Discontinue all negative chronotropic agents, since the risk of torsade is much higher with bradycardia or pauses. Because she has cardiomyopathy and ventricular dysrhythmias, the pacer included an Implanted Cardioverter-Defibrillator (ICD) Echo 6 days later after CRT: Normal estimated left ventricular ejection fraction. The plan: 1.

There is also bradycardia. Bradycardia puts patients at risk for "pause-dependent" Torsades de Pointes. Torsades in acquired long QT is much more likely in bradycardia because the QT interval following a long pause is longer still. Could the dysrhythmias have been prevented?

Opinions vary widely on the K level at which a patient must be admitted on a monitor because of the risk of ventricular dysrhythmias. My rationale is that if the K is affecting the ECG, then it is affecting the electrical milieu and can result in serious dysrhythmias. Until some real data is available, my opinion is this: 1.

PVCs N ot generally considered abnormal ECG findings: Isolated PAC, First Degree AV Block, Sinus bradycardia at a rate of 35-45, and Nonspecific ST-T abnormalities (even if different from a previous ECG). Thus, if there is documented sinus bradycardia, and no suspicion of high grade AV block, at the time of the syncope, this is very useful.
