Known for her iconic role as Claire in the Modern Family, Julie Bowen who is a versatile American actress, recently spoke about the rare heart condition she's was diagnosed with at 29. Speaking about it on the first episode of 'Inside of You' with host Micheal Rosenbaum, Julie revealed her condition 'shy sinus syndrome' that caused her to have a low resting heart rate. She also explained how, due to the condition, she also has had a pacemaker put in place. Lifelong Low Heart Rate and a Surprising Diagnosis Bowen explained that she has always had a remarkably low resting heart rate, even around 30 beats per minute at times, a significant deviation from the normal range of 60 to 100 beats per minute for women. This was due to sick sinus syndrome, a heart rhythm disorder exacerbated in her case by hypervagotonia, an overactive vagus nerve. Despite being a competitive runner, her low heart rate was a constant, though initially unexplained, characteristic. The John Hopkins Medicine explains that sick sinus syndrome (SSS) occurs when your heart's natural pacemaker, the sinoatrial (SA) node in the upper right chamber, becomes damaged and can no longer regulate your heartbeat properly. This damage can result from underlying medical conditions or certain medications, leading to heartbeats that are too slow, too fast, or fluctuate between both extremes. Recognizing the Symptoms You might have SSS with no symptoms at all, or only mild ones. However, if symptoms do appear, they can include: DizzinessFainting (syncope)Shortness of breath, especially with physical activityHeart palpitations (a fluttering or pounding sensation in your chest)Chest painHow Is Sick Sinus Syndrome Diagnosed? The turning point for Julie came thanks to her sister, Annie Luetkemeyer, who had just graduated from medical school. During a family vacation, her sister, still in the habit of carrying a stethoscope, insisted on listening to Bowen's heart. "That is not what they've been telling you, and it's not runner's heart or whatever. That means you need to go to a cardiologist," her sister declared, refusing to let the issue drop Your healthcare provider might suspect SSS based on your symptoms, but these symptoms can be common to many other conditions. To confirm a diagnosis, your provider will likely perform an electrocardiogram (ECG), which records your heart's electrical activity, rate, and rhythm. If you're not experiencing symptoms during the ECG, the results may appear normal. Other diagnostic tests that may be used include: Stress test: An ECG performed while you exercise on a treadmill.Holter monitor: A portable device you wear for over 24 hours to continuously record your heart's electrical activity.Event recorder: A device worn for several days that records your heart rate only when symptoms occur.Electrophysiologic testing: A hospital procedure where catheters are threaded into your heart through a vein in your thigh to study its electrical system.Echocardiogram: An ultrasound of your heart to check for structural problems. Treatment Options For SSS About a month after her sister's crucial warning, Bowen was filming the pilot for "Ed" when she was faced with the reality of needing a pacemaker. Initially, the news was daunting. "I was like, 'Oh my God. My life is over. This is so weird. I'm gonna die,'" she recalled. However, doctors explained that while the condition wasn't immediately fatal, it would lead to her frequently passing out. Bowen described a sensation of lightheadedness, particularly when she was relaxed, feeling "like I'd been holding my breath for a while." The critical warning that solidified her decision was the risk of passing out while driving and potentially harming someone. "Oh, well, then give me the Goddamn pacemaker," she decided. Her pacemaker is now set to ensure her heart rate doesn't drop below 45 beats per minute. She shared that the surgical insertion was done discreetly through her armpit, leaving no visible scar. While she's had to have the batteries replaced three times, she largely forgets about it now, a testament to how seamlessly it has integrated into her life. While this is one way to treat her condition, here are some other ways your doctor may choose to go about your treatment, Medication adjustment If certain medications are contributing to your SSS, your healthcare provider may change your prescription. Blood thinners Because SSS can increase the risk of blood clots forming in the heart and leading to a stroke, you may be prescribed blood thinners as a preventive measure.
