See this post: How a pause can cause cardiac arrest 2. It should be kept in mind that on occasions, beta-one agonist can result in increased ventricular ectopy e.g., in severe myocardial ischemia (by increasing myocardial demand), or sometimes with congenital long-QT syndrome. The plan: 1. Place temporary pacemaker 3.

Abstract Introduction Long QT syndrome (LQTS) is a cardiac channelopathy characterized by QT prolongation and a potential for arrhythmic syncope, sudden cardiac arrest or deaths (SCA/SCD). It has been speculated that patients with LQTS might have a primary sinoatrial node (SAN) phenotype of chronotropic insufficiency (CI).

Patients were classified by CVD type: adult congenital heart disease, cardiac arrest, connective tissue disease with aortopathy, ischaemic cardiomyopathy, non-ischaemic cardiomyopathy or valve disease. We examined demographic, anaesthetic and procedure-related variables and in-hospital maternal and fetal outcomes.

However, according to these diagnostic criteria (JACC 2011; 57(7):802), it is a Bazett corrected QT of less than 330-370, depending on other diagnostic criteria, including 1) h/o cardiac arrest, 2) sudden syncope, 3) family hx of sudden unexplained arrest at age less than 40, 4) family hx of SQTS. Some other points: 1.
