Overview
There are no x-ray findings associated with catecholaminergic polymorphic ventricular tachycardia.
Implantable Cardioverter-Defibrillator
- ICD should be used with pharmacologic therapy.[1]
- Indications:[2]
- Patients who are at high risk of cardiac arrest
- Patients who have survived a sudden cardiac arrest
- Patients who have experienced syncope or sustained VT despite optimal medical therapy and left cardiac sympathetic denervation. [].
- Implantable cardioverter-defibrillator may have harmful pro-arrhythmic effects in some patients, since painful shocks can increase catecholamine release and trigger further arrhythmias and triggering VT storm, leading to a malignant cycle of shocks that may even culminate in death.
- To reduce the risk of inappropriate shocks, it is important to program ICD with long delays before shock delivery and high cut-off rates for heart rate recognition; and always administer beta blockers concurrently.[3]
