Atrial Flutter with 1:1 conduction - risks?
An_252527 posted:
I have atrial flutter with 1:1 conduction - thus my heart rate can be 270-300 beats per minute when during an episode. The episodes are typically brief - from under a minute to a max of about 5 minutes. An ultrasound shows that the heart muscle is fine despite this. It has been recommended that I have an RF ablation, but I am skeptical. I have read about the risks, but the information seems mixed. Is this life threatening? Or is it just an annoyance?

"Is this life threatening? Or is it just an annoyance?"

This needs to be discussed with your doctor(s).

I have. His answer was clear as mud - just like yours. It is a shame what lawyers have done to doctors.

Thank you for taking the time to respond.
James Beckerman, MD, FACC responded:
Atrial flutter with 1:1 conduction can put a person at risk of passing out, having a heart attack, or developing a reduction in heart function over time.

Ablations can be a very good option for atrial flutter, as they are low risk and generally curative, such that the person does not need to take medication in the long term to treat the heart rhythm. It's true - there are low risks to any invasive procedures. But in some cases they can be the better option.
