3. Shortness of Breath: The Struggle for Air
Shortness of breath, or dyspnea, is another common symptom of AFIB that often appears early in the course of the condition. It’s a frightening experience when breathing, an action usually performed effortlessly, suddenly becomes a struggle. When AFIB is the cause, shortness of breath typically occurs because the heart isn’t pumping blood efficiently, leading to a decrease in the amount of oxygen reaching the body’s tissues.
Shortness of breath in AFIB can occur at any time but is particularly noticeable during physical activity. You might find yourself gasping for air after climbing a flight of stairs that you used to ascend without difficulty, or you may become breathless when carrying out other routine activities like walking to the mailbox or doing household chores.
It’s important to note that, much like palpitations and fatigue, shortness of breath is not exclusive to AFIB. It can be a symptom of numerous other conditions, including asthma, chronic obstructive pulmonary disease (COPD), heart failure, and anxiety disorders. However, when it occurs alongside other AFIB symptoms, shortness of breath can be a strong indicator of this heart rhythm disorder.
Shortness of breath can be a particularly alarming symptom because it can severely impact your ability to function in your daily life. It can limit your activities and can lead to feelings of fear and anxiety, particularly if the cause of the symptom is unknown. If you’re experiencing unexplained shortness of breath, particularly if it’s accompanied by other symptoms such as palpitations or fatigue, it’s crucial to seek medical attention. (3)
