Before she ever took her first breath, Rebeca Andrea Zaldaña Limas was already fighting for her life.

Inside the womb, where life is meant to grow quietly and safely, her tiny heart was struggling to keep up. Doctors discovered she had complete heart block, a rare and dangerous condition that disrupts the electrical signals controlling the heartbeat. For Rebeca, that meant her heart was beating at a critically low rate—just 30 to 40 beats per minute.

For an unborn baby, that kind of rhythm isn’t just abnormal. It’s life-threatening.

A Diagnosis That Changed Everything

The diagnosis came with urgency and fear.

Rebeca’s condition was linked to maternal autoimmune complications, meaning her body was under attack before she even entered the world. Doctors knew they were racing against time, but options were limited while she remained in the womb.

Every day became a fragile balancing act.

Hope was there—but so was the reality that survival was far from guaranteed.

Born Too Soon, But Not Without a Fight

At just 27 weeks, doctors made the decision they could no longer wait.

Rebeca was delivered prematurely, weighing only two pounds.

She was incredibly small. Fragile. Vulnerable.

But she was alive.

From the moment she entered the world, a team of specialists moved quickly to stabilize her. Her heart could not maintain a safe rhythm on its own, so doctors relied on an external pacemaker—an urgent, temporary solution to keep her alive.

Inside the NICU, every second mattered.

A Race Against Time—and Innovation

In those early days, survival was uncertain.

The external pacemaker helped, but it wasn’t a long-term solution. Rebeca needed something more permanent—something that could support her tiny heart as she grew.

That’s when her medical team made a bold, unprecedented decision.

At just 30 weeks, Rebeca became one of the smallest patients ever to receive a Micra pacemaker—a device typically used in adults.

The challenge was immense.

The device wasn’t designed for a body so small. The procedure required extraordinary precision, innovation, and courage from the medical team.

But they moved forward.

And it worked.

A Heart That Finally Found Its Rhythm

For the first time, Rebeca’s heart began to beat steadily on its own.

It was more than a medical success—it was a turning point.

After weeks of uncertainty, there was finally something her family could hold onto.

Hope.

130 Days of Waiting, Watching, and Believing

Rebeca’s journey didn’t end with the procedure.

She remained in the NICU for 130 long days.

Days filled with monitoring, procedures, and constant vigilance.

Days where progress came slowly, and setbacks were always possible.

Through it all, her parents stayed by her side.

They watched her fight—quietly, persistently—against odds that once seemed impossible to overcome.

Every breath.
Every heartbeat.
Every day she survived became a victory.

The Day Everything Changed

Then came the moment they had been waiting for.

Rebeca was strong enough to go home.

The machines that once surrounded her were no longer needed. The constant beeping of monitors faded into silence.

Her heart—once so fragile—was now steady.

Supported by a device that had given her a second chance at life.

More Than Survival

Today, Rebeca is no longer defined by hospital walls or medical uncertainty.

She is thriving.

An energetic, joyful little girl whose life tells a story far bigger than her beginning.

Her journey is one of resilience—but also of possibility.

It’s a reminder of what happens when cutting-edge medicine meets determination, and when innovation is driven by the will to save a life.

A Family Forever Changed

For her parents, the memories of those early days remain vivid.

The fear.
The waiting.
The moments where hope felt fragile.

But so does the gratitude.

Gratitude for the doctors who took risks.
For the technology that made survival possible.
For the strength their daughter showed before she even understood the world.

When Science and Courage Meet

Rebeca’s story stands at the intersection of medical innovation and human resilience.

A baby born too soon.
A heart that couldn’t keep rhythm.
A solution never meant for someone so small.

And yet—it worked.

A Living Reminder of Hope

Her journey is more than a story of survival.

It’s a reminder that even in the most uncertain moments, there is still a path forward.

That breakthroughs happen.
That strength can exist in the smallest bodies.
That hope doesn’t disappear—it waits.

And sometimes, it beats quietly—

one heartbeat at a time.
