These devices started as bulky units with limited functions but have now become smaller and more capable.
Pacemaker technology’s progress shows this change clearly. Old pacemakers needed major surgery and had risks from lead problems. Modern leadless pacemakers go directly into the heart through a catheter in the femoral vein. This method eliminates leads and reduces infection risks.
New advances have created dual-chamber pacemakers that coordinate all four heart chambers’ timing. These devices copy natural electrical pathways, while rate-responsive versions adjust pacing based on activity level. Scientists at the University of Chicago have created a wireless, light-powered pacemaker. This flexible silicon membrane fits the heart’s surface and delivers electrical current when light hits it.
Battery technology has improved too. Modern pacemakers last 5-7 years on average, and the newest ones can work for 10-15 years. Patients need fewer replacement procedures as a result.
Telemedicine and remote care systems
Telemedicine has changed how doctors deliver healthcare. The Australian Bureau of Statistics reports that 26.2% of people seeking mental health services used telehealth at least once in 2023-24. Rural, regional, and remote communities benefit most from this approach when they need regular access to specialists.
Remote patient monitoring (RPM) technologies help healthcare providers gather current information about patients’ health at home. This affordable approach keeps patients out of expensive hospitals while collecting ongoing health data. Common technologies include:
- Wearable devices that track health conditions and activities
- Implantable technologies that work with smartphone apps to gather data
- Digital platforms that show health trends over time
The COVID-19 pandemic made telehealth more common and showed how it keeps healthcare running during crises. Telehealth helps doctors create individual-specific treatment plans, prevent unnecessary hospital stays, and act quickly when health problems start.
AI integration with telehealth promises to improve healthcare delivery even more. AI algorithms can analyze big datasets and find patterns that doctors might miss, which leads to more precise and individual-specific care.
