Electrocardiographic Abnormalities in Homebound Adults Aged ≥80 Years Receiving Comprehensive Geriatric Home Care
This retrospective study of 556 homebound Peruvian adults aged 80 and older, assessed via tele-electrocardiography, reveals that arrhythmias are more prevalent in those aged 90 and above, while conduction blocks are significantly more common in men than women within the 80–89 age group.

For many people, growing older means facing a quiet paradox: the body's needs become more complex, yet the ability to travel to a doctor becomes more difficult. This is especially true for the "oldest-old," those aged eighty and beyond, who often live with frailty, memory challenges, and a reliance on caregivers. In the medical world, the heart is a primary concern, but checking its rhythm usually requires a trip to a clinic, a barrier that leaves this vulnerable group largely invisible in research. The standard tool for listening to the heart's electrical signals is the electrocardiogram, a test that records the heart's beat on a graph. As people age, these electrical patterns naturally change, and problems like irregular beats or blocked signals become more common. However, most of what we know about these changes comes from people who are healthy enough to walk into a hospital. We know very little about the hearts of those who are too frail to leave their homes, particularly in regions where advanced cardiac care is scarce.
In Peru, a team of researchers decided to look directly at this hidden population. They turned to a home-care program called PADOMI, which serves adults who are largely dependent on others for daily life. To bridge the gap between homebound patients and specialists, the team used a telemedicine system. This allowed them to capture electrocardiograms during home visits and send the data instantly to cardiologists for review. The researchers focused on 556 adults aged eighty or older who were part of this program. They split the group into two categories: those between eighty and eighty-nine years old, and those who had reached the milestone of ninety or older. Their goal was simple: to see what their hearts looked like on the electrical graph and to understand if age or gender made a difference in what they found.
The results revealed a clear shift as people moved into their ninth decade. The researchers found that irregular heartbeats, known as arrhythmias, were significantly more common in the group aged ninety and older compared to the slightly younger group. In the ninety-and-up group, nearly one in five people showed signs of these rhythm disturbances, whereas the rate was lower for those in their eighties. This confirms a long-held belief that heart rhythm issues become more frequent with advanced age, and it provides new data characterizing this homebound group that is rarely studied. The team also looked at conduction blocks, which are delays or interruptions in the electrical signals that tell the heart muscle when to squeeze. While these blocks were slightly more common in the oldest group, the difference was not strong enough to be considered a definitive trend.
A more surprising discovery emerged when the researchers looked at gender. In the eighty-to-eighty-nine age group, men were much more likely to have conduction blocks than women. This pattern aligns with what doctors have seen in younger populations, where men often face higher rates of these specific electrical delays. However, once the patients reached the age of ninety, this gender gap seemed to vanish. In the oldest group, the rate of conduction blocks was nearly identical for men and women. The researchers noted that this equalization was an interesting observation that warrants further study, though they could not say for certain why it happened. It is possible that the biological changes of extreme aging affect men and women in similar ways, perhaps leveling out differences that were visible in younger years.
The study also highlighted the value of bringing medical tools to the patient. By using tele-electrocardiography, the team was able to assess the heart health of people who would otherwise have no access to a specialist. They found that a significant portion of these homebound adults had electrical abnormalities that could impact their care. While the study was limited by its design—it looked at a snapshot in time rather than following patients over years, and faced constraints such as limited statistical power for certain comparisons and reliance on a single care pathway—it successfully characterized the landscape of heart health for a group that has been overlooked. The findings suggest that as people reach the very end of their lives, the patterns of heart disease may shift, and that gender differences observed in middle age might not tell the whole story for the oldest-old. Ultimately, the work proves that it is possible to reach the most isolated patients and understand their needs, offering a new way to care for the fastest-growing segment of the global population.
