![]() ![]() Because the atria don’t contract normally in a-fib, blood is more likely to pool there and clots can form. Also, if the cause of your heart flutters is a-fib, you are at a much higher risk of heart attack and stroke. ![]() In this case, the underlying cause of the condition requires treatment, in order to prevent the PVCs from triggering more complex-and potentially deadly- arrhythmias. If the cause of your heart flutters is a-fib, or your heart has a structural abnormality or is damaged from a prior heart attack, then the fluttering is more of a concern. It’s also a good idea to continue with follow-up visits so your doctor can monitor your heart to make sure a more significant problem doesn’t develop. Patients in this category may be prescribed a low-dose beta blocker to help minimize the fluttering sensation and to calm the heart. Some risk.Īt least one study has linked a high frequency of PVCs (more than 30 per hour) with greater risk of heart disease and sudden cardiac death, so your risk increases somewhat if you have a lot of them. I usually recommend that folks in this category focus on lifestyle changes, like learning how to reduce stress levels and avoiding foods that are known to cause heart palpitations, that can help lessen the frequency of PACs and PVCs. We call these “benign PACs or PVCs”-and, in fact, virtually everyone experiences this type of palpitation at some time in their life, including me. If your heart flutters are caused by occasional PACs and/or PVCs, and your heart is healthy and has no structural abnormalities, the fluttering is not dangerous. But in general, most people fall into one of three groups: Minimal risk. The answer to this question depends on your specific situation. ![]() Exactly How Dangerous Are Heart Flutters? These conditions can also cause a-fib, though a-fib is also often linked to an improper functioning of the heart’s natural pacemaker.
