How Successful is Cardioversion?

  Initial success of electrical cardioversion for Atrial Fibrillation was 65.7%. At one year, 47% remained in Normal Sinus Rhythm.   –International Archives of Medicine –December 12, 2009– Short-term and long-term success of electrical cardioversion in atrial fibrillation in managed care system Introduction Atrial Fibrillation (AF) is the most common dysrhythmia encountered in clinical practice, accounting for approximately one third of hospitalizations for cardiac rhythm disturbance. Electrical cardioversion (ECV) is used to restore sinus rhythm (SR), both to alleviate associated… Keep Reading


How Many Times Can You Have a Cardioversion?

The Skeptical CardiologistApril 9, 2016 Atrial Fibrillation: How Many Times Can You Shock the Heart The most effective method for getting a heart that is in atrial fibrillation back to normal rhythm is a called an electrical cardioversion. I’ve tried to come up with a good alternative or descriptive term for this procedure for my patients, such as “resetting” or “rebooting” the heart, but the term that seems to best resonate with patients is “shocking” the heart. How Does Electrical  Cardioversion… Keep Reading


Six Myths about Atrial Fibrillation

Myth #1: If you have just one or two episodes of atrial fibrillation, it probably won’t come back. Cleveland Clinic February 5, 2013 Atrial Fibrillation – Dispelling 6 Myths Knowing the facts can make all the difference Butterflies in the stomach can signal excitement or nervousness. But fluttering in the chest can signal a short circuit in the heart’s natural electrical wiring, or arrhythmia. Atrial fibrillation (A-fib), the most common arrhythmia in the United States, is an off-speed rhythm in… Keep Reading


What is Cardioversion?

  Cardioversion is a medical procedure by which an abnormally fast heart rate (tachycardia) or other cardiac arrhythmia is converted to a normal rhythm using electricity or drug   from Wikipedia  [of all the websites explaining cardioversion, Wikipedia provided the most detail]   Cardioversion Synchronized electrical cardioversion uses a therapeutic dose of electric current to the heart at a specific moment in the cardiac cycle, restoring the activity of the electrical conduction system of the heart. Pharmacologic cardioversion, also called chemical cardioversion, uses antiarrhythmia medication instead of an electrical shock. Electrical To perform synchronized electrical cardioversion, two electrode pads are used (or, alternatively, the traditional… Keep Reading


How Important Are Short AFib Episodes? (SCAF)

Paul Dorian, a Canadian cardiologist,  “Warned about relentless seeking of information when we do not know how to deal with the data the screening tests provide, especially since there is likely harm from a diagnosis of SCAF (anxiety, possible therapy adverse effects, insurability, a label of illness, cost, etc.) Drjohnm.org May 25, 2017 How important are short AF episodes? A study presented at the recent Heart Rhythm meeting in Chicago has added more uncertainty about the significance of short-duration AF episodes. Before… Keep Reading


Risks of Warfarin

The most common type of bleed necessitating hospitalization was gastrointestinal bleeding, which accounted for 62% of cases.     Medscape –Sue Hughes –November 27, 2012– Major Bleeds With Warfarin in AF Are Often Fatal Results of a large observational study of warfarin use in AF patients suggest that major bleeding rates are higher than in clinical trials and are often fatal. The authors, led by Tara Gomes (University of Toronto, ON), conclude that the study “provides timely estimates of warfarin-related… Keep Reading
