I had my ASD fixed with Amplatzer device one year ago when I turned 45 years old. I am feeling better, more energy, I can exercise, and I am lucky I did not get a stroke or atrial fibrillation beforehand. I have noticed since my ASD closure, I have sinus bradycardia: my heart rate at rest is 40 … it can dip down to 35 if I am really relaxed. I did get a stress test and my heart rate goes up with exercise. By the way, I am not an athlete and my heart rate is not low because I work out a lot!!! I am not a couch potato, and I do go for long brisk walks but usually that is the extent of my exercise. I do not have any chest pain or shortness of pain symptoms when my heart rate is low, but I do get dizzy and feel off balance when I am tired. My cardiologist said that as long as I do not have symptoms, I do not need any treatment for the sinus bradycardia … the only treatment would be a pacemaker anyway. I do worry as I get older that my heart rate will slow down even more as many people’s heart rate drops as they age.
Is there anyone experiencing sinus bradycardia after Amplatzer device? How long have you been living with it? Any changes over time? Does it get better/worse? Did you need a pacemaker in the long run?
