Cardiac Arrhythmias During Anesthesia
Brugada & anesthesia: The risk of a drug causing or worsening a cardiac rhythm disturbance is a concern with some anesthetic drugs. For patients w/ Brugada syndrome, this is a much more significant issue. In a study of 57 patients w Brugada, a single dose of propafol did not cause problems, but extreme caution is advised for general anesthesia of Brugada patients especially w prolonged propafol infusion. ...Read moreSee 2 more doctor answers
Can Intravenous Zofran for nausea/vomiting cause Cardiac arrest or ventricular arrhythmia? Is it safe for heart patients with ven. arrhythmia?
Intermittent cardiac arrhythmia found during carotid cta 3 yrs ago. Experiencing seizures w/heart rate spikes could arrhythmia contribute to this?
Needs rapid evaluation: Although chronic hypertension is among the most common causes of nonischemic cardiomyopathy, there appears to be no hypertensive history in this case. With an ejection fraction of 20%, sudden life-threatening arrhythmia is a significant risk. An implantable defibrillator must be considered urgently. A Zoll Vest could be considered if there is any delay in implanting a defibrillator. In addition, consideration should be given to a myocardial biopsy to search for an infiltrative cardiomyopathy. Diuretic, beta blocker and vasodilator therapy might be limited by a low blood pressure. If there is a wide QRS, resynchronization with a biventricular pacemaker might help restore ventricular function. The prognosis (and treatment) will be dependent upon the underlying cause of the cardiomyopathy. ...Read moreSee 9 more doctor answers
After cardiac resuscitation during surgery, is it viable/possible to resume anesthetics? (Propofol/Remifentanil)
No: In the absence of any other evidence of heart disease, particularly coronary or ischemic heart disease, ventricular bigeminy is a benign rhythm that usually causes neither symptoms nor problems, and often comes and goes. There is generally no reason to treat it. If your doctor has concern, a holter monitor can be applied for 24 hours to see if there are any truly worrisome arrhythmias. ...Read more
Can an electrocardiogram prevent sudden cardiac arrest in young teenagers/adults who die during marathons?
Screen test: ECG is used because it is relatively inexpensive. We have no good cost effective screening test. Cardiac arrest is rare when compared to the numbers of exercising population. Tests become more effective when a specific question within the effectiveness of the test are the reason for the test. ...Read moreSee 5 more doctor answers
Is there the same risk of post-operative death (e.G., cardiac arrhythmia) from conscious sedation as there is with general anesthesia?
Yes : Yes but only when the tachycardia is fast and not tolerated . But the electric current has to be synchronized with the heart beat.This is most appropriately called cardioversion than defibrillation the latter being unsynchronized electric shock for ventricular fibrillation which is a chaotic ineffective rhythm. ...Read more
