Why is an electrical shock delivered to correct abnormal heart rhythm?

Why is an electrical shock delivered to correct abnormal heart rhythm?

Highly effective: It "sets the clock back to zero" so to speak. It synchronizes all the electrically conducting cells in the heart to begin their cycle at the same instant. It interrupts and stops abnormal rhythms. It doesn't hurt and there are generally no side effects so in that regard, it's better than medicines. The downside is that one must be put to sleep, albeit briefly, for it. ...Read more

What is an electrical shock delivered to the heart to correct abnormal heart rhythms called?

Cardioversion-defib: An implantable aicd has cardioversion and defibrillation capabilities. However, usually, it delivers a defibrillatory shock when it detects a dangerous rhythm. Of course, the energy is much lower since less tissue needs to be penetrated (the electrical lead goes directly into the heart). ...Read more

When is ?Digitalis? Used to cure abnormal heart rhythms?

When is ?Digitalis? Used to cure abnormal heart rhythms?

Never: Digitalis is used to control the ventricular rates of some abnormal fast atrial arrhythmias or svt. In atrial fibrillation it is utilized to control the fast rate. It does not "cure" the problem nor does it actually prevent the atrial arrhythmias, as antiarrhythmic medications would. ...Read more

Which anti-arrhythmic medication is best to control frequent, non-sustained, monomorphic ventricular arrhythmias with a structurally NORMAL heart ?

Which anti-arrhythmic medication is best to control frequent, non-sustained, monomorphic ventricular arrhythmias with a structurally NORMAL heart ?

May need nothing: Unless causing symptoms or a cardiologist finds some.underlying abnormality what you describe does not need treatment. Caffeine, lack of sleep, stress, alcohol and decongestants like pseudofed, and energy drinks will all exacerbate the problem. If it needs treatment a beta blocker like Metoprolol or Coreg (carvedilol) are good choices Too much thyroid medication can bring this out as well. ...Read more

What is an abnormal heart rate that can impair cardiac output called?

What is an abnormal heart rate that can impair cardiac output called?

Cardiac Output: Cardiac output equals stroke volume x heart rate. That means if the heart rate goes up the cardiac output will go up. The stroke volume is how much the heart pumps out with each contraction. That can go down if the heart rhythm is off like in atrial fibrillation. ...Read more

Atrial tachycardia - eps / rfa advised by the cardiologist. What does that mean?

Ablation: Ablation therapy is done to destroy tissue in the heart that is causing electrical or mechanical problems. Usually the technique used is radiofrequency energy like microwaves but there are also other techniques. Most commonly these are performed by electrophysiology specialists. ...Read more

Holter 48 hr showed 31 xtra beats from atria. If they cause premature ventricular contractions is it dangerous?Read that prexcitaion can cause death??

Atrial arrhythmias: Most probably you don't have preexcitation. You probably have atrial ectopics (extra beats) common with stress, caffeine, hormonal changes, lack of sleep. Rare for pre-excitation to cause death. ...Read more
