Atrial fibrillation and Congestive heart failure

posted in: Videos | 0


It’s been shown that people whose hearts are in atrial fibrillation live shorter lives than people whose hearts are not in atrial fibrillation. That’s because it can lead to congestive heart failure or stroke. What makes atrial fibrillation so insidious and dangerous is the range of symptoms can go from asymptomatic to a racing heartbeat, shortness of breath or even a feeling of impending doom.

Atrial fibrillation and Congestive heart failure – This video describe how atrial fibrillation, and congestive heart failure interact. Managing atrial fibrillation and be very tricky in patients that also have congestive heart failure.


Thank you for visiting Dr. AFib, I am Dr. Morales. In today’s video segment we are going to talking about atrial fibrillation and congestive heart failure together. February is heart month and so I wanted to make some videos why to discuss not just atrial fibrillation but how atrial fibrillation affects other heart conditions and looking at your heart as a whole, and in this segment, we are going to talking about atrial fibrillation and congestive heart failure which is commonly called CHF.

CHF can refer to a few things. Most commonly It’s related to a weak heart, but it can also be seen to as a frozen heart. And in both circumstances, the heart just doesn’t pump blood efficiently to the rest of your body and leads to backflow which can lead to fluid in your lungs which can cause shortness of breath, or swell your legs which are the most common symptoms of congestive heart failure.

So how does atrial fibrillation affect congestive heart failure, well there are two ways that they can interact. One, it can be the primary cause of congestive heart failure or two, it can be secondary because of congestive heart failure.

So let’s talk about the first one in which is atrial fibrillation is the cause of congestive heart failure.

Sometimes when patients are first diagnosed with atrial fibrillation, they don’t necessarily feel the heart going fast or skipping they just started feeling more short of breath. So when they’re finally diagnosed atrial fibrillation, their heart may have gone quickly for several weeks or even months at a time and as a consequence of the core going consistently fast all the time the heart function becomes week.

It becomes weaker than usual and in those situations, the atrial fibrillation is the cause of the congestive heart failure. Now usually when they are first diagnosed you have to do things like looking at coronary heart disease make sure that that’s also not a cause as well, but if at the end of points to only atrial fibrillation being the cause of the congestive heart failure it’s called tachycardia-mediated cardiomyopathy.
