Can't tolerate amiodarone / multaq for AFib. Unbearable side effects.  Been in rhythm with chemical cardioversion. Alternatives? ? My
 doc say no.

Treatments for AFib: Electrohysiologists may be able to map your heart to find the foci which need to be ablated (ablation therapy)in order to stop the atrial fibrillation, since you are sensitive to medications. There are other medications which will control the rate of atrial fibrillation (such as old fashioned digitalis, slowing the rate, blocking it down, and calcium channel blockers which you might tolerate. ...Read more

Who can have cardioversion?

Who can have cardioversion?

Almost anyone: If there is any compromise in bp, consciousness, breathing, anyone can be cardioverted. If more chronic, then making sure there is a low probability of a clot inside the heart (that could be disrupted and cause an embolic event), sorting the need for prophylactic blood thinning to avoid a clot, making sure the atria (upper heart chambers) are not too large (reduced success) help select patients. ...Read more

What purpose is dc shock for cardioversion?

Reset button: Enough current applied through the chest wall and into the heart will basically depolarize all of the heart muscle at once. As the heart electrically recovers, "normal" electrical activity has a chance to return - basically it resets the electrical activity of the heart. ...Read more

Define vigorous exercise after a cardioversion.

Define vigorous exercise after a cardioversion.

Vigorous exercise: I can't be 100% sure of what you are trying to get at so I am going to assume that someone was told not to do vigorous exercise following cardioversion. That being said, there is no formal guideline on this subject as far as i know. Your doctor decides what kind and how "vigorous" exercise can be after you are converted. I am used to patients being generally allowed to get back to business. ...Read more

Cardioversion: We use electrical cardioversion to convert tachyarrhythmias to normal rhythm when appropriate. When the rhythm we are shocking is atrial or ventricular fibrillation, we call the cardioversion defibrillation. ...Read more

How much energy (in watts) is used in a cardioversion?

How much energy (in watts) is used in a cardioversion?

100-360 J: First a couple of definitions: energy is usually expressed in joules (j). Watts are a measure of the rate of energy used, 1 watt = 1 joule/sec. Most external cardioversions use between 100 and 360 joules (or 100-360 watt-sec). Internal defibrillators deliver about 20-45 j. ...Read more

What is difference between cardioversion and defibrillation?

Voltage: Cardioversion means using a stimulus to change the heart's beat from an abnormal rhythm to a normal one. Certain drugs can be used, or electricity, usually only a low voltage is required unless the abnormal rhythm is a very dangerous one called ventricular fibrillation. When the rhythm is ventricular fibrillation, usually more voltage (electricity) is needed, and it is called defibrillation. ...Read more
