Afib treatment lightens up
Atrial fibrillation is an irregular, rapid heartbeat that interrupts normal blood flow and increases risk of stroke and clots. Normal heart rhythm can be restored by electroshock (electrical cardioversion), but implantable cardioverter defibrillators can cause pain and damage myocardial tissue.
Been There Done That – Cardioversion Sucks!
Rather than supply exogenous (he means Zapping Electrical shock) current, Nyns et al. combined atrial gene painting to deliver viral vectors encoding light-activatable ion channels with an implantable light source and rhythm detector, developing an autogenous arrhythmia termination system.
Enter the Automatic Afib Zapper!
This optogenetic approach restored normal heart rhythm in rat hearts ex vivo and in vivo under closed-chest conditions. Further testing in larger animal models is necessary, but results suggest that this could be a pain-free alternative to electroshock.
Did I Mention – Stop the Afib – Without electrical shock!
“The bioelectronic defibrillator can stop atrial fibrillation without an electrical shock. In this way, the heart can be reset in a fully automated manner and at any time.
We anticipate that this treatment for atrial fibrillation could improve both the patient’s quality of life and their prognosis.”
The researchers emphasise that considerable research is still needed before a treatment can be arrived at that is suitable for patients.
According to the researchers, however, it has now been demonstrated that the possibility exists.
