The Generator by OpenHeart

Your device knows a lot about your heart.
You should too.

Wherever your heart takes you, the Generator goes with you. If you have an implanted cardiac device, you're in the right place.

Free · Weekly · No jargon · Written for patients

Sound Familiar?

"What does this term on my report actually mean?"

"My device fired. What do I do right now?"

"Why am I waiting three weeks to hear if this is serious?"

"Is what I'm feeling normal — or should I be worried?"

"What is my device actually detecting right now?"

"Am I the only one who feels this way?"

Every Issue Contains

One question. Six ways to understand it.

Each issue takes a real question, device event, or patient experience and examines it from every angle.

The Signal

What happened?

A real device event, symptom, or patient question — the starting point of every issue.

The Decode

What does it mean?

A deeper explanation of the medicine, physiology, and technology behind the event.

Device Decoder

What does that word mean?

One clinical term explained at three levels — plain language to deeper clinical understanding.

While You Wait

What can I do now?

Practical questions, observations, and next steps while you wait for your next clinical conversation.

You Are Not Alone

Has someone else been through this?

The emotional and human side of living with an implanted cardiac device, in patient voices.

The Close

What should I take away?

Dr. Choudhuri's clinical perspective — and the questions worth carrying into your next appointment.

About the Generator

The Generator

Understand your heart device with confidence.

The Generator is a free educational newsletter created for people with pacemakers, ICDs, CRT devices, and implantable heart monitors.

Each issue explains how your device works, what your data means, and what questions to ask at your next appointment — in language that's easy to understand.

Written by cardiac device specialists, reviewed for accuracy, and designed around the questions real patients actually ask — because you carry the device, and you deserve to understand it.

The Information Gap

The technology has become
extraordinarily intelligent.
The experience of living with it has not kept up.

"A pacemaker is far more than a piece of hardware. It senses. It records. It responds. It stores information about your heart. Yet the person carrying it can still leave an appointment wondering: what exactly is happening inside me?"

The Generator was created to help close that gap. Not by replacing your physician. Not by diagnosing you. And not by giving you more medical jargon.

By helping you understand the technology, terminology, and questions surrounding your care — well enough to become a more informed participant in it.

Before Device / After Device

The implant takes less than 2 hours. Learning to live with it can take much longer.

Receiving an implanted cardiac device can create a dividing line in a person's life. There is the physical recovery. And then there is something harder to describe.

Before Device

A diagnosis. Questions about what comes next. Preparing for a procedure that will change the rhythm of your daily life.

After Device

Every heartbeat feels important. You wonder whether the device just did something. Whether you can exercise, travel, sleep normally.

Dr. Indrajit Choudhuri

Cardiac Electrophysiologist · Researcher · Inventor

"My goal isn't to make patients their own doctors. It's to help them understand enough to become active participants in their own care."

Dr. Choudhuri is a practicing cardiac electrophysiologist whose career has been spent inside one of medicine's most technically sophisticated fields: understanding and treating disorders of the heart's electrical system. The Generator grew from patients who kept having questions — important questions — in the long stretches between encounters with the healthcare system.
