Smartwatches & Heart Health: When to See a Doctor, According to Tampa Cardiologist

Many of us are increasingly reliant on smartwatches and fitness trackers to monitor our health, but understanding what the data means – and when to seek medical attention – can be challenging. A recent case in Tampa, Florida, highlights the potential benefits of these devices, while also underscoring the importance of context and professional medical evaluation.

Aaron Shaffer, a 23-year-old preparing for medical school, discovered a potential health issue through his Apple Watch. He noticed his heart rate dropping into the low 40s during sleep. While an active individual, this was an unusual finding that prompted him to consult with Dr. Jesal Popat, an interventional cardiologist with Orlando Health in Tampa. The investigation ultimately led to a diagnosis of sleep apnea – a condition he likely wouldn’t have discovered without the smartwatch’s monitoring capabilities.

“I’d have no idea because no one is watching you sleep,” Shaffer explained. “It’s the smartwatch that caught that initially, and then it required further testing, which is why I saw the pulmonologist and that’s how I got diagnosed.”

This case illustrates a growing trend: wearable devices are becoming valuable tools for identifying potential health concerns. However, experts caution against self-diagnosis and emphasize the need for careful interpretation of the data.

Dr. Popat stresses the importance of context. “So, the context really matters. It depends on how you’re feeling at the time,” he said. “For example, if you’re just watching TV and you’re getting a high heart rate alert, that may be more concerning than if you were taking a walk or if you were at a theme park riding a rollercoaster.” A spike in heart rate during physical activity is expected, while an unexplained elevation at rest warrants further investigation.

The utility of smartwatches extends beyond detecting irregular heart rhythms. Dr. Popat also noted that these devices can potentially signal the onset of illness. “If you’re noticing that your heart rate variability is very low, your respiration rate is higher, or that your heart rate is higher, that could be indicative of an infection, that you might be ill, coming down with an upper respiratory infection or a cold.”

The increasing availability of features like electrocardiogram (ECG) capabilities on some smartwatches further enhances their potential for heart health monitoring. However, these features are not substitutes for traditional medical evaluations.

According to experts at MedStar Health, smartwatches are best used as a complement to, not a replacement for, professional medical care. These devices can be excellent for tracking physical activity and sleep patterns, motivating individuals to achieve their fitness goals, and raising awareness about their overall well-being. But interpreting the data requires a nuanced understanding of individual health status and potential influencing factors.

If a smartwatch alerts you to an irregular heart rhythm or reveals concerning trends in your heart rate, it’s crucial to discuss these findings with your primary care provider or a cardiologist. They can determine if further testing is necessary. A consistently high resting heart rate (above 100 beats per minute) or an unusually low resting heart rate (below 50 beats per minute, in individuals who are not athletes) should also prompt a medical consultation.

February is American Heart Month, a reminder of the importance of proactive heart health management. Dr. Popat also highlighted the significant role sleep plays in cardiovascular health, suggesting that investing in a smartwatch or ring that monitors sleep patterns can be a worthwhile step towards better overall health.

smartwatches can empower individuals to take a more active role in their health, but responsible use requires awareness of their limitations and a commitment to seeking professional medical guidance when needed. As Shaffer advises, “Be aware. Do your own research but don’t be your own doctor.”
