aOR, 0.69 [95% CI, 0.61\u20130.77]); and less resynchronization therapy in cardiomyopathy (aOR, 0.62 [95% CI, 0.51\u20130.75]). Men and women receiving devices had higher 30\u2010day survival compared with those who did not receive a device, and 30\u2010day survival was similar between men and women receiving devices.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p xml:lang=\"en\">Lower CIED implantation was seen in women versus men, across nearly all indications, including complete heart block and ventricular tachycardia\/ventricular fibrillation\/cardiac arrest. The underuse of cardiac devices among women may arguably reflect a sex bias and requires further research.<\/jats:p>\n
