Using an automated external defibrillator (AED) can help restore the heart’s rhythm until emergency medical personnel arrive. Use an automated external defibrillator (AED) if available. Call for emergency medical assistance immediately. Begin CPR with chest compressions. Continue CPR until emergency responders take over.
Guideline-directed device therapy (GDDT) for long QT syndrome (LQTS) has evolved over the years and indications for an implantable cardioverter defibrillator (ICD) vary amongst professional cardiac societies.
Tetralogy of Fallot (TOF) represents the poster child for monomorphic ventricular tachycardia (MVT) in congenital heart disease. Sustained MVT affects approximately 10% of such patients at 30 years after cardiac repair and is inextricably related to the burden of sudden cardiac death (SCD).(1)
Classical example of polymorphic ventricular tachycardia is torsade de pointes associated with congenital or acquired QT interval prolongation. Recurrent ventricular tachycardia in spite of radiofrequency catheter ablation needs an implantable cardioverter defibrillator.
The subcutaneous implantable cardioverter-defibrillator (SICD) was developed with an aim to avoid lead-related complications associated with transvenous ICD (TV-ICD) systems. Patient selection and implant techniques have evolved greatly since that time.
This can be an especially trying time in the life of an adolescent with congenital heart disease, especially as they are undergoing the major transition of leaving the nest and going off to college, joining the workforce, or just moving far from home. This post was originally published in November 2017.
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. Therefore, I usually prefer temporary pacing which might be more controlled and is more predictable."
Congenital Heart Defects Some individuals are born with heart defects that cause parts of the heart to work harder, leading to enlargement over time. Implantable Cardioverter-Defibrillator (ICD) to help manage dangerous heart rhythms. Heart Transplant may be considered in severe cases where other treatments have failed.
He was resuscitated with chest compressions and defibrillation and 1 mg of epinephrine. On his bib it stated that he had a congenital heart disorder. This young male had ventricular fibrillation during a triathlon. He arrived in the emergency department hemodynamically stable. His initial ECG is shown here.
She was successfully revived after several rounds of ACLS including defibrillation and amiodarone. By EMS report, open pill bottles were found nearby at the scene, including quetiapine, fluoxetine, hydroxyzine, and gabapentin. On arrival to the ED the patient was intubated with normal vital signs.
This episode self terminated before defibrillation was possible. It is important to be aware that this does not rule out congenital long QT syndrome (LQTS). This run of TdP is initiated by a PVC — but it then self-terminates. ECG #3 Interpretation of ECG #3: This rhythm begins as Torsades de Pointes — that then becomes V-Fib.
Guidance for integrating risk markers with tools to estimate an individual patient’s SCD risk score is recommended to aid in the patient/clinician shared decision-making regarding implantable cardioverter defibrillator placement, incorporating a patient’s personal level of risk tolerance and specific treatment goals including quality of life.
Thrombus can sometimes occur when there is a central venous catheter or a multiple pacemaker or defibrillator leads there that can cause thrombus formation. So a prominent A wave in a complex congenital heart disease situation would indicate that interventricular septum is intact. Obstruction could be due to tumour or even a thrombus.
BackgroundSex‐specific risk management may improve outcomes in congenital long QT syndrome (LQTS). Anderson‐Gill modeling was performed for the end point of CE burden (total number of syncope, aborted cardiac arrest, and appropriate defibrillator shocks).
